Der Spitzschopf-Seidenkuckuck (Coua cristata), auch Spitzschopfcoua oder Hauben-Seidenkuckuck genannt, ist eine auf Madagaskar endemisch vorkommende Kuckucksart der Gattung der Seidenkuckucke (Coua). Die Art umfasst die vier Unterarten C. c. cristata (Linnaeus, 1766), C. c. dumonti (Delacour, 1931), C. c. pyropyga (Grandidier, 1867) und C. c. maxima (Milon, 1950).
Der Spitzschopf-Seidenkuckuck wird etwa 40–44 cm groß. Es gibt keinen Geschlechtsdimorphismus. Die Haube, der Kopfbereich sowie der Hals sind hellgrau gefärbt, der Rücken, die Flügel sowie die langen Steuerfedern grünlich grau bis dunkelgrau. Die Steuerfedern glänzen zudem lila bis blau, die Spitze dieser Federn ist weiß. Der Brustbereich ist hell bis kastanienbraun gefärbt, die Unterseite weiß. Der Orbitalring ist vor dem Auge lila bis blau, hinter dem Auge hellblau gefärbt und schwarz umrandet. Die Füße sind schwarz. Die Unterarten sind teilweise größer als die Nominatform, auch die Haube ist größer. Die weißen Bereiche auf den Steuerfedern sind unterschiedlich groß ausgeprägt. C. c. dumonti und C. c. pyropyga erscheinen blasser, C. c. maxima dunkler als die Nominatform.[1]
Der Spitzschopf-Seidenkuckuck ist wie alle anderen Seidenkuckucke endemisch für Madagaskar. Die Nominatform C. c. cristata kommt dort entlang der Nordküste, C. c. dumonti an der Westküste zwischen Mahajanga und Morondava und C .c. pyropyga an der Süd-Westküste zwischen Morondava und Toliara vor. Die Unterart C. c. maxima ist lediglich aus der Gegend um die Stadt Tolagnaro im Süd-Westen der Insel bekannt. Die Art bewohnt verschiedene Habitate wie Primär- und Sekundärwälder, Savannen oder Mangroven bis zu einer Höhe von 1000 m. Seltener findet man sie in dichten Regenwäldern. Aufgrund der Häufigkeit des Spitzschopf-Seidenkuckucks sowie des großen Verbreitungsgebietes geht die IUCN von keiner Gefährdung der Art aus.[2][3]
Der Spitzschopf-Seidenkuckuck bewegt sich meist in der unteren Baumschicht fort, wo er seine Nahrung vom Stamm und Ästen der Vegetation absammelt. Die Nahrung besteht u. a. aus verschiedenen Insekten, Chamäleons, Geckos, Schnecken, Früchten sowie Baumsäften von Albiziaarten. Kommen gemeinsam mit dem Spitzschopf-Seidenkuckuck Coquerel- oder Rotstirn-Seidenkuckucke vor, weicht er in höhere Baumschichten aus. Der Spitzschopf-Seidenkuckuck ist im Gegensatz zu anderen Kuckucksarten kein Brutparasit. Das Nest wird in Höhen zwischen 4 und 15 m durch beide Elternteile gebaut. Die Jungen werden gemeinsam groß gezogen.[4]
Die Unterart C. c. maxima ist lediglich durch das von Philippe Milon gesammelte Typusexemplar bekannt, in freier Wildbahn wurde sie nicht mehr gesichtet. Die Unterart wird als verschollen bzw. ausgestorben oder als Hybrid angesehen.[5]
Spitzschopf-Seidenkuckucke werden bislang nur in wenigen Zoologischen Gärten gepflegt. Die regelmäßige Zucht gelang bislang nur im Vogelpark Walsrode.[6]

The crested coua (Coua cristata) is a common medium sized bird member of the cuckoo family, Cuculidae.[2] It is endemic to Madagascar,[3] mainly found in the coastal regions of the island.[4] The crested coua is a weak flyer, so it will often be observed hopping from branch to branch in high canopies.[5][6] It is distinguished mainly by its greenish-grey back, its prominent grey head crest, rufous-coloured breast, white abdomen and bright turquoise and blue patches of bare skin around the eyes.[7]
The adult crested coua is a medium-sized bird, averaging between 12 and 17 inches (30 to 44 cm) in length.[8][9] It has a greenish-gray plumage on the back, a white abdomen, rufous-colored chest and brown eyes. Its long tail is purplish-blue with white tips and its bill and beak are black. Its defining characteristics are its prominent grey head crest and, as goes for all couas, its colourful patches of bare skin around the eyes, which is blue and turquoise in crested couas. In flight, it is recognizable from its short rounded wings and long white-tipped tail.[10]
Furthermore, this bird's third toe is reversible, which helps it have a strong grip when hopping around high branches in the canopy. Although they are common birds in their range, they can be hard to see in the wild since their greenish-gray coloration tends to blend with shadows and acting as camouflage.[11] Males and females are similar physically.
Juveniles are comparable to adult crested couas however, they are paler in colour, have a shorter head crest and do not have the characteristic bright blue and turquoise ring around the eye.[12]
Young chicks are altricial, which means they are naked at birth and need full parental attention for their early development.[13] During that time, they have unique red and white "bullseyes" inside their mouth, supposedly used to indicate to their parents where to put the food. This characteristic is thought to be particularly useful at darker hours of the day.[8][9] They also have a dark skin and a reddish bill at that stage.
The crested coua is one of nine living bird species in the subfamily Couinae, which only has one genus, the Coua.[14] These birds are part of the order Cuculiformes, which includes Cuckoos, Turacos and Roadrunners.[2] Couas are a monophyletic group of endemic birds of Madagascar.[3]
Three of the coua species are arboreal (Blue Coua (C. caerulea), Crested Coua (C. cristata) and Verreaux's Coua (C. verreauxi)), and six species are ground dwelling (Coquerel's Coua (C. coquereli), Running Coua (C. cursor), Giant Coua (C. gigas), Red-fronted Coua (C. reynaudii), Red-capped Coua (C. ruficeps) and Red-breasted Coua (C. serriana)).[3]
The crested coua has four subspecies:[2]
Crested couas are endemic to Madagascar and are the most widespread of all couas. Although their population numbers are unknown, their range is thought to be 562,000 sq km along the coast of the island. They are found at altitudes as high as 900m above sea level, but are most commonly seen around altitudes of 700m.
Despite being mostly found in littoral and deciduous forests, their habitats also consist open areas like savannas and brushlands. They will occasionally be found in mangroves and palms as well. Additionally, they usually avoid deciduous shrublands, selecting mainly for mosaics of forests and croplands.[3] As arboreal species, they tend to use forest layers above five meters and they nest, on average, around nine meters from the ground.[5]
Although this species is marked as least concerned due to their stable populations,[15] crested coua's numbers are believed to be constantly declining due to habitat loss, degradation and hunting pressures.[3]
It is mostly hunted by humans for its tasty meat, but its main natural predators are fossas, hawks and eagles.[16]
Despite being capable of flight, crested couas are weak flyers, so they are rather observed restlessly bouncing and between branches in the canopy. Keeping balance with their long tail and grasping branches with their reversible toe, they are able to move quickly and be agile.[17] Secretive, they tend to stay in groups of three to five individuals outside of breeding season. They do not tend to flock, although they sometimes join mixed-species flocks.[18]
They are highly vocal birds and have several different calls that we can hear in the wild.[6] The most commons are “laser gun calls”, which are a series of piercing sounds, and doubled, wooden “touk-touk” sounds.[19] It is also possible to hear calls such as “koa-koa-koa” and “guay-guay-guay-guay-gwuck”.[9][20] Its call can sometimes serve as an indicator of predator presence in the environment.[16]
Couas, like many birds, tend to be more vocal around sunset, often creating mixed chorus with other species.[21] They also raise their head crest while calling.[7]
Breeding crested couas are usually found in monogamous pairs.[13] Unlike some other species of cuckoos, these birds do not take part in brood parasitism, but rather, both male and female co-parent the chicks.[8] The pair builds their nest themselves out of twigs and hide it in trees or bushes to avoid detection by predators. Two single white eggs are laid and incubated by both parents.[22] The chicks are born altricial with both parents equally helping in raising the young until they are about two weeks old, when they leave the nest. Couas have low fecundity, but they have a high adult longevity (up to 15 years in captivity), which is why they can afford to have a smaller brood size. Additionally, because of their short young-rearing period, it is possible for them to have several clutches in one breeding season, which is from September to March.[20]
They have an omnivorous diet consisting of arthropods, fruits, berries, snails, chameleons, leaves, seeds and others. They essentially feed on everything size appropriate that they find in their environment.[20][7]
