A EURASIAN WIGEON continued at Pearson Park in Anaheim through December 26.
It was seen in the pond and stream on the north side of the park. Another
was reported on December 25 from the flood control channel on Yorktown
Avenue between Magnolia and Bushard in Huntington Beach.

A COSTA'S HUMMINGBIRD was reported from Crown Valley Community Park in
Laguna Niguel on December 23. Two more Costa's Hummingbirds, a male and
female, were reported together from Ryan's house in Rancho Santa Margarita
on December 25. They wintered together last year as well and acted like an
old married couple chasing each other around his yard and bickering at his
feeders. Of course, after initially putting up a fight, the male was
eventually submissive to the female.

A minimum of 32 WILSON'S SNIPES were reported hiding in low-cut emergent
vegetation in the Peters Canyon Channel in Irvine approximately halfway
between Barranca and Warner. This seems to be far above average of what we
can expect in Orange County these days, but at the same time points out how
many more of these birds there may be than we actually typically detect
while birding.

A GLAUCOUS GULL continued at Dana Point Harbor through December 25. The
bird has most often been seen hanging on and around the bait barge off of
Puerto Place.

A BROWN BOOBY was reported flying past the Dana Point Headlands on December
23.

A *TRICOLORED HERON* continued at Bolsa Chica Ecological Reserve in
Huntington Beach through December 26. 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...>

An immature YELLOW-CROWNED NIGHT-HERON continued at Bolsa Chica Ecological
Reserve in Huntington Beach through December 27, where it continued to be
reported from the "Pocket Pond" and is now molting out of its juvenile
plumage.

A FERRUGINOUS HAWK continued near the Outdoor Education Center at Irvine
Regional Park in Orange on December 22.

A SHORT-EARED OWL was reported from San Joaquin Wildlife Sanctuary on
December 20. The bird was reported flying overhead at approximately
33.660352, -117.845557.

A HAMMOND’S FLYCATCHER continued at Mile Square Regional Park in Fountain
Valley through December 25, where it was presumably found once again in the
area east of the entry at Ward and Edinger, along the golf course edge.

Two GRAY FLYCATCHERS continued in the county this week. The first was at
Irvine Regional Park in Orange through December 27, between parking lots 2
and 3. The other Gray Flycatcher at Mile Square Regional Park in Fountain
Valley continued through December 25 in the vicinity of the entry at Ward
and Edinger.

A TROPICAL KINGBIRD continued at the Mediocre Park in Irvine through
December 22, where it has been most often seen and heard around the
reflecting ponds in the western corner of the park.

Two CASSIN'S VIREOS were reported in the county on December 27: a
continuing bird at Mile Square Regional Park in Fountain Valley, and a new
bird at Pittsford Park in Lake Forest.

A GREEN-TAILED TOWHEE was reported on December 27 from the FDA Building in
Irvine. This bird is on private property and is not chaseable.

A SWAMP SPARROW continued at Huntington Central Park in Huntington Beach
through December 27, where it was last reported in the southeast corner of
Talbert Lake.

A WHITE-THROATED SPARROW continued at Pinecrest Park in Mission Viejo
through December 23, where it is frequently found foraging around the slope
below the entrance path into the park.

A HOODED ORIOLE continued at Mile Square Regional Park in Fountain Valley
through December 22, where it was last reported in the vicinity of the Ward
and Edinger entrance.

An OVENBIRD was present at Mile Square Regional Park in Fountain Valley
through December 25, where it has most frequently been found skulking
around the northeast corner of the maintenance yard bordering the golf
course (approximately 33.717413, -117.943443).

A NORTHERN WATERTHRUSH continued at Huntington Central Park in Huntington
Beach on December 27 along "the island.”

A BLACK-AND-WHITE WARBLER continued at Huntington Central Park in
Huntington Beach on December 23, generally in the vicinity of "the island."

A NASHVILLE WARBLER was found at Huntington Central Park in Huntington
Beach on December 23, in the vicinity of the maintenance yard and the
Gothard eucalyptus trees in the northeast corner of the park.

A CHESTNUT-SIDED WARBLER continued at Huntington Central Park in Huntington
Beach through December 23. The bird has been found at the south end of the
eucalyptus trees that run along the west side of Huntington Lake.

A PALM WARBLER was at Huntington Central Park in Huntington Beach through
December 23, where it was foraging on the lawn south of "the island."
Another Palm Warbler was reported from the Santa Ana River on December 26,
in the giant tamarisk between Lincoln and Glassell.

A PINE WARBLER continued at Mile Square Regional Park in Fountain Valley
through December 21, where it was last reported off the entrance off Ward
and Edinger in the vicinity of the white wall that runs along the golf
course.

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

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.
