14. Behavior of bird / circumstances of observation:  3 birds seen together almost throughout.  All flew several hundred yards together from first location to second.  At that location, all landed on barbed wire fence lines or on nearby live oak.  Flycatching behavior noted as expected.  Also, at one point, two younger birds flew up to adult bird and began to beg with open mouths and fluttering wings.  Some calling noted, especially young birds.

15. Description:

 

(Description of one young bird seen best)

Crown, nape, and anterior of mantle gray shading into a greenish gray at about level of shoulders.  .   Uppertail coverts blackish, edged with rust.  Sheathed feather coming in on back.    

White chin and throat with grayish was on the sides of the throat.  Yellow breast and belly with a grayish wash across the yellow of the upper breast.  Undertail coverts paler lemon yellow. 

Tuft of yellowish feathers at the dorsal base of the bill.   Blackish mask with eyeline as upper border, mask darker anteriorly, fades into neck in back.  Black lores. 

Wing coverts blackish and evenly edged with white except for brownish or buff edges near bend of wing; flight feathers and greater and median coverts contrasting with greenish gray of lesser coverts.  Scapulars and tertials edged whitish.   Bend of wing yellow. 

Notched tail, with even graduation of rectrix length from shortest central pair down; notch of tail in relaxed position forming almost a right angle.  Rectrices edged brownish.   Rectrices look juvenal.  

Eyes dark.  Mouth lining appeared red. Legs grayish or blackish. 

 

Adult bird appeared roughly similar, however, with less vivid coloration on mantle due to wear.  Adult bird had notched outer primaries, visible when wings hung relaxed at sides. 

 

16. Voice:  Young birds gave repeated, insistent peeping calls.  At least one bird (the adult?) gave a rapid-fire twitter burst.

17. Similar species (include how they were eliminated by your observation):  No visual differences eliminated Couch’s, although the bill on the adult seemed large.  The trilled call seemed entirely consistent with Tropical call.  While it has been pointed out that Couch’s can trill, the absence of any other Couch’s type calls and the similarity between calls we recorded and the calls of Tropical seem to be the best match.
