The black-throated trupial ( Icterus gularis ) is a species of songbird from the starch family (Icteridae) that occurs in North and Central America .
description
Appearance
The black throated troupial reaches a total length of 25 centimeters and is thus the largest of all American troupials. It weighs up to 56 grams. Head, flanks, rump and belly are colored bright orange to yellow orange. The wings are mostly black, but interspersed with some white feathers. The area around the eyes and the throat are black and thus eponymous. The tail is also black. The sexes are very similar in terms of drawing. The beak is strong and horn-colored black and gray. The iris is black. Legs and feet are slate gray.
Vocalizations
The singing of the black throated troupial is described as a loud, musical, often hesitant string of whistling tones. Single, harsh, scratchy tones are used as an alarm call.
distribution and habitat
The distribution area of the black throated troupial stretches from the southern tip of Texas across eastern Mexico to Guatemala , Honduras , Belize and Nicaragua . He prefers to live in open forest landscapes.
Way of life
The birds live in pairs and are monogamous . They feed primarily on various types of insects, and occasionally berries and nuts .
The nest is woven at the top of twigs in the form of a hanging bag made of elastic thin twigs. It can grow up to 65 inches long and is built by the female alone over a period of three weeks. The average nest height above the ground is about nine meters. Usually around five eggs are laid from March onwards. A second brood sometimes occurs in the southern distribution areas. The breeding season is around 14 days. Both parents feed the nestlings.
Danger
The black throat troup is not uncommon in its areas of distribution and is therefore classified by the IUCN as a 
“ least concern ”. It is protected by the United States Fish and Wildlife Service under the Migratory Bird Treaty Act .
