The Social Flycatcher or Vermilion-crowned Flycatcher (Myiozetetes similis) is a passerine bird from the Americas. It is 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.
In appearance, the Social Flycatcher resembles a smaller Boat-billed Flycatcher or Great Kiskadee. The adult is 6.3–7.1 inches long and weighs 24–27 grams. 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. [Wikipedia]
