Once there were two black snakes in our yard. And we were terrified as heck. We wanted to call Animal Control or something, but my dad decided no and that he wanted to video-tape them. So, he did. Eventually though we got bored and left him. Then two minutes later my family seriously forgets we have two black snakes in our yard. While I was upstairs, I was watching TV when a heard a Bald Eagle or something scream. I ran to my window, and there were the two snakes battling a bald eagle in the backyard. The Bald Eagle grabbed one of the snakes (the male) and flew up to the sky never to be seen again. And then the female went slithering away to chase its husband.
This happened when I was 9 or so. And that's why you should always entrust snake problems to eagles. The End!
