The Pacific long-tailed cuckoo (Urodynamis taitensis), also known as the long-tailed cuckoo, long-tailed koel, sparrow hawk, home owl, screecher, screamer or in Māori, is a species of the Cuculidae bird family (the cuckoos). It is a migratory bird that spends spring and summer in New Zealand, its only breeding place, and spends winter in the Pacific islands. It is a brood parasite, laying its eggs in the nests of other bird species and leaving them to raise its chicks. Taxonomy Urodynamis taitensis is most closely related to the channel-billed cuckoo (Scythrops novaehollandiae), which lives in Australia, Papua New Guinea and Indonesia, according to Sorenson and Payne (2005). Accordingly, it is not part of the Eudynamys genus (the true koels), with which it has previously been placed. Description The long-tailed cuckoo has a length of approximately 40–42 cm; wingspan of approximately 47–52 cm and weighs about 120 grams. Large cuckoo with broad pointed wings, very long tail and softly rounded at the tip, and short stout with two coloured bill, both slightly hooked tip. Brown barring to brown upperparts, and dark streaking to white underparts. Both males and females share similar features. Young cuckoo is very different from adult: it is spotted, and buff underneath and on sides of head and neck. Adult. Top of head and hindneck, dark brown, boldly streaked buff. Supercilium, White's, bordered below by bold dark-brown eye stripe continuing downsides of neck, cheeks, chin, throat and foreneck, whites with thin brown stripes and fine black streaking on near neck and throat. The remainder of the upperparts are brown with white spotting on wing. Tail is tipped white. The underbody is white with course black brown streaking. Legs and feet are gray to green. Long-tailed cuckoo have a loud and intense sound, a "shrill whistle"; it is sometimes called the "screamer". Distribution and habitat Endemic to New Zealand, where they can be found on Little Barrier Island, the West Coast of the South Island, Nelson, and throughout the central North Island. Long-tailed cuckoo prefer to live in forest on mainland and near shore or offshore islands, from sea level. in mountainous areas, more often on vegetated ridges than in valleys. Usually in dense, closed canopy of native forests dominated by beech Nothofagus, broadleaf species or podocarps or mixtures, with or without shrub layer. Usually surrounded by plantations of Pines (Pinus). Can be around other vegetation such as manuka
