Bassaricyon gabbii is not known to have any direct economic importance to humans.
Brassaricyon gabbii is typically found from Nicaragua to Bolivia, where it is locally abundant and it is sparsely distributed in the western Amazon basin.
Biogeographic Regions: neotropical (Native )
Bassaricyon gabbii is found in evergreen forests, and on forest edges. It prefers the upper canopy of the forest and is rarely seen on the ground. Bassaricyon gabbii is found at elevations from sea level to 2,000 m.
Range elevation: 0 to 2000 m.
Habitat Regions: tropical ; terrestrial
Terrestrial Biomes: forest ; rainforest
Not much is known about longevity in B. gabbii. Captive ones have been recorded living as long as 25 years. The lifespan in the wild is thought to be no more than 10 years.
Range lifespan
Status: captivity: 25 (high) years.
Average lifespan
Status: wild: 10 years.
Typical lifespan
Status: captivity: 25 (high) years.
Average lifespan
Status: wild: 24.0 years.
Bassaricyon gabbii measures 350 to 470 mm long, with a tail length of 400 to 480 mm. These animals weigh between 970 and 1,500 g. The pelage can range from grey-brown to yellowish. Faint bands are visible on the tail. It has small rounded ears and a flattened head. Both males and females have similar body size.
Range mass: 970 to 1500 g.
Range length: 750 to 955 mm.
Average length: 850 mm.
Sexual Dimorphism: sexes alike
Other Physical Features: endothermic ; bilateral symmetry
The predators of B. gabbii are snakes and large cats like the jaguar (Panthera onca). Humans are known to kill them, but not for food.
Known Predators:
Bassaricyon gabbii feeds on fruits, nectar, flowers, insects, and small vertebrates. It is primarily a frugivore and prefers to feed in fruit trees. However, it is reported to consume considerably more meat in captivity than Potos flavus, and actively hunts warm-blooded animals.
Animal Foods: birds; mammals; amphibians; reptiles; eggs; insects; terrestrial non-insect arthropods
Plant Foods: fruit; flowers; sap or other plant fluids
Primary Diet: herbivore (Frugivore )
Bassaricyon gabbii is a minor seed disperser. In addition, this species may affect populations of small vertebrates upon which it preys, as well as those of large carnivores which prey upon it. It is a known competitor of Potos flavus, and is probably an indirect competitor with many diurnal primate species which feed on fruits.
Ecosystem Impact: disperses seeds
Bassaricyon gabbii can eat fruit being grown commercially, but its population is so sparse that it does not constitute a major threat to crops.
Negative Impacts: crop pest
Deforestation of B. gabbii habitat is reducing the population, but no exact numbers are known. The species is listed on Appendix III of CITES in Costa Rica. IUCN lists the species as Lower risk.
CITES: appendix iii
IUCN Red List of Threatened Species: least concern
It is thought that B. gabbii communicates with conspecifics using sound. Olingos also have glands on either side of the anus that that are used in scent marking. The function of this scent marking may be to attract members of the opposite sex, or to mark territory. Because they are mammals, it is likely that visual signals, such as body posture, are used in some instances. Tactile communication is undoubtedly of importance between rivals, mates, as well as between mothers and offspring.
Communication Channels: visual ; tactile ; acoustic ; chemical
Other Communication Modes: scent marks
Perception Channels: visual ; tactile ; acoustic ; chemical
Five species of the genus Bassaricyon are currently recognized by most authorities. However, some think that these five species should be demoted to the rank of subspecies of a single species.
Natives of the Amazon consider the olingos dangerous and kill them on sight.
The breeding system of this species has not been reported. Males are reported to be intollerant of one another in captivity, so it is unlikely that females have multiple mates.
Mating System: polygynandrous (promiscuous)
Breeding in B. gabii is reported to be aseasonal. Gestation lasts approximately 73 to 74 days. At the end of gestation a single offspring is born. Young are altricial, and like most carnivores, are born with their eyes closed. Birth weight is around 55 g. By about 27 days of age, the eyes of the young have opened. Solid food may be consumed as young as 2 months of age. By 21 to 24 months of age, B. gabbii has reached sexual maturity.
Breeding interval: These animals are apparently able to breed at least once per year, and without a definite breeding season may breed more often than that.
Breeding season: Breeding occurs throughout the year.
Average number of offspring: 1.
Range gestation period: 73 to 74 days.
Average weaning age: 2 months.
Range age at sexual or reproductive maturity (female): 21 to 24 months.
Range age at sexual or reproductive maturity (male): 21 to 24 minutes.
Key Reproductive Features: iteroparous ; year-round breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; fertilization ; viviparous
Average birth mass: 55 g.
Average number of offspring: 1.
Male parental care has not been reported for these animals. Females, like females of other mammalian species, take care of infants, providing them with milk, grooming, and protection. Young begin to consume solid food by about 2 months of age, and weaning probably occurs shortly thereafter. It is not known how long the young stay with their mothers, but, as with most carnivores, which must learn how to hunt for prey, young B. gabbii probably have some post-weaning association with their mothers.
Parental Investment: no parental involvement; altricial ; pre-fertilization (Protecting: Female); pre-hatching/birth (Provisioning: Female, Protecting: Female); pre-weaning/fledging (Provisioning: Female, Protecting: Female); pre-independence (Provisioning: Female, Protecting: Female)
The Bassaricyon gabbii, also known as the bushy-tailed olingo, Northern olingo, or the olingo is part of the Procyonidae family. B. gabbii is called olingo solely because it is the most commonly seen of the species. It is locally abundant and is sparsely distributed in the western Amazon basin. This Bushy-tailed olingo is one out of the five species in the genus, Bassaricyon (Prange & Prange, 2009). B. gabbii is classified as a Low Risk Near Threatened mammal according to the International Union for Conservation of Nature and Natural Resources (Prange & Prange, 2009). Often, researchers confuse Kinkajou and olingo’s (Prange & Prange, 2009). In 1955 there was a live specimen that was collected in Panama and was brought to the United States. This specimen was sadly mistaking for a Kinkajou (Manville 1956). As mentioned, olingos and kinkajous are very similar and can be easily confused. For years now, these two have likely competed for resources (Kays, 2000). Studies have stated that kinkajous have dominated over B. gabbii in the wild but its geographic and local distribution could be influenced in part by competition with kinkajous (Kays, 2000).
Bassaricyon gabbii is typically found in Central America from Nicaragua through Costa Rica and western Panama (Hall, 1981). Some reporters have said that it has been sighted from Honduras and Guatemala (Helgen et al, 2013). Northern olingo’s are rare at sea levels and is usually found inhibiting montane and tropical moist forests from 1,000 meters (3,300 ft) up to around 2,000 meters (6,600 ft) in elevation (Helgen et al, 2013). In South America, it has been reported that B. gabbii has been found in Venezuela, Colombia, Ecuador, and Peru (Prange & Prange, 2009). B. gabbii usually inhibits evergreen forests and forest edges (Pontes & Chivers, 2002). When found in deciduous forests or highly disturbed regions, it is considered an unusual sitting (Pontes & Chivers, 2002).
According to the International Union for Conservation of Nature and Natural Resources the B. gabbii is considered a Lower Risk/Near Threatened animal (Prange & Prange, 2009). It is said that the largest threat to the olingos are habitat destruction and degradation (Prange & Prange, 2009). B. gabbii, are protected by the Colombian legislation and nowhere else in the world (Prange & Prange, 2009).
In our ecosystem, the B. gabbii plays a minor role in dispersal of seeds. For humans, some people will say that the B. gabbii will eat the fruit that is being grown for commercial use but because of it’s sparse locations it is not fully known if B. gabbiis are a threat to crops (Pontes & Chivers, 2002)
Adult Bassaricyon gabbii (Northern olingo) has a head to body length of between 36 to 42 centimeters, which is about 14 to 17 inches. Bassaricyon gabbii weighs around 1.2 to 1.4 kilograms, which is equivalent to 2/6 to 3.1 pounds (Saavedra-Rodriguez & Velandia-Perilla, 1875). Its tail is between 38 to 48 centimeters (15 to 19 inches) (Saavedra-Rodriguez & Velandia-Perilla, 1875).
Northern olingo is an arboreal animal that has longer hind legs than it is fore legs. It has a long, bushy tail that is used as a balancing organ (Reid, 1997). The tail of an olingo is non-prehensile, non-tapering, and slightly tufted at the end (Reid, 1997). B. gabbii has a number of faint rings of darker fur along its tail.
Olingo’s face is short and rounded with large eyes and short round ears (Saavedra-Rodriguez & Velandia-Perilla, 1875). The fur ofBassaricyon gabbii is a brown and or grayish brown color that covers over most of the body. This then becomes slightly darker along the mid of the back. The under parts of the animals body has a light cream to yellowish coloring to it (Saavedra-Rodriguez & Velandia-Perilla, 1875). Interesting enough there is a band of yellowish fur that runs around the throat and sides of the head (Prange & Prange, 2009).
The feet of a B. gabbii are hairy with flattened toes ending with short and curvy claws (Prange & Prange, 2009). It is documented that only the females have one “pared of teats” that are located on the rear part of the abdomen (Prange & Prange, 2009).
In order to protect themselves from predators, Bassaricyon gabbii has a pair of anal scent glands that helps them secret foul smelling chemicals when they are frightened or feel threatened (Saavedra-Rodriguez & Velandia-Perilla, 1875).
The call of a Northern olingo posses two notes, "whey-chuck" or "wey-toll" sound.
Males have been documented to be intolerant to one another in captivity, which would make the females unlikely to have multiple mates (Nowak, 1999). B. gabbii typically breed during the dry season and the mother gives birth to a single young after a gestation period, which lasts for around ten weeks (Prange & Prange, 2009). The young is born with its eyes closed and weights around 55 grams (Nowak, 1999). After 27 days, the baby’s eyes will open. During the nurturing period, the female will take care of the young and provide them with milk, grooming, and protection. The young is mostly a carnivore and is taught to learn how to hunt for prey but it is not known who is teaching them or what the male B. gabbii role in the parenting is (Nowak, 1999). It is documented that at 2 months of age solid food will be consumed and then at 20 to 21 months B. gabbii will have reached sexual maturity (Nowak, 1999). B. gabbiis is documented to live up for twenty-five years in captivity (maybe more) and about ten years in the wild (Prange & Prange, 2009).
Bassaricyon gabbii is a nocturnal herbivore, which feeds entirely on fruits. It has been recorded that they eat about 15 different species of fruits, one of them being figs (Prange & Prange, 2009). Olingos usually forage alone but have often been spotted eating in groups in large fruiting trees (Pontes & Chivers, 2002). B. gabbiis have also been reported to drink the nectar of balsa trees during the dry season as well as consume small mammals such as mice and squirrels (Prange & Prange, 2009). In Monteverde, Costa Rica there was a report that an Olingo captured hummingbirds. Whether or not the hummingbirds were eaten by the olingo was not stated (Prange & Prange, 2009).
There are five subspecies of olingo: B. g. gabbii,B. g. richardsoni, B. g. medius, B.g. neblina, and B. g. pauli(Wozencraft, 2005). There are two lowland olingo species in Panama and Northwestern South America that are the closest relatives ofB. gabbii (Wozencraft, 2005). B. gabbii, predators are known to be the jaguarondi, ocelot, tayra, several boas, as well as humans (not for food purposes but as pets when young). B. gabbii has anal scent glands that produce a horrid smell to “fight” off predators (Nowak, 1999). This scent markings can also serve for mating purposes as well as to mark their territory (Nowak, 1999).

Olingo štíhlý, také medvídek štíhlý (Bassaricyon gabbii), je medvídkovitá šelma patřící do rodu olingo (Bassaricyon), revidovaném v roce 2013. Vědeckými synonymy jsou Bassaricyon lasius, Bassaricyon pauli a Bassaricyon richardsoni. Druh popsal Joel Asaph Allen roku 1876. Vyskytuje se v centru Střední Ameriky v Panamě, Kostarice a Nikaragui, roku 2009 byl nalezen také v Kolumbii v oblasti And. Žije v baldachýnu stálezelených lesů i okrajů lesů v nadmořských výškách 1 600 až 2 000 m n. m., na zem slézá zřídka. Vyskytuje se v blízkosti vody.
Olingo štíhlý měří bez ocasu 35 až 47 cm, ocas dosahuje délky 40 až 48 cm. Váží mezi 970 až 1 500 g. Hlava je plochá, se zaoblenýma ušima. Zbarvení je hnědé, může dosahovat až šedavohnědých odstínů, na zádech tmavší. Spodek těla má barvu smetanovou. Ocas je slabě páskovaný. Druh se vzhledem podobá kynkažu (Potus flavus), se kterou je i zaměňován, na rozdíl od ní se však nedokáže za svůj ocas zachytit.
Je to noční stromové zvíře žijící obvykle samo, byly pozorovány i krmící se skupinky. Žere například ovoce či nektar, loví také malé druhy obratlovců; v porovnání s kynkažu konzumuje masa více, o jeho stravě však bylo získáno málo informací. Slouží jako roznašeč semen. Mezi přirozené nepřátele se řadí jaguár americký (Panthera onca). Systém páření nebyl u druhu zaznamenán, rozmnožování probíhá sezónně. Po 73 až 74denní březosti samice vrhne jedno 55gramové mládě, jež má zavřené oči, které se otevřou asi za 27 dní. Rodičovská péče nebyla zkoumána. Pohlavní dospělosti mláďata dovrší asi ve 21. až 24. měsíci života. V přírodě se dožívá méně než deseti let (délka jedné generace činí 8,4 let), v zajetí se věk ale může vyšplhat až na 25 let.
Nebezpečí představuje odlesňování a lov, Mezinárodní svaz ochrany přírody však druh považuje za málo dotčený i proto, že o něm není známo mnoho informací. Zároveň uvádí doporučení k přehodnocení, až bude více informací zjištěno. V Kostarice je druh zapsán na třetí přílohu úmluvy CITES.
Původní obyvatelé Ameriky olingy zabíjejí, protože se podle nich jedná o nebezpečná zvířata.

Der Mittelamerika-Makibär (Bassaricyon gabbii), auch Schlankbär, Olingo oder Buschschwanz-Olingo genannt, ist eine Art der zu den Kleinbären gehörenden Makibären (Bassaricyon) aus Mittelamerika. Die Art ist die bekannteste Art der Makibären und wird auch von Touristen relativ oft im Biologischen Reservat Monteverde und in anderen Schutzgebieten in Costa Rica gesehen.[1]
Der Mittelamerika-Makibär ist die größte Art der Makibären. Der Körper ist schlank mit relativ kurzen Vorderbeinen und etwas längeren Hinterbeinen. Er erreicht eine Körperlänge von etwa 78 bis 97 Zentimetern, wobei etwa 40 bis 52 Zentimeter auf den Schwanz entfallen. Die Schwanzlänge liegt beim 0,9- bis 1,2fachen der Kopfrumpflänge. Relativ zur Kopfrumpflänge ist der Schwanz damit kürzer als bei den drei anderen Makibärarten. Das Körpergewicht liegt bei 1,1 bis 1,58 Kilogramm.[1]
Das Fell ist dick und weich. Die Körperfarbe ist braun bis graubraun, selten goldbraun, wobei die Bauchseite etwas heller cremefarben, manchmal mit einem orangenen Einschlag ist. Entlang der Mittellinie des Rückens ist das Fell in der Regel dunkler und es besitzt ein gelbliches Band, das sich über den Nacken zu den Ohren zieht. Das breite Gesicht ist grauer als der Körper, die Schnauze ist kurz und spitz. Die Augen sind groß mit zimtfarbener Iris und senkrechten, schmalen Pupillen. Die Ohren sind abgerundet, die Ohrlänge beträgt 2,5 bis 4,4 Zentimeter.[2][1]
Die Füße sind breit mit gebogenen Krallen, die Hinterfüße sind etwa 6,5 bis 10 Zentimeter lang. Anders als beim Wickelbären (Potos flavus), mit dem der Schlankbär häufig verwechselt wird, ist der Schwanz bei diesem nicht greiffähig. Er ist leicht dorsoventral abgeflacht und kann 11 bis 13 dunkle Ringe aufweisen. Die Schwanzspitze ist buschig behaart.[2]
Der Schädel ist groß und breit, verglichen mit dem anderer Makibären. Die Jochbeine, besonders die der Männchen sind ausladend. Ältere Männchen entwickeln einen Scheitelkamm. Die Backenzähne und die Paukenblase sind relativ klein, kleiner als bei Bassaricyon medius und Bassaricyon alleni. Die Eckzähne sind dagegen größer als die anderer Makibären.[1]
Von allen anderen Makibären kann der Mittelamerika-Makibär am einfachsten anhand seiner Färbung unterschieden werden. Er ist graubraun und hat normalerweise ein graues Gesicht, während die anderen Makibären eher bräunlich, teilweise mit einem rötlichen Einschlag, sind.[1]
Der Mittelamerika-Makibär kommt vom nördlichen Nicaragua über Costa Rica bis in die westpanamaische Provinz Chiriquí vor. Einzelne Sichtungen gibt es auch aus Honduras und Guatemala.[2] Dabei kommt er vor allem in immergrünen Regenwaldgebieten und an Waldrändern vor. Die Höhenverbreitung reicht von Meereshöhe bis in Höhen von 2000 Metern, wobei die Hauptverbreitung in Höhen von 1000 bis 1700 Metern liegt. Die östliche Grenze des Verbreitungsgebietes ist noch nicht genau bekannt. Sie liegt zwischen 81 und 80° West in Zentralpanama. Ob der Mittelamerika-Makibär dort Kontakt zu Bassaricyon medius hat, ob die Arten in einem kleinen Gebiet zusammen vorkommen, ob es möglicherweise zu einer begrenzten Hybridisierung kommt oder ob die Verbreitungsgebiete der Arten deutlich getrennt sind, ist bisher unbekannt.[1]
Der Mittelamerika-Makibär ist primär nachtaktiv und lebt vor allem in den höheren Bereichen des Waldes im Laub der Bäume. Nach Ansicht einzelner Wissenschaftler meidet er anthropogen beeinflusste Gebiete,[2] andere beschreiben eine gute Anpassung an Sekundärwälder und Plantagen.
Er ernährt sich überwiegend von Früchten, vor allem von Feigen, und kann sehr häufig in früchtetragenden Bäumen beobachtet werden. Daneben soll er auch Insekten und kleine Wirbeltiere erbeuten[3] wobei Prange & Prange 2009 dies als Gerücht darstellen. Dokumentiert ist der Fall eines Schlankbären im Biologischen Reservat Monteverde, Costa Rica, der ein Bunthörnchen (Sciurus variegatoides) gefangen und getötet hat. Ein weiterer Schlankbär soll regelmäßig Kolibris gefangen haben und ein dritter wurde beobachtet, wie er eine Mexikanische Hirschmaus (Peromyscus mexicanus) gefangen und gefressen hat.[2]
Für Panama wurden insgesamt 15 verschiedene Nahrungspflanzen für den Mittelamerika-Makibären nachgewiesen, zudem wird vor allem zum Beginn der Trockenzeit dem Nektar der Blüten des Balsabaumes (Ochroma pyramidale) eine besondere Bedeutung zugeschrieben.[2]
Zwischen den Mittelamerika-Makibären und dem teilweise im gleichen Lebensraum vorkommenden Wickelbären wird eine starke Konkurrenz um verfügbare Ressourcen, vor allem Nahrungspflanzen und Habitate, angenommen. Man geht davon aus, dass der in einem deutlich größeren Gebiet vorkommende Wickelbär gegenüber den Schlankbären konkurrenzstärker ist und diese entsprechend in Gebiete verdrängt, die nur über begrenzte Ressourcen verfügen.[2]
Der Mittelamerika-Makibär bringt in der Regel ein einzelnes Jungtier nach einer Tragzeit von 2,5 Monaten zur Welt. Die Geburt erfolgt dabei wahrscheinlich zum Beginn der Trockenzeit.[2]
Zu den potenziellen Fressfeinden der Mittelamerika-Makibären gehören vor allem der Jaguarundi (Herpailurus yaguarondi), der Ozelot (Leopardus pardalis) sowie große Schlangen. Die Tayra (Eira barbara) könnte sie ebenfalls erbeuten, wenn sie sich tagsüber in ihre Bauten zurückziehen.[2]
Über Parasiten der Mittelamerika-Makibären liegen nur wenige Informationen vor. Zu den nachgewiesenen Parasiten gehören die Leishmanien Leishmania braziliensis und Leishmania panamensis. Experimentell konnten die Tiere weder mit Isospora arctopitheci noch mit Toxoplasma gondii infiziert werden.
Der Mittelamerika-Makibär wird als anerkannte Art den Makibären der Gattung Bessaricyon zugeordnet, die nach derzeitigem Erkenntnisstand aus vier Arten besteht.[1][3]
Benannt wurde Bassaricyon gabbii nach William M. Gabb, der das erste wissenschaftlich beschriebene Exemplar der Art gefangen hat.[2] Gegenwärtig werden keine Unterarten anerkannt. Im nördlichen Nicaragua sollen die Tiere ein etwas rötlicheres Fall haben als die in Costa Rica oder im westlichen Panama. Sollte diese From als eigenständige Unterart anerkannt werden, so steht der Name Bassaricyon g. richardsoni J.A. Allen, 1908 zur Verfügung. Unter den Namen Bassaricyon lasius Harris, 1932[4] (Harris-Makibär) und Bassaricyon pauli Enders, 1936 (Chiriqui-Makibär) wurden Beschreibungen veröffentlicht, die sich nur in der Fellfarbe und der Haarlänge gering von Bassaricyon gabbii unterschieden. Die Beschreibungen basieren nur auf ein einziges Typusexemplar (Bassaricyon pauli) bzw. die Art ist nur von seinem Erstbeschreibungsort (Terra typica) nahe der Quelle des Rio Estrella im südlichen Cartago in Costa Rica bekannt (Bassaricyon lasius). Beide Formen gelten heute als Synonym von Bassaricyon gabbii.[1]
Die Art wird von der International Union for Conservation of Nature and Natural Resources (IUCN) global aufgrund des relativ großen Verbreitungsgebietes als „nicht gefährdet“ (Least concern) eingeschätzt. Die Art kommt in einer Reihe geschützter Gebiete in ihrem Verbreitungsgebiet vor und kann sich auch nach einer Veränderung des Lebensraumes gut an neue Lebensbedingungen anpassen. Als Hauptbedrohung für einzelne Populationen wird der Lebensraumverlust durch Entwaldung angesehen. Eine Bejagung der Art findet nicht statt, allerdings werden lokal die Jungtiere gefangen und als Haustiere verkauft.[5]
Der Mittelamerika-Makibär (Bassaricyon gabbii), auch Schlankbär, Olingo oder Buschschwanz-Olingo genannt, ist eine Art der zu den Kleinbären gehörenden Makibären (Bassaricyon) aus Mittelamerika. Die Art ist die bekannteste Art der Makibären und wird auch von Touristen relativ oft im Biologischen Reservat Monteverde und in anderen Schutzgebieten in Costa Rica gesehen.

The northern olingo (Bassaricyon gabbii), also known as the bushy-tailed olingo or as simply the olingo (due to it being the most commonly seen of the species),[2] is a tree-dwelling member of the family Procyonidae, which also includes raccoons. It was the first species of olingo to be described, and while it is considered by some authors to be the only genuine olingo species,[3] a recent review of the genus Bassaricyon has shown that there are a total of four olingo species, although two of the former species should now be considered as a part of this species.[2] Its scientific name honors William More Gabb, who collected the first specimen.[4][5] It is native to Central America.[2]
The northern olingo is a slender arboreal animal, with hind legs distinctly longer than the fore legs, and a long, bushy tail. The face is short and rounded, with relatively large eyes and short round ears.[6] The fur is thick and colored brown or grey-brown over most of the body, becoming slightly darker along the middle of the back, while the underparts are light cream to yellowish.[6] A band of yellowish fur runs around the throat and sides of the head, where it reaches the base of the ears, while the face has greyish fur. The tail is similar in color to the body, but has a number of faint rings of darker fur along its length. The soles of the feet are hairy, and the toes are slightly flattened, ending with short, curved claws.[6] Females have a single pair of teats, located on the rear part of the abdomen, close to the hind legs.[4]
Adults have a head-body length of 36 to 42 centimetres (14 to 17 in), with a 38 to 48 centimetres (15 to 19 in) tail.[6] They weigh around 1.2 to 1.4 kilograms (2.6 to 3.1 lb).[6] The northern olingo possesses a pair of anal scent glands,[6] capable of producing a foul-smelling chemical when the animal is alarmed.[4]
This is the largest of the olingo species.[2] Its pelage is typically less rufous than the other olingos, while its tail bands are a bit more distinct.[2]
The northern olingo is found from Nicaragua through Costa Rica and western Panama.[2] It has also been reported from Honduras and Guatemala, although its great similarity to other olingos, and to kinkajous, may make such reports suspect, and they are not currently recognised by the IUCN.[1] While some individuals have been found as low as sea level,[2] it typically inhabits montane[2] and tropical moist forests[4] from 1,000 metres (3,300 ft)[2] up to around 2,000 metres (6,600 ft) elevation, although it apparently avoids plantations and areas of secondary forest.[4]
Previously, three subspecies (including the nominate) were recognized of this olingo: B. g. gabbii, B. g. richardsoni, and B. g. medius.[3] The recent review of the genus has made several changes to the definition of this species:
The closest relatives of B. gabbii are the two lowland olingo species of Panama and northwestern South America, B. alleni and B. medius, from which it diverged about 1.8 million years ago.[2]
The northern olingo is a nocturnal herbivore, feeding almost entirely on fruit, especially figs. It has been observed to drink the nectar of balsa trees during the dry season, and, on rare occasions, to pursue and eat small mammals, such as mice and squirrels. During the day, it sleeps in dens located in large trees.[4] It has an estimated home range of around 23 hectares (57 acres).[7]
Although it has been considered to be a solitary animal, it is often encountered in pairs, and may be more sociable than commonly believed. It is arboreal, spending much of its time in trees. Its tail is not prehensile, unlike that of the related kinkajous, although it can act as a balance.[4] The call of the northern olingo has been described as possessing two distinct notes, with a "whey-chuck" or "wey-toll" sound.[7]
The northern olingo has a diet and habitat similar to those of kinkajous, and, when resources are in short supply, the larger animal may drive it away from its preferred trees.[7] Predators known to feed on the northern olingo include the jaguarundi, ocelot, tayra, and several boas. It is believed to breed during the dry season, and to give birth to a single young after a gestation period of around ten weeks. It has lived for up to twenty-five years in captivity.[4]

L'olingo de Chiriquí (Bassaricyon pauli) est une espèce d'olingo vivant en Amérique du Sud, tout du moins au Panama.
L'olingo comune (Bassaricyon gabbii J. A. Allen, 1876), noto anche come olingo di Gabb, è un procionide del genere Bassaricyon originario dell'America centrale. È la più conosciuta delle quattro specie di olingo e viene avvistato relativamente di frequente dai turisti nella riserva biologica di Monteverde e in altre aree protette della Costa Rica[2].
L'olingo comune è il rappresentante più grande del suo genere. Ha un corpo snello con zampe anteriori relativamente corte e zampe posteriori leggermente più lunghe. Misura complessivamente circa 78-97 centimetri di lunghezza, dei quali circa 40-52 costituiti dalla sola coda. La lunghezza della coda è 0,9-1,2 volte pari alla lunghezza testa-tronco: rispetto alla lunghezza testa-tronco, la coda è quindi più corta di quella delle altre tre specie di olingo. Il peso varia tra 1,1 e 1,58 chilogrammi[2].
La pelliccia è spessa e morbida. Il suo colore va dal marrone al grigio-brunastro, raramente marrone dorato, con il lato ventrale color crema più chiaro, a volte con una sfumatura arancione. La pelliccia è solitamente più scura lungo la linea centrale del dorso e presenta una fascia giallastra che si estende dalla nuca fino alle orecchie. La faccia è larga e più grigia del corpo, il muso è corto e appuntito. Gli occhi sono grandi e presentano un'iride color cannella e pupille verticali e strette. Le orecchie sono arrotondate e misurano tra 2,5 e 4,4 centimetri di lunghezza[2][3].
I piedi sono larghi e dotati di artigli ricurvi: quelli posteriori sono lunghi circa 6,5-10 centimetri. A differenza del cercoletto (Potos flavus), con cui viene spesso confuso, l'olingo comune non ha la coda prensile. Essa è leggermente appiattita dorsoventralmente e può avere da 11 a 13 anelli. L'estremità è folta e pelosa[3].
Il cranio è grande e largo rispetto a quello degli altri olingo. Le ossa zigomatiche, specialmente quelle dei maschi, sono particolarmente ampie. I maschi più anziani sviluppano una cresta sagittale. I denti posteriori e la bolla timpanica sono relativamente piccoli, più che in Bassaricyon medius e Bassaricyon alleni. I canini, d'altra parte, sono più grandi di quelli degli altri olingo[2].
L'olingo comune si può distinguere facilmente dagli altri olingo per il suo colore: è grigio-brunastro e di solito ha la faccia grigia, mentre i congeneri sono più marroncini, talvolta con una sfumatura rossastra[2].
L'olingo comune è diffuso dal nord del Nicaragua, attraverso la Costa Rica, fino alla provincia panamense occidentale di Chiriquí. Sono stati registrati singoli avvistamenti anche in Honduras e Guatemala[3]. Si incontra principalmente nelle foreste pluviali sempreverdi e ai loro margini. La sua distribuzione altitudinale va dal livello del mare ad altitudini di 2000 metri, ma è più frequente nella fascia compresa tra 1000 e 1700 metri. Il limite orientale dell'areale non è ancora noto con esattezza: si trova tra gli 81 e gli 80 gradi ovest nel centro di Panama. Inoltre non è ancora noto se in questo punto l'olingo comune abbia contatti con Bassaricyon medius, se le due specie siano presenti entrambe in una piccola area, se vi possano essere casi limitati di ibridazione o se i loro areali siano chiaramente separati[2].
L'olingo comune è principalmente notturno e vive soprattutto negli strati superiori della foresta, tra le chiome degli alberi. Secondo alcuni scienziati eviterebbe le zone influenzate dall'uomo[3], altri ritengono che sia ben adattato a vivere in foreste secondarie e piantagioni.
Si nutre principalmente di frutta, in particolare di fichi, e si può avvistare facilmente sugli alberi da frutto. Inoltre, si ritiene che catturi anche insetti e piccoli vertebrati[4], ma Prange e Prange, 2009 sostengono che si tratti solo di dicerie. È documentato il caso di un olingo della riserva biologica di Monteverde, in Costa Rica, che catturò e uccise uno scoiattolo variegato (Sciurus variegatoides). Si dice che un altro esemplare abbia catturato regolarmente dei colibrì e che un terzo sia stato visto catturare e mangiare un peromisco messicano (Peromyscus mexicanus)[3].
A Panama sono state identificate in tutto 15 specie diverse di piante che forniscono cibo all'olingo comune; il nettare dei fiori dell'albero di balsa (Ochroma pyramidale) è particolarmente apprezzato all'inizio della stagione secca[3].
Si ipotizza una forte competizione per le risorse disponibili, soprattutto piante alimentari e habitat, tra gli olingo comuni e i cercoletti, che a volte vivono nello stesso habitat. Si presume che il cercoletto, che occupa un areale molto più ampio, sia maggiormente competitivo dell'olingo e che di conseguenza lo costringa a spostarsi verso aree dove le risorse sono limitate[3].
L'olingo comune di solito dà alla luce un unico piccolo dopo un periodo di gestazione di 2,5 mesi. Il parto ha luogo probabilmente all'inizio della stagione secca[3].
Tra i potenziali predatori dell'olingo comune vi sono lo yaguarondi (Herpailurus yagouaroundi), l'ocelot (Leopardus pardalis) e i grandi serpenti. Il tayra (Eira barbara) potrebbe dare la caccia agli olingo anche quando si ritirano nelle loro tane durante il giorno[3].
Riguardo ai parassiti dell'olingo comune sono disponibili solo poche informazioni. Tra quelli rilevati finora vi sono le leishmanie Leishmania braziliensis e L. panamensis. In via sperimentale questa specie non è potuta essere infettata né da Isospora arctopitheci né da Toxoplasma gondii.
L'olingo comune appartiene al genere Bassaricyon, che comprende in tutto quattro specie[2][4].
Bassaricyon gabbii prende il nome da William M. Gabb, che catturò il primo esemplare della specie descritto scientificamente[3]. Attualmente non viene riconosciuta nessuna sottospecie. Si dice che gli esemplari del nord del Nicaragua abbiano una pelliccia più rossastra rispetto a quelli della Costa Rica o della parte occidentale di Panama. Quando la popolazione in questione viene trattata come sottospecie indipendente riceve il nome di Bassaricyon. g. richardsoni J. A. Allen, 1908. Sotto il nome di Bassaricyon lasius Harris, 1932[5] (olingo di Harris) e Bassaricyon pauli Enders, 1936 (olingo di Chiriquí) sono stati descritti degli esemplari che differivano solo leggermente da Bassaricyon gabbii in termini di colore del mantello e lunghezza del pelo. Tali descrizioni si basano su un unico esemplare tipo (Bassaricyon pauli) oppure la presunta specie è nota solo nel luogo della sua prima descrizione (terra typica), vicino alla sorgente del Rio Estrella nella parte meridionale della provincia di Cartago nella Costa Rica (Bassaricyon lasius). Entrambe le forme vengono oggi considerate sinonimo di Bassaricyon gabbii[2].
L'olingo comune viene classificato dall'Unione internazionale per la conservazione della natura (IUCN) come «specie a rischio minimo» (Least Concern) grazie alla sua area di distribuzione relativamente ampia. La specie è presente in alcune aree protette del suo areale e può adattarsi bene a nuove condizioni di vita anche dopo un cambiamento di habitat. La perdita dell'habitat dovuta alla deforestazione è considerata la principale minaccia per le singole popolazioni. La specie non viene cacciata, ma i giovani vengono catturati e venduti localmente come animali domestici[1].

Ziemeļu olings, arī kuplastes olings (Bassaricyon gabbii) ir neliels, kokos dzīvojošs jenotu dzimtas (Procyonidae) kinkažuveidīgs plēsējs, kas pieder olingu ģintij (Bassaricyon). Ziemeļu olings mājo Centrālamerikas lietus mežos. Lai arī tas sastopams jau no jūras līmeņa, tomēr biežāk olings apmetas kalnos no 1000 līdz 2000 metriem virs jūras līmeņa.[1] Tas sastopams Nikaragvā, Kostarikā un Panamas rietumos, kā arī tā novērojumi ir reģistrēti Hondurasā un Gvatemalā.[2] Tomēr olings ārēji ir ļoti līdzīgs pārējām olingu sugām un kinkažu, tādēļ Starptautiskā dabas un dabas resursu aizsardzības savienība (IUCN) šos vērojumus pagaidām nav atzinusi.[1]
Ziemeļu olinga tuvākie radinieki ir divas ieleju olingu sugas no Panamas un Dienvidamerikas ziemeļrietumiem (ielejas rietumu olings (Bassaricyon medius) un ielejas austrumu olings (Bassaricyon alleni)), no kurām ziemeļu olings atdalījās pirms apmēram 1,8 miljoniem gadu.[2]
Šī ir pirmā olingu suga, kas tika identificēta un aprakstīta. Ilgu laiku valdīja uzskats, ka tā ir vienīgā. Ar laiku tika atzītas 5 olingu sugas, bet 2013. gadā, balstoties uz jaunākajiem morfoloģiskajiem un ģenētiskajiem pētījumiem, tika veiktas izmaiņas olingu ģintī. Vairākas līdz tam atsevišķas sugas (Bassaricyon lasius un Bassaricyon pauli) tika apvienotas ar divām kuplastes olinga pasugām (B. g. gabbii, B. g. richardsoni) un izveidota ziemeļu olinga suga, bet Dienvidamerikā dzīvojošā kuplastes olinga pasuga (Bassaricyon gabbii medius) kļuva par atsevišķu sugu - ielejas rietumu olingu (Bassaricyon medius).[2]
Ziemeļu olings ir neliela, slaida auguma plēsējs ar garu, kuplu asti, kas ir garāka par ķermeni. Tā pakaļkājas ir ievērojami garākas nekā priekškājas. Seja ir apaļa ar īsu purnu, lielām acīm un īsām, noapaļotām, plati novietotām ausīm. Kažoks biezs un mīksts, krāsa brūna, dzeltenbrūna vai pelēkbrūna, pavēdere gaiša.[3] Astes matojumā var saskatīt gredzenveida krāsojumu. Pēdas matotas ar viegli saplacinātajiem pirkstiem, kuriem ir ļoti asi nagi. Ziemeļu olings ir lielākais no visiem olingiem, tā ķermeņa garums ir 35—47 cm, astes garums 40—52 cm, svars 1,13—1,58 kg.[2] Abi dzimumi ir apmēram vienā augumā.[4] Ziemeļu olingam zem astes ir pāris ar anālajiem dziedzeriem, no kuriem briesmu gadījumos izdalās asi smirdīgs sekrēts.[5]
To bieži jauc ar kinkažu. Visvieglāk tos var atšķirt pēc astes. Kinkažu ir tvērējaste, bet olingam astei nav tvērējastes īpašības un tā tiek izmantota, lai noturētu līdzsvaru koku zaros. Arī purns olingam ir garāks kā kinkažu.[5]
Ziemeļu olings pamatā uzturas kokos, ļoti reti nokāpjot uz zemes. Kokā tas ir neticami veikls un bez grūtībām pārlec no zara uz zaru līdz 3 metriem.[6] Tas ir aktīvs nakts laikā. Pa dienu tas guļ savā migā, kas iekārtota liela koka dobumā. Miga tiek izklāta ar sausām lapām.[6] Lai arī ziemeļu olings ir vienpatis, ik pa laikam var novērot olingu pārus vai grupas līdz pat 6 dzīvniekiem. Grupas parasti barojas kādā kokā ar iecienītiem augļiem.[4] Ziemeļu olingi izvairās no kinkažu, kas parasti agresīvi padzen olingus.[4] Ziemeļu olinga dabīgie ienaidnieki ir jaguāri, oceloti, tairas un žņaudzējčūskas.[3]
Ziemeļu olings, lai arī ir visēdājs, tomēr pamatā barojas ar augļiem, ziedu nektāru un pašiem ziediem.[3] Visiecienītākie augļi ir vīģes. Retos gadījumos ziemeļu olings barojas ar kukaiņiem un sīkiem mugurkaulniekiem, grauzējus un putnus ieskaitot.[3]
Ziemeļu olings var vairoties visu gadu, tam nav īpašas pārošanās sezonas. Grūsnība ilgst 73—74 dienas. Piedzimst tikai viens nevarīgs un akls mazulis.[3] Jaundzimušais sver 55 g. Pēc 27 dienām atveras acis un pēc 2 mēnešiem tas sāk ēst pieaugušo dzīvnieku barību. Par mazuli rūpējas tikai māte. Dzimumbriedumu jaunie oplingi sasniedz 21 mēnešu vecumā.[6] Nebrīvē ziemeļu olings dzīvo līdz 25 gadiem.[5]

Gabbi's slankbeer (Bassaricyon gabbii) wordt ook wel olingo, makibeer, bush-bear of martilla genoemd en behoort tot de roofdierfamilie Procyonidae.
Lengte: kop-romp 35-48 cm, staart 38-49 cm. Gewicht: 0,9-1,5 kg.
De olingo vertoont veel gelijkenis met de rolstaartbeer (Potos flavus), maar de olingo is slanker gebouwd en de staart is ook geringd en wolliger. Het lichaam is bedekt met een dikke, zachte vacht die goudkleurig is met zwarte of grijze tinten op de rug en vaalgele op de buik. De zeer lange staart is ruig behaard met onduidelijke ringen. De ronde kop is aan de bovenkant tamelijk vlak. De snuit is lang en spits en de oorschelpen klein en wit van kleur. Dit dier heeft vrij korte poten en gekromde, niet-intrekbare klauwen.
De olingo kan ongeveer 17 jaar oud worden.
Tropische regenwouden en nevelwouden tot op 2000 m hoogte in Latijns-Amerika
Olingo's voeden zich het meest met vruchten en als een boom veel vruchten draagt, treft men er regelmatig een hele groep aan. In zo'n groep bevinden zich vaak ook rolstaartberen, opossums en nachtapen. Ze eten ook insecten en kleine zoogdieren, die worden gevangen na een korte achtervolging. Een olingo kan in een nacht één derde van zijn lichaamsgewicht aan voedsel eten.
De olingo leeft hoofdzakelijk in bomen, alleen of paarsgewijs. Het is een nachtdier en overdag slaapt de olingo in een met gras of bladeren bedekt hol, meestal in een holle boom. Tegen de schemering wordt het dier wakker en begint het de nacht met een goede poetsbeurt. In tegenstelling tot andere leden van de familie gebruiken olingo's hun voorpoten niet tijdens het verzorgen van de vacht. Ze krabben zich met hun achterpoten, gebruiken hun tanden als kam en eindigen met wassen. De jacht vindt vooral plaats in de bomen en de olingo komt maar zelden op de bosbodem. Het is een zeer lenig dier, dat goed kan klimmen en sprongen kan maken van wel drie meter, van boom tot boom. De uitgestrekte staart zorgt dan voor evenwicht. Terwijl de olingo door de bomen trekt, laat hij geurvlaggen achter, maar het is niet helemaal duidelijk of deze dieren dat doen om hun territorium te bepalen, om een partner te vinden of om later de weg terug weer te vinden.
Olingo's kunnen zich op elk moment van het jaar voortplanten en het mannetje blijft bij het vrouwtje tot de jongen geboren worden, waarna ze hem wegjaagt. De draagtijd duurt ongeveer 73 dagen en meestal is er maar één jong per worp.

Bassaricyon gabbii[2][3] är en däggdjursart som beskrevs av J. A. Allen 1876. Bassaricyon gabbii ingår i släktet olingobjörnar och familjen halvbjörnar.[4][5] IUCN kategoriserar arten globalt som livskraftig.[1] Inga underarter finns listade.[4]
Det svenska trivialnamnet Yvsvansad olingo förekommer för arten.[6]
Denna oligobjörn når en kroppslängd (huvud och bål) av 35 till 47 cm och en svanslängd av 40 till 48 cm. Vikten varierar mellan 970 och 1500 g. Arten har en gråbrun päls som är hos några individer lite gulaktig. På svansen förekommer mörka otydliga ringar. Hanar och honor har förutom könsorganen likadant utseende och storlek.[7]
Bassaricyon gabbii förekommer från centrala Nicaragua till Colombia och Ecuador. Arten vistas i låglandet och i bergstrakter där den når 2000 meter över havet. Habitatet utgörs av städsegröna skogar där arten gärna klättrar i trädens övre delar.[1]
Individerna är aktiva på natten och de klättrar främst i växtligheten. De lever ensam eller i mindre flockar med upp till sex medlemmar. Födan utgörs av frukter och nektar samt av insekter och mindre ryggradsdjur som ödlor eller småfåglar och deras ägg. Veckelbjörnen (Potos flavus) som lever i samma region fördriver Bassaricyon gabbii ofta från sitt revir. Däremot utgör primater sällan konkurrenter då de flesta primaterna i området är aktiva på dagen.[7]
Bassaricyon gabbii har doftkörtlar när sin anus och markerar olika platser med körtelvätska. Syftet med denna gärning är inte helt utrett.[7]
Honor kan para sig hela året. Dräktigheten varar cirka 74 dagar och sedan föds ett ungdjur som i början är blind. Ungen öppnar ögonen efter ungefär fyra veckor och cirka två månader efter födelsen börjar den med fast föda. Några dagar senare slutar modern med digivning. Fadern deltar troligen inte i ungens uppfostring. Vid slutet av andra levnadsåret blir ungen könsmogen.[7]
I naturen blir individer sällan äldre än 10 år. Med människans vård kan Bassaricyon gabbii leva 25 år. Artens naturliga fiender utgörs av större kattdjur som jaguaren och av större ormar.[7]
