Ash-throated Flycatcher
Myiarchus cinerascens
The ash-throated flycatcher is a medium-sized tyrant flycatcher, measuring 7.5 to 8.6 in (19 to 22 cm) in length with a wingspan of 11.8 to 12.6 in (30 to 32 cm) and a mass of 0.7 to 1.3 oz (20 to 37 g). Overall, it is slim and long-tailed, with a slightly peaked crest on its relatively large head. The upperparts are olive brown, with a darker head and short crest. The breast is gray and the belly is a very pale yellow. The brown tail feathers and wings have rufous outer webs, and there are two dull wing bars. The sexes are similar. Voice: The ash-throated flycatcher is separated from other confusingly similar Myiarchus species by its calls, a burry kabrick and a rough prrt or wheer heard year-round.
