Black Oystercatcher chicks spotted on Aramburu Island

Black Oystercatchers have nested on Aramburu Island for the fourth year since major shoreline enhancement was completed. This year three chicks hatched! 

All three eggs hatched on or about June 21st, and three downy hatchlings were seen stumbling about the nest area soon after. Black Oystercatchers can lay up to three eggs, but two is more common.  Previous clutches on Aramburu, from what we believe to be the same pair of adult birds, have been limited to two eggs.  

As of July 19, we see only two of the three chicks, but both are eating well and looking healthy.  The young birds are about four weeks old at this point, and are likely to be able to fly (fledge) within a week or two.  Fledged birds will continue to stay with the parents for months, honing their feeding skills.

Shoreline reconstruction on Aramburu Island took place in late 2012, and oystercatchers made their first attempt at nesting in the spring of 2013.  The success of their breeding attempts points to the promise of such shoreline enhancement projects in other parts of the Bay and beyond!

That's a California Scrub Jay to you, mister

Our friends at Audubon Magazine have a nice overview of the new official bird checklist from the American Ornithologists' Union. Jumping out at us is the new split of the Western Scrub Jay into two species, the California Scrub Jay and the Woodhouse's Scrub Jay. The California Scrub Jay isn't a total endemic, however, covering ground from Baja to Washington State. But, hey, we'll be happy to call it our own. And we'll continue to remind our friends that the spunky blue bird they saw in Los Angeles was not a Blue Jay.
