A SNOW GOOSE was present at Centennial Park in Santa Ana on November 8.

A ROSS'S GOOSE was present at San Joaquin Wildlife Sanctuary in Irvine
through November 7. It was frequently seen on the Pond 1 island as well as
the open water of Pond C.

An AMERICAN BITTERN has returned to Bolsa Chica Wetlands in Huntington
Beach. It was first reported on November 3 and last reported on November 8.
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 7. 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 GOLDEN EAGLE was photographed in Aliso Viejo on November 3. It was seen
soaring over the north end of Aliso Viejo County Club. This species is
particularly notable whenever it is seen away from the Santa Ana Mountains
or adjacent foothills.

A BALD EAGLE was reported along the Santa Ana River in Anaheim on November
3. This is presumably the same individual returning for its third winter
since early 2016.

A ZONE-TAILED HAWK was photographed over Casta del Sol Golf Course in
Mission Viejo on November 3 and again over O’Neill Regional Park in Trabuco
Canyon / RSM on November 7 and November 8, where it apparently flew low
over Ryan's house hoping to be caught high-fiving him in selfies, but alas
he was at work at the time...given the proximity of these areas, this is
probably the same hawk roaming up and down the Arroyo Trabuco and adjacent
areas.

A FERRUGINOUS HAWK was reported in the Villa Park Flood Basin in Orange on
November 5. There was also another one reported from Seal Beach National
Wildlife Refuge on November 5, where they often show up every year around
this time.

A PACIFIC GOLDEN-PLOVER was reported from Seal Beach National Wildlife
Refuge on November 6.

Three COMMON GROUND-DOVES were reported from Fairview Park in Costa Mesa on
November 5.

A PRAIRIE FALCON was reported from Seal Beach National Wildlife Refuge on
November 5 and again on November 6.

A CASSIN'S VIREO was reported from Silverado Canyon on November 3. It was
heard and seen along the creek about half way up the paved section of the
Maple Springs Truck Trail.

A possible PLUMBEOUS VIREO was reported from Santiago Park Nature Reserve
in Santa Ana on November 8. It was seen about 200 feet east of the visitor
center. The bird's true identity could not be confirmed from live looks or
photographs and it is uncertain if it was truly a Plumbeous Vireo or a late
Cassin's Vireo.

A RED-THROATED PIPIT was found on October 31 and continued on November 8 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 Pilot in Orange County since 2007.

A LAPLAND LONGSPUR was reported from Seal Beach National Wildlife Refuge on
November 6. It was seen associating with a flock of Horned Larks.

A VESPER SPARROW was reported from Irvine Regional Park in Orange on
November 3. It was seen with a large flock of White-crowned Sparrows and
Dark-eyed Juncos near Lot 19.

A SWAMP SPARROW was reported from Huntington Central Park in Huntington
Beach on November 8. It was seen to the northeast of the fenced-in garden
area along the edge of the lake in the bulrushes.

A GREEN-TAILED TOWHEE continued through November 8 at Harriett Wieder
Regional Park in Huntington Beach. The bird was last reported working in
the litter at the west end of the children’s fenced area.

A female-type SUMMER TANAGER was reported from Santiago Park Nature Reserve
in Santa Ana on November 8. It was seen in the trees about 50-100 feet east
of the visitor center.

PINE SISKIN have moved in at Borrego Park in Foothill Ranch. This flock was
first reported on November 3 and continued through November 7, where they
were generally seen feeding in the sweetgum trees around the edge of the
park. This species was notably scarce last winter but so far is being
reported throughout the region this fall/winter.

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
inclusion.
