Worthen's Sparrow
Tanque de Emergencia,
Coahuila, Mexico
5 October 1990

Ro Wauer and I were on a Mexico trip in Sept. and Oct. 1990. One of the goals of this trip was net some Worthen's Sparrows in a spot we knew they could be found. There are a few shots of a hand-held bird posted here. This is apparently a 1st winter bird, so not fully mature. We saw at least 8 Worthen's Sparrows this day. There will be one other record of this species from 1994. I co-authored a paper in an ornithological journal in 1997 about this bird and its distribution in northern Mexico. That paper is cited below.
