The short-crested flycatcher (Myiarchus ferox) is a species of bird in the tyrant flycatcher family Tyrannidae. It is found in every mainland South American country except Chile. The short-crested flycatcher is about 18 cm (7.1 in) long and weighs 21 to 34 g (0.74 to 1.2 oz). The sexes have the same plumage. Adults of the nominate subspecies M. f. ferox have a smoky brown crown and upperparts; the crown has a slight crest. Their face is otherwise gray. Their wings are mostly dark brown with whitish yellow to grayish outer webs on the tertials. The wing's greater and median coverts have wide paler fuscous brown tips that show as two wing bars. Their tail is dark smoky brown with rufous edges on the feathers that quickly wear away. Their throat and breast are gray that is slightly lighter on the throat. Their belly and undertail coverts are yellow. Subspecies M. f. brunnescens has lighter brown upperparts than the nominate with wider rufous edges on the tail feathers and an olive-green wash on the flanks. M. f. australis is similar to brunnescens but with a less brown crissum. All subspecies have a dark iris, a dark bill, and dark legs and feet. Juveniles have rufous tips on the wing coverts and rufous edges on the tertials and outermost pair of tail feathers.
