My Lab, Chance, was hopping around and all excited, so I went out to see what was going on.  He had somehow caught a little sparrow, and was playing with it.  I took it from him, and it was alive.  No blood; no open wounds.  Wings were intact.  It was looking at me.  But it was only moving its head a bit, and she twitched her leg when I touched it.  I wrapped her in a small towel, and nestled her in my bathroom sink.  I did get her to drink a bit of water.  So, I'm thinking she might make it.  I checked her about 15 minutes later, and she was lying quietly, her eyes open.  I was really hoping that with a bit of rest, she would be O:K:  Sadly, not to be.  She was dead the next time I checked on her.  I can only imagine her terror, as this large "beast" had her in its mouth.  His fun was her death...so sad.
