I'll have to agree with Slick. Once my friends and I were walking to school and there was a bird who couldn't fly. Its wing was broken, I think. It was sticking out and even if people walked near him, he wouldn't fly away. I wanted to help so bad but I didn't know how to. I was going to school, I couldn't just pick it up and go. Also, some birds may carry diseases and lastly, I wouldn't have known what to do. *shrugs* If I did see an injured dog or cat or something and I was at home, I would probably do my best but something like a crow or a seagull...I just don't know what they could carry with them.
