I was by Friday PM and did not see the eagles, but it was evident they had been building on the nest. Specifically, there is a man-made board/stick sticking out of the nest about 3 feet or so on the east side.
I saw that man-made thing sticking out of the nest and thought I must have been seeing "things" as it was kind of reflecting the sun so it appeared to be made of metal or plastic. I tried to get a decent picture of it to see if anyone else had ever noticed it, but my pictures of it were lousy.
I got some really good (well, good for me, that is..) pics today. I'm working on them right now. I'll be sharing them shortly.
Hi Kat, in answer to your question, I'm using a Canon 7D with a 100-400mm lens. I stopped by the nest late this evening and was able to take some obstructed pics of both adults at the nest. I'll post shortly.
