I think the winter may be bringing larger numbers of vagrants to town. On my way to Runyon for a quick warmup for the next day’s 10-mile hike across the Verdugos, a flying circus of some 12-14 ravens suddenly passed overhead (at the very top of LaBrea Ave.) They dispersed before long, but the observation confirmed for me a less certain one from the previous Wednesday, when at about the same time in the afternoon (4 p.m. or so) a large cloud of the birds was hovering between Highland and LaBrea at Willoughby or Melrose, until one bird made a decision and flew off to the west.
I do know there are more ravens in the immediate vicinity of Runyon than previous to December.
On the way back from Runyon, three ravens were playing above Hollywood Boulevard, perching on ten story office buildings, diving off them like Mexican cliff divers, and buzzing the pigeons.
