Petaluma Nature Almanac: Birds of prey flock together

My latest (third) Petaluma Nature Almanac column for the Argus-Courier is in today's paper. It covers migratory and overwintering raptors in the area -- all 17 species off them. Thanks to Larry Broderick for sharing his expertise again (last year I also spoke with him for a similar, but shorter piece in Sonoma magazine). Find the new article right here.
