This Santa Cruz Bird Club field trip visited Natural Bridges State Beach and some adjacent areas. Starting with a singing CALIFORNIA THRASHER in the willows just southeast of the Delaware Avenue gate and a pair of AM. KESTRELS in the pines nearby, we worked our way down to the "trail marker #5" area, where there was a notable flurry of activity involving dozens of birds in the eucalyptus, pines and willows: YELLOW-RUMPED and TOWNSEND'S WARBLERS, RUBY-CROWNED KINGLETS, CHESTNUT-BACKED CHICKADEES, PYGMY NUTHATCHES, and many of their usual associates, plus lots of finch and sparrow activity (a majority Golden-crowned) in the adjacent scrubby area. A little farther down the trail an adult RED-SHOULDERED HAWK rushing out of the eucalyptus pursued by an adult RED-TAILED HAWK was an impressive site in the early morning light. The rarest bird of the morning, for the season, was a very late female/immature BLACK-HEADED GROSBEAK, that was calling in the eucalyptus grove near the bend in the entrance road, then flew off toward Swanton Blvd. HOUSE WRENS were still in good numbers around the park, with at least 4-5 for the morning. In the Moore Creek area of the park Kathy Kuyper spotted a RED-BREASTED SAPSUCKER in the eucalyptus near Delaware Avenue, which eventually came into clear view.
We heard a NUTTALL'S WOODPECKER in a couple of different spots, but probably the same bird moving around.

The beach added many expected species. Two BLACK TURNSTONES foraging among six KILLDEER well up on dry sand near the lagoon seemed a little out of character, but there were especially large numbers of kelp flies around little patches of seaweed in this area.

At least 20 BLACK-BELLIED PLOVERS were on the rocky shore west of the beach. Three MEW GULLS were among other gulls swimming just off the beach, but we didn't manage to find any Heerman's, another sign of changing seasons.
At Antonelli Pond a very recently-hatched young PIED-BILLED GREBE was riding around on the back of one of its parents, sheltered under its wing, then later was swimming around and receiving its share of a crayfish meal. It looked like another late grebe nest may have been in progress; we'll see what happens with that one. One SORA called briefly. Passerines were quiet by the time we got to the Homeless Garden, but there were a couple of TURKEY VULTURES to the north, and WHITE-TAILED KITES and a more distant NORTHERN HARRIER to the west. Altogether we ended up with 81 species for the morning.
