Habitat: 

hardwood bottomland surrounded by open sedge fields and scrub lines

Behavior of bird: 

bird first seen flying in from the east, over the Henderson levee.  it then landed in an A. rubrum treetop, and was behaving excitedly; constantly looking around in sharp head movements and looking about its surroundings.  the bird made a few brief flights of no more than 2-3 meters at a time, sticking to the top 1/3 of the trees it visited.  at no point did the bird make an attempt to forage. it kept moving further down the treeline north until we lost sight of it. in changing positions in the trees, it both faced us and away from us.

Description:

larger Myiarchus flycatcher with bright lemon yellow belly, ending at mid-chest area, extending onto flanks and undertail coverts.  reddish noted in primaries, as well as retrices, the outer tail feathers appearing darker than the inner. undertail pattern was not well seen. bill was dark, heavy and long.  upper chest and throat was a light gray color, becoming darker behind the eye, where it became a brownish-gray on the crown. this color remained uniform from the forehead all the way down the back.

Voice:

n/a

Similar species:

1) Ash-throated was initially suspected, but the yellow underparts were too strong of a yellow, along with the longer and heavier looking bill.  the back of the bird also appeared to be darker than most Ash-throats I've seen.

2) Great Crested was eliminated first based on probability, then the throat and chest simply did not seem to be as dark a gray as Great cresteds usually have.

3) Dusky-capped, Nutting's & La Sagra's were not seriously considered in the first place, but this bird had a much heavier and longer bill, plus overall size was just too large.
