What a fine crew of fourteen talented, enthusiastic birders on this Pescadero field trip. We first concentrated our efforts on the ocean and beach rocks off of the ridge in the middle parking lot, from which we saw a Peregrine Falcon, some close-up Caspian Terns, and quite a few species of waterfowl and shorebirds. We then took an extended walk along the full Water Lane trail for land birds and raptors. The highlight there was a Western Kingbird, an uncommon migrant in the coastal areas. Overall we saw 76 species, as listed below. Thanks to Donna Pomeroy for permission to share her sharp pictures of the event.
