In the house, the bird got to feeling more secure, so it got away from me before I could release it, but I could see that one wing was injured and it could not fly.
I eventually cornered it in the bathroom and released it in the front yard.
I know that its chances of surviving out there with an injured wing are not wonderful, but it has a better chance out there than in the house. It does seem to be healthy otherwise, and the problem may mend itself, given a little time. There is plenty of food on the ground for a small bird to eat out there, so it is just a question of avoiding predators.
As for Bow, he is quite blasé about the whole thing. Napping again.
