On the third Sunday of every month, Sociedad Audubon de México A.C. conducts a bird walk for both its members and the public to enjoy.
We visit nearby waterways along the Río Laja, the Allende Dam and the Botanical Gardens. When weather and water levels permit, we also visit Audubon's proposed Bird Refuge, just above the Dam.
On recent bird walks, we have seen a variety of both water and land birds including: Caracaras, Cowbirds, Common Grackles, Meadowlarks, Larksparrows, Kestrels, Loggerhead Shrikes, Vermillion Flycatchers, Killdeer, Brown Towhees, Cassin's Kingbirds, Egrets, White-Faced Ibises, Canvasback Ducks, Northern Shovelers, Ring-Billed Gulls, White-Tailed Kites, Black-Backed Orioles, Cactus Wren, Chipping Sparrows, Curve-Billed Thrashers, various types of woodpeckers, Hummingbirds, Inca Doves, Kiskadees, Lesser Gold Finches, Mourning Doves, Red-Tailed Hawks, White Winged Doves and one Yellow-Rumped Warbler.
Participants in the winter bird walks at the city's botanical gardens, El Charco del Ingenio, have witnessed another fascinating phenomenon: the emergence of hundreds, perhaps thousands, of white-throated swifts from narrow cracks in the wall of the canyon. This usually takes place sometime after ten in the morning when, apparently, the rock face gets warm enough to trigger their exodus. One can hear the birds cheeping within their caves, and then wave after wave of them flies out, until no more cheeping is audible. The reverse, the swifts returning to their rock face, takes place a little before sunset.
Our group meets in front of the Instituto Allende, Ancha de San Antonio #20, at 8:00 a. m. and leaves by 8:15 a. m. Transportation is always available. We advise that participants bring water, a hat, sunscreen and binoculars, if they have them. A car usually returns to town by noon.
