spur of the moment science

Thursday when we went to feed the dog, there was a bird diving and chirping and going crazy, as we looked around we noticed the dog has a little bird in its mouth. So we went outside and she was sitting in our playhouse next to the bird she had not harmed the chick , i made her get away from it , she did not want to go in so we forced her in and then i called the neighbor to help figure out how to get this young bird back to a nest, the mother stayed close the whole time but far enough away we couldn't get her. then after a few minutes the chick hopped through our fence them the mom would swoop down to the baby then fly up to the shed in the other yard where there is no dog. the baby would hop along the fence and the mother would swoop and this happened for some time , but sowed the kids and talked about what was happening. it was sad but a neat thing to see.
