Details: Having arrived at the ditch at the PAP pecan grove, where Mark Stevensen had just been viewing the bird, I played a couple of call notes of a Groove-billed Ani and had the bird fly up into a mesquite tree in plain view. A dull colored bird, being principally blackish, with a disheveled appearance, being real shaggy around the breast. It had dark gray bare facial skin and dark eye. The bird had a very strongly arched culmen, with groves evident at the base of the upper mandible. The upperparts were fairly uniformly patterned. The wings were glossy with some purplish and greenish highlights. The wings were held drooped below the plain of the body. The tertials appear very long and very rounded at the tips. The tail was a shiny grayish colored slightly darker toward the tip. The tail length about equal to that of the body, and was somewhat graduated with the outermost rectrices being about an inch and a half shorter than the inner rectrices. The centralmost pair of rectrices appeared to be perhaps of a newer feather generation, and were shorter than rectrices #2, by about half an inch. The tail would be pumped up slowly, then dropped again. This was repeated habitually. In flight, the bird flaps its wings several times quickly in succession and then holds itself in a glide with the wings held open horizontal to the body, and the tail spread. The ani moved around on the ground a bit, and would pump its tail up and then swish it sideways back down. At one point the ani was sunning itself, at which time it raised all of the feathering on the neck and upperbreast perpendicular to the body, and wings drooped and tail partially spread. The bird began to vocalize at one point, giving the "tick-quew" call typical of this species, and very different from that of other black birds. I was able to make some voice recordings, which appear in Figure 1.
