Den rødstrubede vendehals er ikke en trækfugl, men lever hele året rundt i Afrika syd for Sahara. Her lever fuglen på savannen, hvor den yngler i huller i gamle træer. Hullerne kan være blevet lavet af andre fugle.
The red-throated wryneck (Jynx ruficollis), also known as the rufous-necked wryneck or red-breasted wryneck, is a species of wryneck in the woodpecker family closely related to the Eurasian wryneck. Its three subspecies are resident in much of sub-Saharan Africa in open habitats with some trees. It is a slim, elongated bird about 19 cm (7.5 in) in length, with a small head, fine bill, long fan-shaped tail and cryptic plumage intricately patterned in greys and browns. The sexes look similar, although males are slightly larger. The diet of the adults and young is almost entirely ants at all stages of their life cycles. The call of the red-throated wryneck is a series of repeated harsh, shrill notes. When threatened, a bird will twist its neck and head in a snake-like manner while making a hissing sound, presumably to deter predators.
The red-throated wryneck nests in pre-existing holes, usually in trees, preferring old barbet or woodpecker nests. The unlined nest cavity is usually 3–4 m (10–13 ft) above the ground, and the clutch is typically three or four white eggs, laid at one-day intervals. Both sexes incubate the eggs for 12–15 days until the blind, naked chicks hatch. The chicks are fed by both adults for 25–26 days until they fledge. There are usually two broods. The red-throated wryneck has a very extensive range, and its population is large and increasing. For this reason, it is evaluated as a species of least concern by the International Union for Conservation of Nature (IUCN).
The woodpeckers are an ancient bird family consisting of three subfamilies, the wrynecks, the piculets and the true woodpeckers, Picinae. DNA sequencing and phylogenetic analysis show that the wrynecks are a sister clade to other woodpeckers including the Picinae and probably diverged early from the rest of the family.[2]
The wryneck subfamily Jynginae has one genus, Jynx, introduced in 1758 by Swedish naturalist Carl Linnaeus in the 10th edition of his Systema Naturae.[3] It contains two species, the Eurasian wryneck, J. torquilla, and the red-throated wryneck, J. ruficollis. The two wrynecks form a superspecies that probably separated early in their evolution from the piculets,[2] although there has subsequently been only limited divergence between the Jynx species.[4][5]
The red-throated wryneck was first identified by German ornithologist Johann Georg Wagler in 1830.[6][7] It is also known as the rufous-necked wryneck or red-breasted wryneck.[8] The genus name Jynx is from the Ancient Greek name for the Eurasian wryneck, ιυγξ, iunx, and ruficollis is from the Latin rufus, "rufous" and collum "neck".[9] The English "wryneck" refers to the habit of birds in this genus of twisting and writhing their necks when agitated. It was first recorded in 1585.[10]
The red-throated wryneck has three subspecies:[4][11]
The woodpecker family appears to have diverged from other Piciformes about fifty million years ago,[2] and a 2017 study considered that the split between Jynx and other woodpeckers occurred about 22.5 million years ago.[14] A fossil dating from the early Miocene, more than twenty million years ago, consisting of the distal end of a tarsometatarsus had some ‘’Jynx’’-like features, but was classed as an early piculet.[15] By the (Pliocene five million years ago) woodpeckers were similar to those now extant. Fossil wrynecks are known from Europe in the Pleistocene, between 2.6 million and 11,700 years ago.[2]
The red-throated wryneck grows to about 19 cm (7.5 in) in length. The sexes are very similar in appearance, and cannot be distinguished in the field, but the male averages 2–3% larger than the female, has a shorter tail, and is heavier at 52–59 g (1.8–2.1 oz) against her 46–52 g (1.6–1.8 oz).[7][11] It is a slim, elongated bird with a small head, fine bill, long fan-shaped tail and a body shape unlike that of a typical woodpecker.[16]
The overall impression is of cryptic plumage patterned with greys, browns and black.[16] The upperparts and head are brown, barred and mottled in dark shades, and the rump and upper tail coverts are grey with speckles of brown and black. The chin, throat and breast of the subspecies Jynx ruficollis ruficollis are red, and the lower breast and belly are white with some dark streaks; there is a cinnamon tint to the flanks and the underneath of the tail. The wings are brown above and more buff-toned below. The grey bill is long and thin, the irides are chestnut, and the legs are grey.[7] As with all woodpeckers, the first and fourth toes point backwards and the second and third point forwards, a good arrangement for clinging to vertical surfaces.[17] Young birds resemble adults after 20 days, but are darker and more barred above, and lightly barred below with a smaller and darker red patch.[4]
The three subspecies differ in appearance, mainly in the extent of red on the breast. In Jynx ruficollis ruficollis the red extends from the chin to the chest, whereas in J. r. aequatorialis it extends further down the breast, and there is a more cinnamon tinge to the flanks. J. r. pulchricollis has a brown-barred white chin and upper throat, and its red patch is darker and confined to its lower throat and upper breast. This race also has more rufous upperparts.[4]
The two wrynecks cannot be confused with any other species, but some Eurasian birds may winter within the range of red-throated wryneck.[16] The African species, compared to its migratory cousin, differs in its usually obvious red throat, larger size, overall browner appearance and the lack of a dark streak through the eye.[7]
Most woodpeckers have only one moult as soon as breeding has finished, but wrynecks have a partial moult prior to breeding, and also replace their tail feathers in a different sequence from true woodpeckers since they have no need to retain central tail feathers for support, as is required by their arboreal relatives.[18] Details of the moult can be complex and variable, and ageing wrynecks from their plumage appearance can be challenging.[19]
The call of the red-throated wryneck is a series of repeated harsh, shrill notes kweek-kwik-kwee-quee, usually slower than the call of the Eurasian wryneck. It is a far-carrying territorial call given from a prominent perch. There is also a peegh alarm call followed by a repeated harsh krok. Young in the nest make wheezing squeaks initially, later a repeated buzzing tsch.[4] There is a quiet "click" call given as an alarm or pre-roosting. All calls are given by both sexes, but the male's kweek call is lower pitched than that of the female.[5]
Wrynecks do not drum like woodpeckers, but may tap near the nest hole or on branches,[4] apparently as a displaced aggression activity during interactions between two birds.[5]
The rufous-necked wryneck has a distribution confined to sub-Saharan Africa.[4] It occurs in about 20 countries in disjunct areas ranging from Nigeria, Cameroon, Central African Republic and Ethiopia in the north down to South Africa and Eswatini in the south.[1] It is not truly migratory, although there may be local movements and post-breeding dispersal.[20] It is a vagrant to Sudan, South Sudan and Zimbabwe, and an occasional non-breeding visitor to Lesotho.[11]
The typical habitat is open grassland with trees, particularly acacia and also miombo woodlands, but it is also found in other semi-open woodland, such as forest edges and clearing. It will use man-made habitats such as farmland, parks and gardens as long as there are trees present, which can include introduced eucalyptus and conifers.[4]
It occurs at altitudes from 600 metres (2,000 ft) to 3,300 metres (10,800 ft). It is found up to 1,550 metres (5,090 ft) in South Africa and mainly between 1,400–2,500 metres (4,600–8,200 ft) in Kenya.[11]
The red-throated wryneck normally perches upright on a branch with its tail and wings pointing vertically down and its head pulled into its shoulders, although when it calls it raises its head and stretches its neck out. When displaying at another wryneck, it leans forward with its tail pointing vertically upright and its bill raised while it calls loudly and sways from side to side.[5] Like its Eurasian cousin, when threatened the red-throated wryneck will twist its neck and head in a snake-like manner while making a hissing sound, presumably to deter predators.[21]
Wrynecks fly by alternating powered flaps with glides on closed wings, giving the bouncing flight appearance typical of woodpeckers.[5]
Pairs of wrynecks are territorial, particularly in the breeding season, one study showing territory sizes from 8–24 hectares (20–59 acres), mean 17 hectares (42 acres). All territories included clumps of trees. Territories are advertised throughout the year by calling from prominent perches, mainly by the male.[5]
The red-throated wryneck feeds almost entirely on ants, their larvae, pupae and eggs, although termites and other small invertebrates are occasionally taken, prey items being gleaned with its long sticky tongue. The young are fed the same mostly ant-based diet. This wryneck is a solitary feeder, and 90% of its foraging is on the ground, probing into ant hills. When birds feed in trees, they pick prey off the vegetation but do not excavate.[20][8]
As with the Eurasian species, the red-throated wryneck nests in pre-existing holes, usually in trees. They do not excavate cavities themselves, but they may enlarge a hole if the wood is soft enough; no nesting material is added. Old barbet and woodpecker nests are preferred, although holes in fence posts and nest boxes are also used. The wryneck competes with other species for suitable sites, notably the crested barbet.[20] The nest is usually 3–4 m (10–13 ft) above the ground, with a cavity that is typically 300 mm (12 in) deep, and at least 300 m (980 ft) from neighbouring nests.[11] Nests may be reused in subsequent years, in one case in alternation with a pair of violet-backed starlings, and also as winter roosts.[5]
The clutch is between one and five, usually three or four, cream-white eggs, laid at one-day intervals. They measure 22 mm × 16.5 mm (0.87 in × 0.65 in) and weigh about 3.25 g (0.115 oz). Both sexes incubate the eggs for 12–15 days until hatching.[11] The chicks are initially pink, naked and blind, but after about eight days their eyes open, and their feathers are growing.[5] The chicks are fed by both adults for 25–26 days until they fledge; they hiss and make snake-like head movements if intruders visit the nest.[11] There are usually two broods, although up to four have been recorded. The young become independent about two weeks after fledging. The timing of breeding varies across Africa, nesting taking place somewhere in every month except June and July.[20] In South Africa, 57% of nests were successful and 40% of eggs produced fledged young.[11]
A single claim of hybridisation between the two Jynx wrynecks reported from Cameroon was subsequently considered to be an aberrant red-throated wryneck.[22]
The red-throated wryneck is a host of at least two Ischnoceran lice, Penenirmus serrilimbus and Brueelia straminea,[23][24] and the Leucocytozoon L. sqamatus.[25]
The wryneck's nests are visited by brood parasitic honeyguides, especially the lesser honeyguide.[11] The adult honeyguide does not remove the host's eggs or chicks, but its monitoring of active nests may attract other predators. Once it has hatched, the honeyguide nestling will kill the host chicks.[26] Chicks may also be killed if a crested barbet pair take over a wryneck nest for their own use.[5]
Although the two wrynecks breed or winter over much of Europe, Asia and Africa, their predators have been little studied outside the European breeding range of Jynx torquilla, where nests may be raided by snakes for eggs and young, and the main avian threat to adult wrynecks is Accipiter hawks.[27]
The red-throated wryneck has an extremely large range, and its population is large and increasing. For this reason, it is evaluated as a species of least concern by the International Union for Conservation of Nature. In South Africa it is locally common, and the range has expanded due to introduction of non-native trees to formerly unwooded grassland areas.[1][11]

Ruĝgorĝa koltordulo estas birdo de genro Koltordulo, kiu loĝas en Afriko.
Nur du specioj formas tiun genron. La alia estas la disvastigata eŭrazia koltordulo. Ĝi estas iomete pli granda ol la samgenra eŭrazia koltordulo. Koloro de plumaro estas simila, kiel ĉe eŭrazia koltordulo – kamufla kun komplika bildo de brunaj kaj grizaj koloroj. Nur mentono, gorĝo, brusto (parte) kaj parto de flugilaj plumoj estas kolorigitaj malsame - ruĝe aŭ ruĝece. Krome la dorso estas pli bruna (kun nigraj makuletoj) kaj la ŝultroj kaj kapo pli grizecaj, dum subaj partoj (ventro kaj subvosto) pli flavecaj kun vertikalaj mallarĝaj strioj.
Vivas ĝi nur en Afriko izole en kelkaj separitaj areoj sude de Saharo: de Gabono kaj Kameruno okcidente al Etiopio oriente kaj ĝis Sudafrika Respubliko. La birdo estas nemigrata.
Pro insuleca teritoria troviĝo oni kreas tri subspeciojn, kiuj malsamas en koloro de plumaro (per pli granda, malpligranda aŭ manko de la ruĝbruna koloro) ĉefe sur mentono, brusto kaj gorĝo.
Tiu afrotropisa birdo loĝas en malferma kamparo (savano), en pli maldensaj arbaroj, je la randoj de arbaroj. Ĝi ne ĉizas nestkavojn sed serĉadas lasitajn kavojn en maljunaj arboj post pegoj aŭ birdoj de parenca familio Capitonidae.
La voĉo estas nazeca.

Le Torcol à gorge rousse (Jynx ruficollis) est une espèce d'oiseaux de la famille des Picidae.
Sarkankakla tītiņš (Jynx ruficollis) ir maza auguma dzilnu dzimtas (Picidae) putnu suga. Izdala trīs pasugas.[1][2] Lai arī sarkankakla tītiņa izplatības areāls ir ļoti plašs, tam ir vairākas izolētas populācijas, kas dzīvo Āfrikas centrālajā daļā un dienvidos.[3] Sarkankakla tītiņš mājo savannā, kur aug veci koki un kuros ir dzeņu vai bārdaiņu izveidoti dobumi ligzdošanai.
Sarkankakla tītiņa izplatības areāls ir ļoti plašs. Tas sastopams Angolā, Burundi, Kamerūnā, Centrālāfrikas Republikā, Kongo Republikā, Kongo Demokrātiskajā Republikā, Etiopijā, Gabonā, Kenijā, Lesoto, Mozambikā, Nigērijā, Ruandā, Dienvidāfrikā, Svazilendā, Tanzānijā, Ugandā un Zambijā.[3] Lai arī trūkst datu par sugas populācijas lielumu, suga šobrīd netiek uzskatīta par apdraudētu.[3]
Sarkankakla tītiņš ir neliela auguma putns, bet, salīdzinot ar Eirāzijā dzīvojošo tītiņu, tas ir nedaudz lielāks. Sarkankakla tītiņa ķermeņa garums ir apmēram 19 cm, svars tēviņiem 52—59 g, mātītēm 46—52 g.[4] Ārēji tas vairāk atgādina dažus zvirbuļveidīgos putnus, nekā dzilnveidīgos. Tas ir slaids, rudibrūni raibs. Mugurpuse ir pelēkāka un tumšāka nekā vēderpuse, kas ir samērā gaiša. Uz rīkles, krūšu augšpusē un zemastē tam ir koši ruds apspalvojums, kas kontrastaini nodalās no gaišākā vēdera apspalvojuma. Uz rīkles ir tumšākas šķērssvītru joslas, bet uz vēdera vertikālas garenjosliņas.[4] Knābis ir pelēkbrūns ar tumšāku galu, acis brūnas. Sarkankakla tītiņam ir pagarš kakls, kuru tas uztraukumā izloka, grozot galvu un šņācot kā čūska, kā arī satraukumā tas uzbož cekulu. Abi dzimumi izskatās vienādi. Jaunajiem putniem rudā rīkle ir pelēcīgāka, mugura tumšāka un raibāka.[4]
Kā visiem dzilnveidīgajiem sarkankakla tītiņa pēdām divi vidēji pirksti ir vērsti uz priekšu, bet abi malējie uz atpakaļu, kas nodrošina putniņam spēju staigāt vertikāli pa koka stumbru.[5] Sarkankakla tītiņam, tāpat kā citām dzilnām un dzeņiem, mēle ir lipīga un lidojums ir viļņveidīgs. Tā astes spalvas nav stīvas kā citiem dzilnveidīgajiem, tādēļ tas vairāk uzturas koku zaros, nekā uz stumbriem.
Sarkankakla tītiņš sastopams savannas mežos, atklātā savannā un mežmalās. Tas ir ļoti parasts ligzdotājs sausajos akāciju mežos un krūmājos upīšu krastos. Tas ir arī bieži sastopams apdzīvoto vietu tuvumā un kultivētos dārzos. Sarkankakla tītiņš mājo reģionos, kas ir 600—3000 metrus virs jūras līmeņa. Kenijā tas sastopams no 1400—2500 metriem virs jūras līmeņa.[4] Sarkankakla tītiņi pamatā ir nometnieki, bet reizēm tie klejo.[4]
Sarkankakla tītiņš galvenokārt barojas ar skudrām un to kāpuriem, bet tas barojas arī ar citiem nelieliem posmkājiem. Barību meklē uz koku stumbriem, trupējošos kokos un uz zemes, kur tas pārvietojas ar īsiem lēcieniem.[4]
Riesta laikā sarkankakla tītiņa tēviņš izrāda uzmanību mātītei, to barojot, arī perēšanas laikā tēviņš baro mātīti. Tā kā tītiņi paši dobumus nekaļ, tie ligzdošanai piemeklē jau gatavus dobumus vai putnu būrīšus. Dējumā ir 3—4 olas, reizēm līdz sešām. Inkubācijas periods ilgst 12—15 dienas, perē abi vecāki, kā arī par mazuļiem rūpējas abi vecāki. Jaunie putni tiek baroti ar skudrām un to oliņām. Ļoti bieži sezonā ir divi perējumi.[4]
Sarkankakla tītiņam ir 3 pasugas:[2]

De Afrikaanse draaihals (Jynx ruficollis) is een specht uit de familie Picidae.
Hij is te herkennen aan de roodbruine vlek onder zijn keel en op de borst. De bovendelen zijn bruin met zwarte spikkels. Hij laat vaak zijn roep horen, een hoog kek-kek-kek-kek. De soort wordt ongeveer 18 centimeter lang.
De Afrikaanse draaihals is een bewoner van savannes, waar hij nestelt in oude nestholtes van andere spechten of Afrikaanse baardvogels. Hij foerageert in bomen waarvan de schors uiterlijk overeenkomt met zijn verenkleed. De Afrikaanse draaihals heeft onder andere de voorkeur voor de zwarte wattle (Acacia mearnsii), een ingevoerde acaciaboom uit Australië die algemeen voorkomt in veel delen van Afrika.
Deze soort komt voor in Afrika ten zuiden van de Sahara. Hij houdt van gevarieerd bosachtige streken, maar komt ook in de buitensteden voor.
De soort telt drie ondersoorten:
Rustvendehals (Jynx ruficollis) er ein spettefugl som lever i Afrika sør for Sahara. Han er ein av to artar i ei biologisk slekt av vendehalsar, den andre arten er den euroasiatiske vendehalsen vendehals, J. torquilla.
Dette er ein liten, litt slank og langhala spettefugl på om lag 19 centimeter i kroppslengd og med vekt på frå 46 til 59 gram, hannar er større enn hoer. Elles er kjønna like. Det er definert tre underartar for rustvendehals, to av dei med to merkbare variantar av fjørdrakter.[1]
Nebbet er gråleg i farga, kort, rettpeikande og kvast. Det er mørkare mot spissen. Beina er olivenbrune i farge.[2] Fjørdrakta kan skildrast som mest av alt kamuflerande, med overside frå panna til haletuppen i gråbrunt som er spragla med mørke nyansar. Primærfjørene er sjokoladefarga med raudbrune tverrstriper. Strupen er lys med mørke tverrstriper, brystet raudbrunt i storleik som varierer, undersida er elles kvit som går over i raudbrunt mot undergumpen og har svarte langsgåande striper. Stjerten har mange tynne, svarte tverrstriper, der den euroasiatiske vendehalsen berre har fire tverrstriper. Elles manglar rustvendehalsar den mørke midtstripa som den euroasiatiske arten har.[1]
Utbreiinga for arten er ikkje godt skildra, han lever i mindre og oppstykka, usamanhengande område i delar av Etiopia, Sør-Sudan, Kenya, Tanzania, Uganda, Nigeria, Kamerun, Kongo-Kinshasa til Angola, og i søraustre Afrika inkludert Sør-Afrika.[1] I motsetnad til arten vendehals er rustvendehals ein standfugl. Føda er hovudsakleg maur i alle stadium frå egg. Dei plukkar bytte med den lange tunga, og oftast beitar dei på bakken på noko skogkledde grassletter. Andre habitat er akasiasavannar, plantasjar og hagar.
Dei er holerugarar, har typisk to, men opptil fire ungekull i året, kvart med 3-4 egg. Begge foreldre rugar og tar omsut for ungane.
Populasjonen er ikkje estimert og er trudd å vere aukande. Arten er stadvis vanleg og er klassifisert som globalt livskraftig.[3]

Rustvendehals (Jynx ruficollis) er en spettefugl som sammen med vendehalsen utgjør gruppa vendehalser. I motsetning til vendehals, er ikke rustvendehals en trekkfugl, men lever hele året rundt i Afrika sør for Sahara. Den lever på savanner, hvor den bor i gamle huller i trær som er laget av andre fugler.
Inndelingen følger Taxonomy in Flux og er i henhold til Boyd (2017).[1] Boyd regner med 237 arter fordelt i tre underfamilier, sju tribus og 38 slekter. Det hersker imidlertid uenighet om denne inndelingen. HBW Alive regner med 254 arter i 33 slekter.[2] Andre autoriteter kan ha lignende forskjeller i inndelingen. Norske navn på artene følger Norsk navnekomité for fugl og er i henhold til Syvertsen et al. (2008).[3] Beskrivelser i parentes er ikke offisielle navn. Alle arter har nødvendigvis ikke fått norsk navn.

Pożywienie stanowią mrówki, ich larwy i poczwarki. Wśród zjadanych gatunków odnotowano Pheidole megacephala, Crematogaster castanea, Lepisiota capensis, Acantholepis capensis i Tetramorium setulferum. Zjada także termity[8].
Gniazduje w dziuplach wykutych przez inne ptaki, takie jak wąsal obrożny (Lybius torquatus) i brodal czubaty (Trachyphonus vaillantii), oraz naturalnych otworach w pniu i budkach lęgowych. Okres składania jaj przypada od września do lutego, najczęściej w październiku[8]. W lęgu 3-4 jaja, niekiedy do sześciu. Inkubacja trwa 13-15 dni, wysiadują oba ptaki z pary. Młode karmione są mrówkami, larwami i poczwarkami[4]. Są w pełni opierzone po 25-26 dniach od wyklucia[8].
