Birding and Surveying

I was out counting Grackles and Cowbirds this morning. After stumbling upon some great sites, though, a simple survey turned into a huge birding session.

Great-tailed Grackles and Bronzed Cowbirds fly from their plaza roost to their feeding grounds shortly after dawn. Red-winged Blackbirds, Brewer's Blackbirds, Yellow-headed Blackbirds and Brown-headed Cowbirds, all from the same family, can also be seen forming mixed flocks and feasting in the fields.

Less conspicuous, but present in similarly large numbers are a collection of winter sparrows. Clay-coloured in the biggest numbers, followed by Lark Sparrows, Vesper, Lincoln, Savannah and Chipping.

The abundance of passerines and other food sources in the agricultural land west and north of Tequis. results in fantastic opportunities for birds of prey. This morning I had 12 American Kestrels, 1 Peregrine, 2 Red-tailed Hawks and 3 Black-shouldered Kites, not to mention a ridiculous number of these boys..



Crested Caracaras

In one recently ploughed field I had no less than 10 Caracaras. These resourceful birds will eat anything - insects, reptiles, small birds, fish. Later on in the morning, I had one feasting on a dead cow.
