Injured bird, what do?

I live in Galveston county and was on a walk with my dog earlier when I found this grounded bird near a tree, it looks like it may have flown into the tree and injured its wing. It’s very much still awake and alert and even tries to fly every now and then but can barely get off the ground. What should I do and who do I call? Also, can anyone identify what type of bird this is?
