The Cornell Lab of Ornithology has two choices from the campus property:
Great Blue Heron nest within Sapsucker Pond here.
Bald Eagle nest in a cottonwood tree on private property near the Decorah Fish Hatchery (operated by the Iowa Department of Natural Resources), on the banks of the babbling waters of Trout Run in extreme northeast Iowa. Video here.
Another Bald Eagle nest at the National Conservation Training Center in West Virginia can be seen here.
There are plenty more out there. Use the comment section to put a link to your favorite bird cam!
