I have a gray and white pigeon with 2 blue bands on it's legs. It is sitting on my wall outside of the house. It doesn't appear to be injured in any way. My neighbor told meit has been there for 2 days and keeps flying into our windows, which are reflective so I assume it thinks it's another bird. I'm not sure what to do, it doesn't fly away when I go out but I tried to approach it and it flew onto the roof. Should I leave it alone? We've had heavy rains for a couple of days but again, it appears to be well.
