Adults of the nominate subspecies have a dark grayish brown forehead, crown, lores, and ear coverts; their cheeks are white. The crown feathers form a slight crest. Both sexes have a partially hidden lemon or canary yellow patch in the center of the crown though females' are narrower. Both sexes have a grayish brown nape that is paler than the rest of the head. Voice: The thick-billed kingbird has a variety of calls that apparently have different functions. The most frequent is a "wo-parted phrase, T t t t t, t T t tt rwheeuh t tt". Others include chatters, a "loud, rasping tch-uhrreeE, a "harsh ruhr", and a "clear tch-rroy".

White-throated Kingbird
Tyrannus albogularis
The white-throated kingbird is 20 to 21 cm (7.9 to 8.3 in) long and weighs 35 to 38 g (1.2 to 1.3 oz). The sexes have the same plumage. Adults have a mostly pale gray head with a partially hidden pale orange or yellowish patch in the center of the crown. They have a dusky band from the lores to the ear coverts that forms a "mask". Their upperparts are mostly bright olive green. Their wings are dull blackish brown with pale edges on the coverts and secondaries. Their tail is black and notched. Voice: The white-throated kingbird is not very vocal. Its typical call is "a shrill, trilled tic tic tic'i'i'i'i'i'i'i'i'i'i'i". It also occasionally makes a "long and irregular series of tic notes and trills" that may continue for several minutes.
