Ravens like to nest on cliff faces, but in L.A., the next best thing is a cliff-like building. I have been keeping an eye on the massive Iron Mountain building on Highland (a.k.a. LA’s largest billboard, but home as well to Jim Henson and Dodgers archives), for some time, but had been disappointed. Until today. It was a beatiful sunny day, cool and crisp after a night of rain showers, and the resident ravens (or at least one of them) was flying around Iron Mountain with the easy familiarity of ownership. It didn’t take long to spot the nest. This site can’t be more than three miles from the nest in Runyon, and so maybe it’s possible to begin to get an idea of breeding territory density.
