These Mountain PloversCharadrius montanus were photographed
at the Sod Farm by H140 and H57, 11 miles nw of Pearsall, Frio
County, Texas on March 03, 2005. They were following the turf-pulling
tractor, and allowing very close approach (I was given permission
to enter and photograph them this one time.) I gather that aging/sexing this species is very difficult; I'd be very interested in any
feedback discussing my guesses at the age/sex/plumage of the individual birds
