Report Details
Discovery of 5 dead birds (possibly 3 species) was unusual. COASST has identified the larger one as Large Immature Gull; waiting for their identification of the other birds' photos. Sent photos of man-made object to South Beach Park Ranger. Dead mole crabs in one area (less than 10) were new. Pacific razor clam also new. Dunes in back of houses north of Henderson Creek looked higher and on a slant -- sand been added or natural built-up by waves? Variety of plants in beach sand. More families enjoying the day observed.

Temperature: 70 F. Cloud Cover: Sunny. Wind Velocity: Moderate. Wind Direction: NW. Tide Level: 6.8 feet.
Human Activities
Number of people: 30. Number of dogs: 6. Walking or running: 10. Playing in sand: 15. Other Activities: family of 5 in driftline. Families were out with children playing in the sand. We came later than we usually do so more adults were out.
Vehicles
Notable Wildlife
Lots of birds this time. Looked like the larger birds were gulls. Couldn't identify the small shorebirds nor get close to them to photograph them.
Beached Birds
Total dead birds: 5. Photos of these birds were sent to COASST for identification. COASST identified the larger bird as a Large Immature Gull. The other birds were identified by COASST as Common Murres. See caption for each photo for further identification. A walker told us that he had seen a dead guillemot earlier in the week. Most unusual for us to find so many dead birds.
Dead Fish or Invertebrates
Unusual concentration. Mole crabs were found which was a new species for us. Broken sand dollars seen.
Driftline Content
Seaweeds and seagrass, Animal casings (e.g., crab, shrimp molt), Land-based debris (picnics, etc.), Ocean-based debris (from fishing boats, ship trash, etc.), Shells, Small rocks, Styrofoam, Wood pieces. Unusual object found near Henderson Creek; photo sent to South Beach Park ranger. Asphalt sheet.
Man-made Modifications
Dune modification/removal. It seemed that sand had been added to the dunes in back of the houses north of Henderson Creek.
Natural Changes
Previous eroded areas may be stable.

This time I concentrated on the area south of Henderson Creek where there is more activity. Photo submitted, & will be the last one. Beach was quite clean and probably because of the beach clean-up activities the previous Saturday.

A pleasant day on the beach at very low tide which exposed one large tidal pool which hadn't seen before.

We usually access the beach via an entry at Surfland which hasn't been easy in the past.
