Flycatcher ID

Some pictures from Loreto, Bolivia, 07. November 2009.
The first bird is a Boat-billed Flycatcher. The strong bill easily identifies the species. The next bird is a Great Kiskadee, often identified by it voice when it is repeating the second part of its name. The Great Kiskadee has a large bill, but far from the size of the Boat-billed Flycatcher.

This short billed bird is not as easy to identify as the two first. It is a Rusty-margined or Social Flycatcher. There is much overlap among this two species. My guess is that this is a Rusty-margined Flycatcher mainly because of the coloration on the wing, the black crown and plain wing coverts. It also looks like the Rusty-margined Flycatcher has a darker eye than Social Flycatcher on many illustrations (Birds of Peru, Songbirds of South-America), but this is not mentioned in the text.
