Cattle Tyrant
Machetornis rixosa
The cattle tyrant is a highly terrestrial tyrant flycatcher, 19.5–20 cm (7.7–7.9 in) long and weighing 29–40 g (1.0–1.4 oz). The plumage of the nominate subspecies is mostly olive-brown above and yellow below, with a grey head with a thin dark eyestripe and a paler, whitish throat. The thin bill and legs are black. The two other subspecies differ from the nominate in having the head less grey, more like the olive-brown of the back, and a yellower throat.

Hammond's Flycatcher
Empidonax hammondii
Adults are 12–14 cm long (4.7–5.5 in), span about 22 cm (8.7 in) across the wing and weigh 8–12 g (0.3–04 oz). They have grayish-olive upperparts, darker on the wings and tail, with whitish underparts; they have a conspicuous white eye ring, white wing bars, a small bill and a short tail. The breast is washed with grey and the sides of the belly with yellow. Females usually have a shorter, wider bill than males. Immature birds are similar to adults, but have broader wing bars and are more buff. Many species of Empidonax flycatchers are very similar in appearance. Voice: The song is a multi-versed, hoarse ssilit, greeep, silit, pweet. The call is a sharp peek. Hammond's flycatchers do not sing during the fall migration or on wintering grounds. They start singing in early May, shortly after their arrival on breeding grounds.
