Warbler rescued from screened in porch

After finding this bird trying to escape from a screened in porch. I was able to put a towel between it and the screen. I then took him outside. I uncovered the towel, do he can see his surroundings. He rest for a while to get his bearings. As Tux, the cat, 🐈‍⬛ approaches the yellow warbler flys away.
