Slaty-headed Tody-Flycatcher

The slaty-headed tody-flycatcher is about 9 to 10 cm (3.5 to 3.9 in) long and weighs 6.7 to 8.5 g (0.24 to 0.30 oz). The sexes have the same plumage. Adults of the nominate subspecies P. s. sylvia have a gray crown and nape. Their lores are gray; they have a white line above the lores and a broken white eye-ring on an otherwise gray face. Their back, rump, and uppertail coverts are olive. Their wings are blackish with narrow yellowish edges on the inner flight feathers and large yellow tips on the coverts; the latter show as two wing bars. Their tail is olive. Voice: According to Hilty, the slaty-headed tody-flycatcher's vocalizations are "insect- or froglike". They include "a soft, gravelly trup or trup grrrr, varying to tik trrrrrrr; nasal froglike grrrrrrr also given singly. When excited tíc-a-turrr". Fagan similarly describes one call as "a 2-part tip!-purrrrrrrr".
