, Most birds don’t fly very high – usually under 3,000 feet – as they go about their business of looking for food and building nests. But some birds fly very high while they’re traveling to or from their winter homes. Geese are the highest-flying birds of all. Those in the Himalayas Mountains in Asia fly at heights of over 29,000 feet above the earth! Almost all birds have keen vision, and birds of prey have the keenest vision of all. These birds cruise through the air looking for worms, small animals, or other birds on the ground, and must be able to see tiny creatures far below them. Of all birds of prey, the eagle probably has the best vision, with the ability to see a rabbit from two miles away. One eagle was even seen diving for a fish it spotted underwater from three miles away! Even though the eagle’s eyes are on the side of its head, it can see straight ahead!
