Golden-faced Tyrannulet

The golden-faced tyrannulet is 10.5 to 11.5 cm (4.1 to 4.5 in) long and weighs 7.7 to 10.6 g (0.27 to 0.37 oz). The sexes have the same plumage. Adults have a bright yellow forehead, supercilium and area around the eye and a dark stripe through the eye on an otherwise yellowish white face. Their crown, back, and rump are bright olive. Their wings are dusky with bright yellow edges on the coverts and flight feathers. Their tail is dusky. Their throat is yellowish white and their breast, flanks, and belly dull whitish. Voice: The golden-faced tyrannulet is highly vocal. Its dawn song is a "plaintive chu-de-de'e'e". Another author describes it as "a slightly rising, accelerating, laughing series of notes: tee-heeheeheehee". Its daytime calls include "a simple clear 'cleeuw' or 'peeur' " and a "ringing 'teer-tif' ".
