Description wikipedia

The buff-breasted flycatcher (Empidonax fulvifrons) is a small passerine bird in the family Tyrannidae, the tyrant flycatchers. It is found from the southwestern U.S.A. to Honduras. The buff-breasted flycatcher is about 13 cm (5.1 in) long and weighs 6.9 to 9.3 g (0.24 to 0.33 oz). It is the smallest member of genus Empidonax in the US and among the smallest overall. The sexes are alike. Subspecies E. f. pygmaeus is the best known. Adults have dull buffy white lores and a faint dull buffy white eye-ring on an otherwise buffy greenish brown face. Their crown, nape, and upperparts are a darker buffy greenish brown than the face. Their tail is grayish brown with paler grayish white outer webs on the feathers. Their wings are deep grayish brown with pale grayish buff edges in the inner webs of the remiges. The wing coverts are deep grayish brown with pale grayish, buffy gray, or dull whitish tips that show as two wing bars. Their chin and throat are light yellowish buff, their breast tawny buff, and the rest of their underparts light yellowish buff or buff-yellow. The colors fade with wear. All subspecies have a deep chestnut-brown iris, a black maxilla, a yellow-orange mandible, and black legs and feet.
