This is the Orange County, CA weekly Rare Bird Alert (RBA) and local events
summary. California Bird Records Committee (CBRC) review species are
capitalized and marked with asterisks below. All documentation of review
species should be forwarded to the CBRC secretary, Tom Benson, at
A ROSS'S GOOSE was present in the inner bay at Bolsa Chica Ecological
Reserve in Huntington Beach from October 26-27. Another goose was
well-photographed often on the Pond 1 island at San Joaquin Wildlife
Sanctuary in Irvine from October 28-31.
CACKLING GEESE were present throughout the week at Mason Regional Park (1),
San Joaquin Wildlife Sanctuary (up to 2), and Irvine Valley College (up to
7) in Irvine, and at Mile Square Regional Park (up to 8) in Fountain Valley.
A PECTORAL SANDPIPER found on October 14 continued through October 29 at
Harriett Wieder Regional Park in Huntington Beach. The bird was in the
ponds below the bluffs at Wieder.
A LONG-BILLED DOWITCHER was photographed randomly chilling in the grass at
Craig Regional Park on October 28, outside of its expected habitat in
wetlands or riverine areas.
An apparent adult FRANKLIN'S GULL was found at Bolsa Chica Ecological
Reserve in Huntington Beach on October 26. This one-day wonder preferred to
lounge around with other gulls at the far north end of the inner bay.
A *TRICOLORED HERON* continued at Bolsa Chica Ecological Reserve in
Huntington Beach through October 28. 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 remarkable second ZONE-TAILED HAWK, this time an adult (previously an
immature bird), was photographed at San Joaquin Marsh in Irvine on October
29. This bird is not typically seen in Orange County away from our
foothills (like in the beautiful Rancho Santa Margarita area 😍).
A presumably continuing TROPICAL KINGBIRD was photographed in the trees
east of the secret garden at Huntington Central Park in Huntington Beach on
A CASSIN'S VIREO was reported at San Joaquin Wildlife Sanctuary in Irvine
on October 27.
A PLUMBEOUS VIREO continued at Mile Square Regional Park in Fountain Valley
through October 29. This bird has been very difficult to find, and this
week was seen moving between the southwest corner of the Nature Center and
the pines lining the golf course. A second bird was photographed at Craig
Regional Park in Fullerton on October 28, south and downhill of the ranger
station in pines.
A BROWN CREEPER continued creeping at Carbon Canyon Regional Park in Brea
on October 28, where it was last reported on the southeast side of the
tennis courts in the conifers running alongside the creek.
An unusually late SWAINSON'S THRUSH was photographed in a residential yard
in Costa Mesa on October 26-27. This species has usually left the region by
the second week of October.
A RED-THROATED PIPIT was found on October 31 and continued on November 1 at
San Joaquin Wildlife Sanctuary in Irvine. The bird associated with a flock
of several dozen American Pipits in the northeast corner of Pond C. They
frequently flush and fly up in the air, sometimes going over the cinder
block wall and not immediately returning. This is the first verified
Reld-throated Pupit in Orange County since 2007.
A GREEN-TAILED TOWHEE continued through October 29 at Harriett Wieder
Regional Park in Huntington Beach. The bird was last reported from the end
of the fence coming down off Seapoint, in the Fisher's Gulch area.
A YELLOW-HEADED BLACKBIRD was photographed at San Joaquin Wildlife
Sanctuary in Irvine on October 27, foraging in Pond E.
A TRICOLORED BLACKBIRD was reported with the Brewer's Blackbird flock at
Centennial Park in Santa Ana on October 31. Another bird seen in a mixed
blackbird/starling flock at Mile Square Regional Park in Fountain Valley on
October 30 was also thought to likely be a Tricolor but was not confirmed.
Two NORTHERN WATERTHRUSHES were reported from Huntington Central Park in
Huntington Beach through October 28. The HCP birds are most commonly
reported from "the island," the Loren's Ditch area, and the pond behind the
library. Another Northern Waterthrush continued at Mason Regional Park in
Irvine through October 28, in the creek that parallels University Avenue.
A BLACK-AND-WHITE WARBLER found on October 12 continued through October 28
at Huntington Central Park in Huntington Beach. The bird was presumably
seen around the south end of Talbert Lake where it has been previously.
Another bird was reported at Mason Regional Park in Irvine through October

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
