I'm going to tell you what happened while I was out watering tonight, but you may not believe it. I still can't and I was there! While watering my tomato plants I noticed movement on the ground off to my left. Turns out it was a little bird. He was buried in the dirt, head first, belly up, up to his legs! He was struggling, trying to get out, but he was in tight, like someone planted him! Just the tail end sticking out! I started to dig the dirt away with my finger, but was afraid I'd break his neck so I dug my fingers under him and popped him out. Poor thing couldn't hardly fly, just flopped off and sat there panting. He finally flew off, but not very far above the ground. Still can't figure out how he got in that position. Very, very weird, but so happy I happened to be there to help him out.
