I checked out this site on an evening stroll yesterday. It's located 20 minutes north of Queretaro, and some fantastic species have been reported here, such as
Wood Stork (see
http://birdingmexico.blogspot.mx/).
Lots of good muddy areas held Least Sandpipers, a few
Baird's Sandpipers, 1
Lesser Yellowlegs, some
American Avocets, many Killdeer and this sublime
Semipalmated Sandpiper. Didn't check all waders properly, I can see however how this place holds the potential to attract really good birds.
Not many duck left now in Queretaro, most having returned to breed in North America, but I did see a few Northern Shoveler, Ruddy Duck (resident), Mexican Duck (resident) and Blue-winged Teal.
Also, still c.70
American White Pelicans loafing around. Plenty of
Neotropic Cormorants and
White-faced Ibis too, as well as Great Egrets, Snowy Egrets and Cattle Egrets, and the odd late
Black-crowned Night Heron.
Migging Yellow-rumped Warblers abounded on the edges of the lake, and Barn and
Bank Swallows were joined by some Nighthawk at dusk hawking for insects.
All in all, not a bad evening. Certainly a place I will return to.
