Might have to be hand fed with a syringe and formula to survive. Wild birds just won't eat with the stress of human presence, but not able to find food if left alone.
You might find a local aves rehabber and ask advise, and see if a vet can deal with the eye problem. Might cost a bit without help of wildlife federation.
Rescued an injured bat, very reluctant to eat at first, little guy cost near 2 grand, and then could never fly again.
Thanks to angel flight, he was sent to live his life in a Texas sanctuary.
A note,,animal control will only euthanize it, won't rule that out anyway.
Hey, little guy finally took blended meal worms with a syringe, finally started eating them from a tiny bowl.
Blended meal worms, chilled, is a bit like yogurt, you should try it.
