Crows and ravens

Miller, Mark C <mark.c.miller@...>

Here in the southern San Francisco Bay area, over the years it's been very
interesting to watch ravens pushing out from the immediate shoreline into
suburban areas. Ravens have always been common in the Santa Cruz Mountains,
but down in the flatlands, even as recently as 1990 it was very unusual to
see a raven more than a mile from the bay, and now they seem to be all over.
My guess is that now that the landfills are getting capped over, the ravens
are spreading out, and have taken to nesting on the roofs of buildings.
Ravens are strangely absent from the Monterey Peninsula, but become common
and occur with crows from Big Sur south.
