Snowy Plovers Again Nest on Surfrider Beach

Adult Snowy Plover, Malibu Lagoon (Randy Ehler 5-27-18)
Major Malibu Surfrider Beach news again this year are the nesting Snowy Plovers. Nesting behavior was first noted on April 8, 2018. As of our May 27 field trip, there were two large and well-plumaged young, attended by one adult, presumably the father (the mother leaves a few days after the last egg hatches).
Our diligent Snowy Plover (SNPL) mavens Grace Murayama and Larry Loeher supplied this Snowy Plover Activity timeline.
April 8, 2018: Volunteer Sandy Summer observes and reports possible nesting behavior.
April 9: Ornithologist Dan Cooper checks and agrees; observes adult picking at shells and settling on probable nest.

April 17: 1 adult on nest, another foraging on sand east of nest site.
April 26: Stacey Vigallon confirms 3 Snowy Plover chicks at Malibu.
April 27: Grace & Larry observe 3 chicks, 5 adults. They also observe 1 of the adults repeated returning to a different spot, photos confirm eggs in a 2nd nest site at that spot.
April 28: Tom Ryan confirms two additional eggs on the 2nd nest; Tom moves ME from 1st nest site to 2nd nest site.
May 4: Larry & Grace again observe 3 chicks, 5 adults, and 1 adult sitting on nest inside ME.

May 21: Grace & Larry observe 2 chicks, 2 adults. Lagoon water level, continually rising behind the closed barrier sandbar, has now inundated the ME and the 2nd nest.

Malibu is not the only L.A. County location for nesting Snowy Plovers. On Sunday, May 27, three Snowy Plover puffball chicks were confirmed at Dockweiler where they nested last year.

As yet there are no Least Terns nesting on Surfrider Beach, but fish-bringing courting behavior has been seen. The beach seems slightly higher than last year by a couple of inches, so perhaps any tern nests that appear won’t be inundated by high tide surf as they were last year.
