Gary and I took a little trip yesterday to explore the beach just north of Imperial Beach and south of Silver Strand State Beach. A lot of organic material had washed ashore, including masses of California Mussels, as well as much kelp.
Some of the mussels had Leaf Barnacles attached.
This is a beach popular with clammers due to its concentration of Pismo Clams. What I presumed to be immature clam shells were here and there on the shore.
Most of the shells on this beach are heavily wave-worn, like this Chestnut Cowrie.
The beach was surprisingly bird-filled, with Willets, Marbled Godwits, and Forster’s Terns being present in numbers (the Forster’s Terns in large numbers as they fished in the huge anchovy schools off shore). We also saw the occasional Royal Tern in full breeding plumage. A lone Long-billed Curlew graced the beach and we saw several more in the Tijuana Estuary area later.
We saw easily over a half dozen Snowy Plovers skulking in the higher, drier portions of the beach as well. Signs discourage people or dogs from walking in their territory, but no fences exist, as we saw in Oregon last month for the protection of this species. The plovers are extremely well camouflaged, and tend to move in short bursts of activity, as opposed to just meandering around as the Willets do.
We also saw a merganser hanging around the edge of the water, and occasionally entering the shallows. A scoter (probably a Surf Scoter) was seen fishing in the shallows, as well.
