I will start with the kiskadees and similar colored birds. The Great Kiskadee (Pitangus sulphuratus) is a stunning 8.5" bird, with brown and rufous wings, bright yellow underparts and striped head. This bird does occur in the USA in south Texas. On reviewing our photos, I guess we didn't take any as we had some from Texas, so here is the bird.
The 4th similar bird is the Social Flycatcher (Myiozetetes similis). It is the size of the Lesser Kiskadee, but the crown and sides of face are dark brownish gray rather than black and the back is more olive.
The much smaller (5.5") but similar Piratic Flycatcher (Legatus leucophaius) lacks the streaking on the back and rufous tail. It has a much smaller bill as well.
The Paltry Tyrannulet (Zimmerius vilissimus) is a tiny (4") flycatcher best IDed by voice. But it does have yellow wing edges and gray underparts that differ from other tiny flycatchers.
The Long-tailed Tyrant (Colonia colonus) is small (4.5") flycatcher with 2 elongated tail feathers (longer in males). It is black with a white stripe across the face and another down the back.
The Tropical Kingbird (Tyrannus melancholicus) is gray with yellow underparts. It lacks the white tail edges of the Western Kingbird which is the only other bird of this coloration in Panama. Also, the notched tail is diagnostic. This bird occurs along the southern border of USA.
Happy birding and photography,
