It looks very oozing from head. Looks like you need to get some stitches in that head and clean wound. Wipe wound if you haven't already. Anybody near you-bird rehabbed? I've dealt with serious bird issues this week also. It's awful because I'm telling you, these babes are so sharp and smart.Update: Seems to have spasms every once in awhile and breathing is getting heavy. Less hopeful. Still alert in between spasms though.
Also reading that I probably should not have given a pigeon with head trauma heat. If someone could elaborate I would appreciate it.
