Without a doubt, stick with Brazos Bend State Park. It has done better with the drought than any other place I can think of.
Plenty of birds. Get there early in the morning and stay all day if your lucky
and it stays cloudy, or until the sun gets harsh, about 9-10:00 AM, or after about 5:00 Pm.
At least you will be able to take plenty of bird (and alligator if you like) images.
As a matter of fact, I would not waste gas, and time, going anywhere else, if avian photography is your main goal. If you want to just drive around, thats different.
With the drought, and the fact that you don't know the area, any other
place you go to (and I go to them all) has a high likelyhood you will be
disappointed. Again, that is if your main goal is avian photography. Getting to a location doesn't mean you will find birds (with the exception of BBSP). Brazos Bend is as close to sure thing that you will find this time of year. regards~Bill
