We found lots of interesting books at the library, but the internet was also helpful. We went to each other's houses lots of times to research together. One of our dads helped us because he could lend us good books. Both of us found good resources at the library and at our houses. We found that some internet sites didn't have what we expected, but some had good information for us.
Birds of prey have good eyesight.
They need it so they can see their prey from distances. For instance, an eagle's eyesight is 8 times better than a human's eyesight. Birds of prey have their eyes on the front of their head so they can see depth, so they can see how far away animals are. Their prey, such as squirrels and mice, have their eyes on the side of their head so they can watch for predators, because they don't need to see how far away things are. Owl's eyes have feathers around them that are arranged in a way to help them see at night.
