The Mississippi River is mostly free of ice now, and the Bald Eagles have spread out along the river banks to begin their nesting season.
Like the Great Horned Owls, Bald Eagles seem to get a jump on rearing their nestlings by beginning their nesting season in February, despite potential torrential snow storms (like the one that hit the eastern US a few weeks ago) or bitter cold.
A territorial pair of adult eagles might use the same nest each year, building it up with sticks until it reaches quite a mammoth size. (see my post from January 31 this year). Both sexes incubate the clutch of 1-3 eggs (usually just two), which take about 35 days to hatch. While one adult is on the nest, the other searches for food, or sits protectively in a nearby tree.
This attentive behavior continues throughout incubation and for the first 2-3 weeks of nestling life, until the nestlings are more able to regulate their own temperatures and the environmental insults have hopefully abated. See an earlier post on “changing of the guard“.
Video cameras installed above nests are a great way to view what goes on inside an eagle nest. The MN Department of Natural Resources live action eagle webcam shows scattered fur/feathers and some uneaten meat in the nest, so perhaps these adults are already feeding newly hatched eaglets. The Pennsylavania Game Commission eagle live-webcam shows a sedentary eagle incubating. The nest cup there is very clean, so these eggs may not have hatched yet. You can check back every so often to view the progress of the nestlings.
