Late Wednesday night, 26 February, at 11:15pm a raccoon climbed the bald eagles’ nesting tree at Hays while a noisy train rumbled by in the valley. Mother Eagle was asleep but she heard the raccoon’s rustle and stood up to defend her three eggs. As the mammal crested the nest edge she opened her wings and took a few steps toward it. The raccoon turned and fled.
When you watch the encounter on this archived video from PixController you can see everything that’s going on, but the participants can’t. The nest is lit at night by an infrared lamp mounted near the distant camera. The camera is able to see infrared light but we humans, the eagle, and the raccoon cannot. On that overcast night the animals were dark shapes to each other. I’m sure the raccoon was frightened to find an eagle!
Raccoons raid songbird nests because the songbirds are powerless to stop them but they avoid raptors because birds of prey will kill them. Why was this raccoon attracted to a bald eagles’ nest?
Scott Kinsey gave us the hint on PABIRDS yesterday morning when he wrote:
It has been fun watching the Bald Eagle nest cam from Pittsburgh. Finally got to see a feeding. I think it was the male brought a fish for the female at 10:39am. She had it done by about 10:47 and back on the eggs. Might have been a Gizzard Shad around eleven inches?
As Scott points out, the female eagle eats at the nest and though she sets the scraps aside she doesn’t take out the garbage. Lots of smelly fish scraps are up there on the sticks. The raccoon probably smelled the leftovers and came exploring for a meal. When he realized his mistake he was out of there!
This surely isn’t the first time a raccoon has explored an eagles’ nest at night. We just happened to see it because of the night vision camera. He was lucky he didn’t make a fatal error.

p.s. This episode points out another difference between bald eagles and peregrines. Adult peregrines don’t eat at the nest during incubation and even when feeding nestlings in the nest they take out the garbage.
Post Gazette posted on facebook that they had another interloper yesterday or today. Said it appeared to be a hawk or immature eagle, though it only appears briefly on the camera.

Yesterday’s visitor looks like a juvenile bald eagle, probably the one who’s been spotted and photographed hanging around Beck’s Run in the past week. This is *not* last year’s “Baby” since the plumage, bill color, etc., shows it to be about 3 years old. Just a passing teenager, and the Hays adults are certainly aware of it and will nudge it out of their territory (Get off our lawn, kid!)
It didn’t come to the nest, just a pretty close fly-by. Remember there’s a 30-yard space between the camera and the nest tree!
You’re right. Eagles just bury their garbage by putting more grass and sticks on the bottom of their nests. Watching the WebCam one can see the incubating bird find a scrap or two in the nest and eat it. The smell must have attracted that raccoon.
It’s interesting, after watching the Cornell heron cam the past 2 seasons, herons seem to be much better at cleaning fish scraps out of the nest although I seem to remember lots of wasps and other bugs. 😉 But the response to night predators (GHO in the herons’ case and much more intense interaction) is quite startling in any case. Thanks for the video!
