Ravens in Hollywood

Back to the GP today to see how things are going. Last Sunday small twigs were being taken up to the nest. Today it was some kind of soft-looking stuff, so I guess they are finishing up. Lots of ravens in the air over the park. Took lots of photos on film since I really needed the telephoto lens. Noticed that both the Hollywood sign and Hollywood are backdrops to this nest site - these are very smart birds. Also, the two nearest known nests will be visible in the distance in some photos, that is, Iron Mountain and Runyon Canyon. I would not be surprised if there were closer nests - say, near Lake Hollywood, or on the other side of the GP, but if building season is just about over, they will be harder to find. At one point, an intruder raven appeared and was chased right off, which I hope will turn out well on film.
