The Gray Kingbird breeds from the extreme southeast of the USA through Central America, from Cuba to Puerto Rico as well as eastward towards all across the Lesser West Indies, south to Venezuela, Trinidad, Tobago the Guiana and Colombia. It is found in tall trees and shrubs, including the edges of savanna and marshes. It makes a flimsy cup nest in a tree. The female incubates the typical clutch of two cream eggs, which are marked with reddish-brown.
The adult Gray Kingbird is 25 cm long and weighs 50 gm. The upperparts are grey, with brownish wings and tail, and the underparts are white with a grey tinge to the chest. The head has a concealed yellow crown stripe, and a dusky mask through the eyes. The dark bill is heavier than that of the related, slightly smaller, Tropical Kingbird. The sexes are similar, but young birds have rufous edges on the wing coverts, rump and tail. Gray Kingbirds wait on an exposed perch high in a tree, occasionally sallying out to feed on insects, their staple diet.
