Wedgetail, Canadian laws are very strict about not disturbing active eagle nests and the CU cam can only be cleaned when the eagles leave the nest during August and September
and go to the salmon runs. After they are gone, Doug hires a tree climber to go up there and clean the CU cam lens.
Otherwise the rain that manages to get on that CU cam and the Wide Angle cam is the only way they get clean. The dead part of the tree stump above the nest is too unstable for the tree climbers to risk cleaning the Wild Angle cam now. (The rest of the tree appears to be in good health.)
Last year the eaglet named Hope sent a "poop shoot" and it obscured the view so that only the Wide Angle cam could be used for the rest of the season!
Phoenix has done it several times, but so far, thanks to the rain and good fortune, the CU cam is still being used.
Plans are underway to make some changes to where the cams are seated when the eagles leave for their annual salmon festival. We hope to avoid the "poop shoot" scenarios that way and make it easier to keep the cams clean.
