Is this sparrow undamaging?
I live in the northeast.. and right now temps are very low.. in that is a small sparrow living behind an old metal doorbell type of thing right external of my front door. it has been there for a few days, and is within almost all of the time, very from time to time do we check for it, and it's not there.. but my questions are... are sparrows built for the cold weather? do they normally live alone? is this a typical type of "nest" for one? and is in attendance anything I can do, if this is an unsafe situation for it? thanks in credit for any help.
Sparrows do not migrate and can live in particularly cold temps. I have tons in my bushes in the spring, summer and winter. It have found a place it likes. I would watch it and make certain it can fly. If not it will die. If it cannot fly need to bring it in. Can catch it near a butterfly net. Put in a small cage or box near a heating pad underneath outside bottom of it and cover partly way with a towel or blanket. Put some seed and hose in the cage or box. Put in a dim lit room. Stress can murder these little guys fast. Then get on the phone and call a vet that see injured wildlife or who can refer you to a wildlife rehabber in area. This is free for wildlife(vet and rehabber). If vet cannot refer then ring the DEC they can. It may have made this it's roosting spot, safe spot, or nesting spot. Usually where you find one though you find lots. Not often that one is alone. May have been kicked out of flock due to infection or injury. Keep eye on it and go from there. Could put birdhouse out to see what it does. Also put some food out there and scrutinize and see what happens. Good luck and thanks for caring for the little critter.
