Look in the phonebook for wildlife pickup/vets/ and even the city website.
I just left a messages at 2 numbers that WildBirds Unlimited gave me. I will just put the bird in a cat kennel tonight in the greenhouse if no-one gets back to me today.
At least that way, it can’t get hung up in the heater tonight. I have a whole flock of mourning doves that come to my feeders. They mate for life...so it is kinda sad wondering which other bird is it’s mate.
