This image has been examined by several assilid experts at several universities and the consensus of opinions is that an ID beyond the genus level is not possible without examination of a specimen. They agree on the genus ID, however.

Collared Plover
Uvalde National Fish Hatchery
Uvalde, Texas
11 May 1992

This was the first (and remains the only) North American record of this species. The Collared Plover is a species of central and South America. I have seen it in Mexico as far north as the coast of Tamaulipas, 200 miles south of Texas. On 9 May 1992 a Collared Plover was discovered by two independent parties at the Uvalde Fish Hatchery, Uvalde, Texas. I was able to see and get a few photos of the bird on 11 May. It was last seen 12 May. If you look under the "accidentals" section of either the 5th or 6th edition of the National Geographic Field Guide to the Birds of North America, you will see an account of this record. The Texas Bird Records Committee has one of my shots on its web page of this species at:
