> West Nile disease, which appeared in the US in 1999, knocked back the population of crows (and related species like jays) in many parts of the country. In some areas they have been coming back. I don’t know when West Nile hit San Jose, but perhaps some of the increase seen by the OP is due to recovery of the crow population in this area.

I’ve been walking dogs in the field across the street for 16 years, and this is the first year I’ve noticed crows. They’ve driven the geese and seagulls away, and appear to have driven off the sparrows who nest in our garage eaves. So they have reached Fremont also.
