MEGA - Anhinga at Presa de la Constitucion

First visit to Presa de la Constitucion near San Gil for a few months, and it was well worth it to find an ANHINGA. These Cormorant-like birds are fairly common in coastal areas of Mexico, but aren't generally found inland.  Definitely represents a very rare bird for the state of Queretaro, particularly the lower half of the state.

Extremely high water levels here meant that the only waders I found were a few Spotted Sandpipers and a Killdeer.  At this time last year, the shoreline was at least half a mile further in.

A few Neotropic Cormorants allowed for an interesting comparison with the Anhinga.  Both species were sharing the tree tops with a reasonable amount of Great Blue Herons, Great Egrets and a few Crested Caracaras.  On the water, small flocks of Mexican Ducks and Northern Pintails, and some Ring-billed Gulls.

The bushes and trees around the lake were full of critters.  Plenty of Yellow-rumped Warblers and at least 10 Common Yellowthroats.  Some pishing in the woods by Fiesta Americana brought in 2 Orange-crowned Warblers,  1 Wilson's Warbler, 1 Cassin's Vireo, 8 Blue-grey Gnatcatchers and at least 5 Ruby-crowned Kinglets.

Other birds - Bewick's Wren, Marsh Wren (2), Abeille's Oriole  (20+), Hooded Oriole, Curve-billed Thrasher, Blue Grosbeak.

It's a big old lake at the moment.  I'm sure a full walk around the perimeter  would yield a huge day list, and potential rarities.
