From Jason Bonilla with the Houston Audubon Society:

We had our July bird survey this morning. The birds must have been as hot as we were as we only came away with 14 species today. One of the species was a Great Crested Flycatcher! We saw 8 Red-vented Bulbuls too. The full list is below (data for all years in the attached spreadsheet).

Since the birds were staying cool, we had some time to talk about doves, and how to identify doves by counting the number of "coos" that each species makes. My 10yr-old son Noah helped to demonstrate this for the group (he's pretty good at it). So here is a trick that I listen for:

Mourning Dove = 5 coos: oo(1)woo(2), woo(3), woo(4), woo(5). Also, their tail feathers will whistle when they take off.

White-winged Dove = 4 coos: who(1)-cooks(2)-for(3)-you(4) (like a barred owl barking out "who cooks for you" (and leaving out the following "who cooks for you all").

Eurasian Collared Dove (Noah's specialty): 3 coos: woo(1)-WOO(2)-woo(3). They also scream on they're way down as if coming in for a crashing landing.

Inca Dove = 2 coos: no(1) hope(2).

Common Ground Dove = 1 coo: an ascending wah-up(1).
