Hi Paula,
Yes, absolutely. The best way to tell if he is the same bird is for him to be returned to familiar surroundings and people. He would likely calm down after a few days and interact with his owner. In some cases, they instantly recognize their owner and show their previous personality. I know often when someone finds a bird, they want to keep it if the owner isn’t located. Hopefully they will bring the bird to this lady’s home and agree to let her keep him temporarily to see if it is her bird, and of course he would remain with her if he is.
Thank you for asking Lafeber,
Brenda
