We found a "birdy."

"But it was splattered all over the sidewalk, Mom! There was like, um, well, a POUND of blood that he lost."
"Because you know a baby bird has a pound of blood," says the fourth grader friend.
"Well, we're making it a sign, you know, where we buried the bird. And then you'll know where the baby bird is buried. You should come see it, Mom. Really. But it's already buried so you can only see the spot where the dirt is."
"Ok, I'd love to come and see it."
And this is what I saw when all was said and done...
