I don't know much about Texas and it's birds. Why don't you place a question on the Texas forum "How to attract beneficial birds" you should get some answers. There are quite a few good gardeners and bird lovers there. Salvias forum also has Hummingbird lovers. Give them a try to.
These big birds like blackbirds, crows, eagles, etc. need a clear flight path to land and take off. Place a few strategic small trees and spoil their fun. Other birds hover, so they do not need a clear flight path.
Here I have put down fruit trees, small ones that birds love to eat. Berries, etc. which do not have much value to humans except maybe kids. The fruit attracts the birds and the trees provide nesting. You can find out what your area birds love, then grow them but for that Texas Forum would be best.
