The squirrel cuckoo (Piaya cayana ) is a large and active species of cuckoo found in wooded habitats from northwestern Mexico to northern Argentina and Uruguay, and on Trinidad. Some authorities have split off the western Mexican form as the Mexican squirrel-cuckoo (Piaya mexicana ).

S
starts withThis large and extremely long-tailed cuckoo is 40.5–50 cm (15.9–19.7 in) long and weighs 95–120 g (3.4–4.2 oz). The adult has mainly chestnut upperparts and head, becoming paler on the throat. The lower breast is grey and the belly is blackish. The central tail feathers are rufous, but the outer are black with white tips. The bill is yellow and the iris is red. Immature birds have a grey bill and eyering, brown iris, and less white in the tail. It resembles the little cuckoo, but that species is smaller and has a darker throat.
There are a number of subspecies with minor plumage variations. For example, P. c. mehleri, one of the South American subspecies, has mainly brown (not black) outer tail feathers. Additionally, the subspecies from Mexico, Central America, and northern and western South America have a yellow eye-ring, but this is red in the remaining part of South America.
It makes explosive kip! and kip! weeuu calls, and the song is a whistled wheep wheep wheep wheep.
The squirrel cuckoo is found in woodland canopy and edges, second growth, hedges and semi-open habitats from sea level to as high as 2,500 m (8,200 ft), although it is uncommon above 1,200 m (3,900 ft).
This species’ English name derives from its habit of running along branches and leaping from branch to branch like a squirrel. It normally flies only short distances, mainly gliding with an occasional flap.
It feeds on large insects such as cicadas, wasps and caterpillars (including those with stinging hairs or spines), and occasionally spiders and small lizards, rarely taking fruit. Its non-flying prey is typically taken off the foliage with a quick lunge, but wasps may be caught on the wing. Squirrel cuckoos are often observed to forage peacefully alongside small mammals such as common marmosets (Callithrix jacchus ) during the dry season for cocoa beans. In particular, they can be seen to attend army ant columns together, picking off prey flushed by the ants, and occasionally will join mixed-species feeding flocks.
The nest is a cup of leaves on a twig foundation, hidden in dense vegetation 1–12 m (3.3–39.4 ft) high in a tree. The female lays two white eggs.
The squirrel cuckoo is plentiful in most of its range and appears to be quite tolerant of human disturbance, as long as wooded land remains. Compared to many cuckoos in the world, it is relatively bold and conspicuous, although it most often encountered skulking about within vegetation. Owing to its wide range, it is considered a species of Least Concern by the IUCN.
