Great Kiskadee

The adult great kiskadee is one of the largest of the tyrant flycatchers. It is 25 to 28 cm (9.8 to 11.0 in) in length and weighs 53 to 71.5 g (1.87 to 2.52 oz). The head is black with a strong white supercilium and a concealed yellow crown stripe. The upperparts are brown, and the wings and tail are brown with usually strong rufous fringes. The bill is short, thick, and black in color. The similar boat-billed flycatcher (Megarynchus pitangua) has a more massive black bill, an olive-brown back, and very little rufous in the tail and wings. A few other tyrant flycatchers – the social flycatcher (Myiozetetes similis), for example – share a similar color pattern, but these species are markedly smaller. The call is an exuberant BEE-tee-WEE, and the bird has an onomatopoeic name in different languages and countries: In Brazil its popular name is bem-te-vi ("I saw you well") and in Spanish-speaking countries it is often bien-te-veo ("I see you well") and sometimes shortened to benteveo. In Venezuela it is called "cristofué" or "Christ did it".

The great kiskadee occupies a wide range of habitats, from open grassland with scattered trees to urban areas. Its range extends from the Lower Rio Grande Valley in southern Texas south through Central America to southern Argentina. It does not regularly occur in Chile. The great kiskadee was introduced to Bermuda in 1957. Two hundred birds were imported from Trinidad in an attempt to control the number of lizards, especially the tree lizard (Anolis grahami) which had itself been introduced. The birds bred successfully and by 1976 the population on the island had expanded to around 60,000. The great kiskadee is omnivorous and has failed to control the number of lizards.

The great kiskadee is a common, noisy, and conspicuous bird. It is omnivorous and hunts like a shrike or flycatcher, waiting on an open perch high in a tree to sally out and catch insects in flight or to pounce upon rodents and similar small vertebrates (such as other birds' chicks and bats). It will also take prey (such as small snakes, lizards, frogs, perched insects, spiders, millipedes and land snails) and some seeds and fruit from vegetation by gleaning and jumping for it or ripping it off in mid-hover, and occasionally dives for freshwater snails, fish or tadpoles in shallow water, making it one of the few fishing passerines. It also visits feeding stations to eat bread, dog food, bananas and peanut butter/seed mixture. Kiskadees like to hunt on their own or in pairs, and though they might be expected to make good use of prey flushed by but too large for the smaller birds of the understory, they do not seem to join mixed-species feeding flocks very often. When they do, they hunt in the familiar manner. Such opportunistic feeding behavior makes it one of the most common birds in urban areas around Latin America; its flashy belly and its shrill call make it one of the most conspicuous.

Breeding. Great kiskadees are monogamous and defend a territory. Both sexes build a large domed nest that has a side entrance. …
