Death of a baby bird

Today I went into my backyard and noticed that the little baby bird on the ground was dead. I was so sad. Last Sunday I heard a bluejay singing and shrieking in the back yard. My dog was sniffing at something in the grass. As he did that a large momma bird shrieked and swooped down at him as if she were going to attack. I looked at where the dog was and saw a baby bird with newly formed feathers sitting quietly. It was still alive at the time. I told Trout (the dog) to leave the baby bird alone and come into the house with me, which he did. I felt helpless, knowing that there was no way I could take that bird and save it. I thought about retrieving it and putting it in a handmade nest, but I then figured it wouldn't eat from me and its mother certainly wouldn't take care of it once I handled it. So I let it be, hoping naively that perhaps the momma bird would somehow retrieve it and put it back into its' nest. But that wasn't to be. So now my husband is going out there to bury it in the garden. The momma bird is no longer in my tree; no more singing and shrieking. She's gone too.
