Our 2015 nesting eason story thus far: The female Bald Eagle has laid two eggs this season, on 2/16-17/15 and 2/20/15. Incubation takes approx. 5 weeks. You can view the nest on streaming video here.
One of the longest-lasting Bald Eagle nests in United States history may have been a nest first reported by the Lewis and Clark expedition in Montana in the early 1800s. Here's how Meriwether Lewis described the nest: Below this fall at a little distance a beautiful little Island well timbered is situated about the middle of the river, in this Island on a Cottonwood tree an Eagle has placed her nest; a more inaccessible spot I believe she could not have found; for neither man nor beast dare pass those gulfs which separate her little domain from the shores. Pictured just above the photo's center is the island on the Missouri River where Lewis and Clark discovered a Bald Eagle nest in 1805. Photographed by J.C. Cowles, 1880s.

Raynolds, of the Corps of Topographical Engineers, reported that there was still an eagle's nest in a cottonwood tree on the island. Reynolds even saw "this peculiarly American bird" perched nearby and wondered if it might be the very same bird Lewis had seen (highly unlikely; the nest may have been replaced as well). Another government expedition reported an eagle nest and an eagle perched nearby on the same island 12 years later. "The sight of this eagle was to me one of the most peculiarly pleasant incidents of our reconnaissance." reported an engineer named Thomas P. Roberts. According to the Guinness Book of World Records, The largest bird's nest was built by a pair of Bald Eagles (Haliaeetus leucocephalus), and possibly their successors, near St. Petersburg, Florida, and measured 2.9 m (9 feet, 6 inches) wide and 6 m (20 ft) deep. "It was examined in 1963 and was estimated to weigh more than two tons (4,409 pounds).
In the early 1900s, one Bald Eagle nest in a park in Ohio was so famous that you could actually buy a postcard of a photo of the nest, even after the eagles stopped nesting there. The park, now Indian Lake State Park, is located in Lakeview, Ohio. In case you are wondering, Bald Eagles are nesting in the park again -- a century later -- on one or two islands. And they do have a maple sugar festival next week.
