The social flycatcher (Myiozetetes similis) is a passerine bird from the Americas, a member of the large tyrant flycatcher family (Tyrannidae).
It is sometimes split into two species with the social flycatcher, Myiozetetes texensis, from Costa Rica northwards to Mexico and the vermilion-crowned flycatcher, M. similis proper, from southwest Costa Rica across South America.
The head is dark grey with a strong white eyestripe and a usually concealed orange to vermilion crown stripe. The upperparts are olive-brown, and the wings and tail are brown with only faint rufous fringes. The underparts are yellow and the throat is white. Young birds have a paler eye mask, reduced crown stripe, and have chestnut fringes to the wing and tail feathers. The call is a sharp peeurrr and the dawn song is a chips-k’-cheery.
