A continuing CACKLING GOOSE was reported from Mile Square Regional Park in
Fountain Valley on August 25. The bird was associating with Canada Geese.

A WHITE-WINGED DOVE was photographed on feeders at a private residence in
Laguna Beach on August 27.

A SNOWY PLOVER was photographed on the "upper" Santa Ana River west of the
Lakeview bridge on August 26, then again west of the Imperial Highway
bridge on August 28. In Orange County this species is restricted almost
exclusively to the coastal shoreline, and any inland incursion is highly

A RUFF that was found on the Santa Ana River on August 16 continued through
August 30, most commonly just downstream of the Imperial Highway Bridge.

Up to 2 BAIRD'S SANDPIPERS were present in the groundwater recharge channel
(the channel north of the big berm) of the Santa Ana River about 1/4 mile
west of the Lakeview Bridge between August 24 and August 29. There were
several reports of up to 2 additional birds just west of Imperial Highway,
but thus far all photos that have been submitted to eBird or through
private email have been misidentifications of Least Sandpipers.

A PECTORAL SANDPIPER was found along the Upper Santa Ana River on August
23, a few hundred yards east of the Lakeview Bridge, and continued into
August 24 before apparently departing.

A SOLITARY SANDPIPER was photographed at San Joaquin Wildlife Sanctuary in
Irvine on August 30. The bird moved back and forth between Pond D and Pond
C, where it was also videotaped attacking a feather.

A LUCY’S WARBLER that was found at Huntington Central Park in Huntington
Beach on August 21 continued through August 27. It has been difficult to
find but has most often been observed working the eucalyptus trees along
Loren's Ditch, in the area immediately west of the maintenance yard.

The Orange County RBA and events summary is produced weekly by Ryan
Winkleman and Jeff Bray in collaboration with Doug Willick. Sightings of
rare birds can be posted to the OrangeCountyBirding listserv, emailed
directly to Jeff Bray (<jbray4913...>) and/or Ryan Winkleman (
<rswinkleman...>), and/or submitted to eBird (
ebird). Any supporting details (descriptions, photos, audio recordings,
etc.) of rare sightings that are not already disclosed on the listserv or
on eBird should also be emailed to Doug Willick <atdoug.willick...>

Those sightings that are included in this summary generally include those
that are considered rare (regionally or seasonally) for Orange County based
on "The Birds of Orange County: Status and Distribution" (Hamilton and
Willick), "Birds of Southern California" (Garrett and Dunn), and/or more
contemporary changes in local or regional status and distribution. Rarities
that regularly or seasonally occur at a particular location, such as
annually wintering rarities on Seal Beach National Wildlife Refuge, are not
included in this digest, but reports of these same species occurring at
other, atypical locations throughout the county may be included. All bird
reports are vetted to the extent possible prior to each publication, but in
the interest of sharing information, the accuracy of any given report
cannot always be guaranteed, nor can the presence of any given bird for
those who choose to chase after them.

Information on upcoming local events is taken largely from the Sea and Sage
Audubon website ( Sea and Sage Audubon
is based out of the Audubon House at the San Joaquin Wildlife Sanctuary in
Irvine. They sponsor a number of public field trips, special birding
events, conservation lectures, and social gatherings throughout the year.
Information regarding upcoming local events should be considered accurate
at the time of this posting. However, for the most current information
please refer to the field trip list on the Sea and Sage Audubon website at It is
also recommended that you refer to that website immediately prior to
engaging in any field trip to confirm that trips are still occurring. If
you know of additional upcoming events that are not sponsored directly by
Sea and Sage Audubon, please email Ryan Winkleman and/or Jeff Bray for
