Flycatchers are generally colored in hues of olive green, gray, white, black, brown, and yellow. Most have erectile crests, stiff bristles around the mouth, and a bill that is usually hooked slightly at the tip. The great kiskadee, however, can not be mistaken for any other Texas species. This large, colorful flycatcher is brown above and bright yellow below. It has reddish brown wings and tail and a boldly striped black-and-white head. A yellow crown-patch is often concealed.
