The Saddle Pad and the Bird

So i brought home Sky's saddle pad to wash since it hadn't been washed since last fall! He was sheddind, so it was really hairy. Mom told me to leave it on the porch so we wouldn't get hair all through the house. A few minutes later, we looked out and this little bird was picking off the hair and then flying away. She came back to get mouthfulls three or four times to make her nest!
