Bev, the white structure next to the nestbox that you mentioned, I saw a white structure that looked like a platform with rails for the biologists to stand on - I don't recall anything else. Also, I found it easy to look at the ravens and the nestbox from the ground as there are a number of barricades around, which reduce traffic and people. This was good, as it prevented me from running into people and cars. Certainly your viewpoint from the parkade would be better, though, and I must remember that for next time. I would be happy to find out from you the best spots for watching the falcons.
