White-cheeked Antbird

The white-cheeked antbird is 13.5 to 15 cm (5.3 to 5.9 in) long and averages about 24 g (0.85 oz). Adult males of the nominate subspecies G. l. leucaspis have a chestnut-brown crown and nape. They have bare blue skin around the eye and a blackish band from the lores through the eye that continues down the side of the neck and along the flanks. Their back, rump, wings, and tail are chestnut-brown with some rufous edging to the wing and tail feathers. Their cheeks, throat, and breast are white and their lower belly dark brown. Voice: The white-cheeked antbird's primary song is a series that "begins with upslurred whistles at even pitch that shorten into rather abrupt notes dropping in frequency and intensity, then lengthen and increase again in intensity, finally decreasing in intensity and becoming harsh".
