All birds have feathers, wings, two legs and they lay eggs: '¢ A pair of eagles builds a huge nest of sticks that they add to every year. They make the largest nest of any Canadian bird. '¢ An owl can't move its eyes, so it has to turn its head. An owl can turn its head almost all the way around to the back. '¢ The ruby-throated hummingbird beats its wings 55 to 75 times per second. Its tiny heart beats up to 1200 times per minute. '¢ A blue jay's feathers aren't really blue. The feathers reflect light, making the bird look blue.
