A CACKLING GOOSE continued to roam around Mile Square Regional Park in
Fountain Valley through October 5, where it’s been seen off and on through
the last few months. This bird is probably a resident who never leaves
Orange County.

Up to two PECTORAL SANDPIPERS continued at San Joaquin Wildlife Sanctuary
in Irvine through October 10. This species is usually found on Pond C but
this year they have often been seen on Ponds C, D, or E.

A LONG-TAILED JAEGER was spotted offshore during the San Bernardino Valley
Audubon Society pelagic trip on October 7.

Three different SABINE'S GULLS were documented offshore during the Sea and
Sage pelagic trip on October 6.

An ARCTIC TERN was photographed offshore during the Sea and Sage pelagic
trip on October 6. This is the first in the county since 2015.

A BULLER'S SHEARWATER was photographed offshore during the Sea and Sage
pelagic trip on October 6. This is the first sighting of this species in
Orange County since 2009, and only the fourth record for the county. A
Buller's Shearwater was seen again during the San Bernardino Valley Audubon
Society pelagic trip on October 7, skirting the county line between Orange
and San Diego Counties.

A BROWN BOOBY was seen off of the Huntington Beach Pier on October 6.

A *MASKED/NAZCA BOOBY* was photographed offshore on Platform Ellen during
the Sea and Sage pelagic trip on October 6. This is a CBRC review species,
and any photographs or details of this sighting or others should be
forwarded to the CBRC Secretary, Tom Benson, at
<secretary...>

A RED-FOOTED BOOBY presumably continued offshore on Platform Eureka during
the Sea and Sage pelagic trip on October 6. This bird was first
photographed at this location on September 29. This is a CBRC review
species, and any photographs or details of this sighting or others should
be forwarded to the CBRC Secretary, Tom Benson, at
<secretary...>

A LITTLE BLUE HERON has been hanging around in Dana Point since October 6
and was last documented on October 8. This is a very young bird that is
still nearly entirely in its white plumage, but has dark tips to its
primary feathers when viewed closely enough. The bird has been seen
alternately at Salt Creek/Monarch Beach and Dana Point Harbor.

Four YELLOW-CROWNED NIGHT-HERONS continued in the county in the last week,
with up to two continuing at Bolsa Chica Ecological Reserve in Huntington
Beach through October 7 and up to two continuing at Dana Point Harbor
through October 8. The Bolsa birds are generally found in the "pocket
pond," while the Dana Point birds are typically found around the Nordhavn
building (check the koi pond, the eucalyptus trees, the docks in back, and
the nearby jetty).

A TROPICAL KINGBIRD first found at San Joaquin Wildlife Sanctuary in Irvine
on October 6 continued at nearby Mason Regional Park on October 8. The
assumption is that this is a returning bird from last year, which was
itself assumed to range widely between San Joaquin Wildlife Sanctuary,
Rancho San Joaquin Golf Course, and Mason Regional Park.

A CASSIN'S VIREO was found at Huntington Central Park in Huntington Beach
on October 10. The bird was in the area south of the Park Bench Cafe.

A PLUMBEOUS VIREO presumably continued at Huntington Central Park in
Huntington Beach on through October 9. The bird seems to range widely so
may be difficult to find.

A MOUNTAIN CHICKADEE continued at Huntington Central Park in Huntington
Beach through October 10, where it is typically found in the eucalyptus
trees between the amphitheater and "the island."

Up to 3 WHITE-BREASTED NUTHATCHES were at Huntington Central Park in
Huntington Beach through October 10. These have typically been found in the
eucalyptus trees around "the island," as well as around "Loren's Bench,"
located just northeast of the Park Bench Cafe.

A VESPER SPARROW was photographed at Harriet Wieder Regional Park in
Huntington Beach on October 7. The bird was on the path that goes out to
the helipad.

A GREEN-TAILED TOWHEE continued at Harriet Wieder Regional Park in
Huntington Beach through October 7, where it was seen around Fisher’s
Gulch. A new Green-tailed Towhee was found at Caspers Regional Park along
Ortega Highway on October 8 and was last seen on October 11 near the park
entrance booth.

A YELLOW-HEADED BLACKBIRD was seen flying over Pond B at San Joaquin
Wildlife Sanctuary in Irvine on October 6.

A NORTHERN WATERTHRUSH continued at Gilman Park in Fullerton on October 4.
It was seen working the creek through the park. Another continued at Huntington
Central Park in Huntington Beach through October 9, where it was heard from
the vegetated interior of Talbert Lake.

A TENNESSEE WARBLER continued at Mile Square Regional Park in Fountain
Valley through October 4, where it was last seen in the "fertile crescent"
area on the northeast side of the park.

An AMERICAN REDSTART continued at San Joaquin Wildlife Sanctuary in Irvine
on October 6, where it was in the Tree Hill area.

A CHESTNUT-SIDED WARBLER was found at Yorba Regional Park in Anaheim on
October 6, where it was seen in trees at the far east end of the
easternmost parking lot.

A BLACKPOLL WARBLER continued at Mile Square Regional Park in Fountain
Valley through October 4, where it was last seen in the "fertile crescent"
area on the northeast side of the park.

A PALM WARBLER was photographed in the dry part of Pond C of San Joaquin
Wildlife Sanctuary in Irvine on October 7.

*****************************************************

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 <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 (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
inclusion. #RBA
