CACKLING GEESE were reported from Mile Square Regional Park in Fountain
Valley on November 14 and from San Joaquin Wildlife Sanctuary in Irvine
through November 15, where a pair has frequently been cited on Pond 1.
A BLACK SCOTER was reported on November 12 from within a flock of Surf
Scoters floating off the Balboa Pier, but photos have not yet been
An AMERICAN BITTERN has returned to Bolsa Chica Ecological Reserve in
Huntington Beach. It was first reported on November 3 and last reported on
November 13. Usually it’s been seen off the walkbridge from the PCH lot.
A *TRICOLORED HERON* continued at Bolsa Chica Ecological Reserve in
Huntington Beach through November 15. The bird has been moving around to
different areas including the footbridge by the PCH lot, the channel going
along “Rabbit Island,” and the “Pocket Pond.” *** Because Tricolored Heron
is a CBRC Review Species, please send documentation to the CBRC Secretary
Tom Benson at <secretary...>
A presumably continuing YELLOW-CROWNED NIGHT-HERON was reported from Bolsa
Chica Ecological Reserve in Huntington Beach on November 13.
A PLUMBEOUS VIREO first reported at Craig Regional Park in Fullerton on
October 28 continued through November 14. It has been most often seen
making rounds through the pines surrounding the ranger station at the park
A BROWN CREEPER continued at Carbon Canyon Regional Park in Brea through
November 12. The bird is typically found in the pines both east and west of
the tennis courts, and seemingly is most reliable in the mornings. Given
its cryptic nature, it may be most easily found when it is vocalizing .
A GOLDEN-CROWNED KINGLET was found at Craig Regional Park in Fullerton on
November 12 and was last reported on November 15. The bird was found
frequenting the pines surrounding the ranger station at the park entrance,
where it was vocalizing quite loudly.
A VARIED THRUSH was found at Carbon Canyon Regional Park in Brea on
November 11 and continued through November 12. The bird was typically seen
on the eastern side of the tennis courts, occasionally dropping into the
grassy area under the pines.
A RED-THROATED PIPIT was found on October 31 and continued through November
14 at San Joaquin Wildlife Sanctuary in Irvine. The bird has been
associating with a flock of several dozen American Politics in the
northeast corner of Pond C.
PINE SISKINS continue a slow irruption into Orange County this fall, with
two birds hanging out around my house in Rancho Santa Margarita on November
11. They will presumably become more common throughout the county as the
A probable CHESTNUT-COLLARED LONGSPUR was photographed at Bolsa Chica
Ecological Reserve in Huntington Beach on November 10. The bird was
associating with a flock of Horned Larks in the fenced nesting preserve on
the far side of the walkbridge, and was only present for a short period of
time before it left and was not seen again. Photos were generally
insufficient to definitively identify the bird, though based on primary
extension and the pattern of white in the tail it was thought to probably be a
Chestnut-collared Longspur, which has become exceptionally rare in Orange
County since the development of the Plano Trabuco for the City of Rancho
Santa Margarita in the 1990s. However, because of the quality of the
photos, the outside chance remains (but small) that this bird could have
been a SMITH'S LONGSPUR, which would otherwise have been the first record
for Orange County.
A SWAMP SPARROW was reported from Huntington Central Park in Huntington
Beach on November 8 and continued through November 14. It was seen to the
northeast of the fenced-in garden area along the edge of the lake in the
A SUMMER TANAGER was reported from Huntington Central Park in Huntington
Beach on November 10, but no location details were provided.
A late--and potentially winter--HOODED ORIOLE was photographed at Mile
Square Regional Park in Fountain Valley on November 14. The bird was seen
in eucalyptus trees around the intersection of Ward and Edinger.
A NORTHERN WATERTHRUSH continued at Huntington Central Park in Huntington
Beach through November 13 in the same general vicinity as the Swamp Sparrow.
A BLACK-AND-WHITE WARBLER was reported from Huntington Central Park in
Huntington Beach on November 11.
A CHESTNUT-SIDED WARBLER was at Huntington Central Park in Huntington Beach
on November 15. The bird was photographed at the south end of the
eucalyptus trees that run along the west side of Huntington Lake.
A PALM WARBLER was photographed in agricultural fields west of the
intersection of Alipaz and Via Positiva in San Juan Capistrano on November
A PINE WARBLER was at Mile Square Regional Park in Fountain Valley on
November 13 and 14. The bird seems to move around a good deal and was first
seen on the 13th in pines near Ward and Edinger and on the 14th at 33.727115,

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 (
http://ebird.org/content/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 at <doug.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 (http://www.seaandsageaudubon.org/). 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
http://www.seaandsageaudubon.org/FieldTrips/FieldTripSchedule.html. 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
