The kingbird (Tyrannus melancholicus) is a large tyrant flycatcher. This bird breeds from southern Arizona and the lower Rio Grande Valley of Texas in the United States through Central America, South America as far as south as central Argentina and western Peru, and on Trinidad and Tobago. Birds from the northernmost and southern breeding areas migrate to warmer parts of the range after breeding.
Description and ecology[change | change source]
An adult tropical kingbird is 22 cm (8.7 in) long and weighs 39 g (1.4 oz). The head is pale gray, with a darker eye mask (area around its eyes), an orange crown stripe, and a heavy gray bill. The back is grayish-green, and the wing and forked tail are brown. The throat is pale gray, becoming olive-colored on the breast, with the rest of the underparts being yellow. Both male and female are similar, but young birds have pale buff edges on the wing coverts.
The call is a high-pitched twittering trill, tree-e-e-e-e-e-e, with a more complex version sung by the male at dawn.
Their breeding habitat is semi-open areas with trees and shrubs, including gardens and roadsides. Tropical kingbirds like to view their surroundings from an open perch, usually high in a tree. They take long flights to catch insects in mid-air, which is called hawking. They sometimes hover to pick food off of plants, which is called gleaning. They also eat some fruit.
They make a flimsy cup nest in a tree. The eggs are cream-colored with reddish-brown marks. The female incubates the typical clutch of two or three eggs for 16 days. After they hatch, it is about 18–19 more days until fledging.
