Pigeon loft

Found another bird in the garden yesterday; not sure what it is, I couldn't see any distinctive markings (it was so wet). Maybe I'll be able to tell when it's dried a bit. A friend tells me she has 5 dead pigeons in her loft that I can have too. She discovered them when her ceiling came down! She doesn't know what state they're in though - she's reluctant to get too close...
