Lost Homing Pigeon
About six weeks ago, a white homing pigeon (I think it's a homer) showed up in my yard. I caught it in a large trap that I use for big critters, so I could read its orange band. Well, its band has nothing on it. So, I released the bird, however, it seems to enjoy our hospitality, and it shows up in our yard every day for chow and shelters itself underneath our trees. He's out there right now, taking a snooze. I thought he/she would have moved on by now, but it hasn't. I assume that it's a young bird because it has grown since it first arrived, and it's starting to look mighty tasty. No, I won't eat him--it's rude to eat guests.
Anyway, the bird seems quite content to live in our yard, but it really doesn't have any real sort of shelter, and I'm not in the mood to build him a "house." I'm concerned that it will eventually fall prey to a local cat, or one of the hawks that frequent the area.
Any suggestions? Do I just let him be, or does anyone want to come pick this guy up? I live in SE Michigan, in Western Wayne County.
