BIRDS MENTIONED

Ruff

Reddish Egret

Yellow-crowned Night-Heron

Swainson's Hawk

Yellow-headed Blackbird

Northern Waterthrush

Black-and-white Warbler

Rose-breasted Grosbeak


A WHITE-WINGED DOVE was recorded at a private residence in Anaheim on September 7. We also received a late report of a bird in Laguna Beach on September 1. September tends to be the month where this species is most likely to pop up in the county, so keep your eyes open for those white wing linings!


A RUFF continued on the upper Santa Ana River through September 10, where it has been continuing downstream of Lakeview Avenue again.


An out-of-place REDDISH EGRET continued in San Diego Creek in Irvine through September 11. It is usually seen somewhere along the creek between Main and Barranca. 


At least four YELLOW-CROWNED NIGHT-HERONS continued at Bolsa Chica Ecological Reserve in Huntington Beach through September 10 (usually around the "pocket pond" and the Wintersburg Channel), at least two birds were at Dana Point Harbor through September 6 (usually near the Nordhavn building and in the large magnolia trees across the street), and two birds were found at a new location at Victoria Pond at Talbert Nature Preserve in Costa Mesa on September 8.


Two SWAINSON'S HAWKS (one adult and one juvenile) continued to be observed in Seal Beach along the I-405 right-of-way through September 10. They are typically found perching on lampposts, flying over Naval Weapons Station Seal Beach, or flying over Old Ranch Golf Course/Los Alamitos Joint Forces Training Base and can be seen pretty reliably from the Seal Beach Tennis Club parking lot when they are around. The younger juvenile has not been verifiably seen since August 15, and the adult female has not been seen since August 28.


A NORTHERN WATERTHRUSH was found in Huntington Central Park in Huntington Beach on September 7 and continued through September 10. It has been seen along the northern and northwestern edges of Talbert Lake. 


A BLACK-AND-WHITE WARBLER was at Talbert Nature Preserve in Costa Mesa on September 8.


A ROSE-BREASTED GROSBEAK was in some elderberry at Mile Square Regional Park in Fountain Valley on September 11. Happy hunting!



LOCAL EVENTS


UPCOMING EVENTS THAT DO NOT REQUIRE ADVANCE RESERVATIONS


Sea and Sage is sponsoring a trip to southern San Diego County and the Tijuana River Valley on September 14 from 8:00am to 12:00pm or possibly as late as 3:00 or 4:00pm. The directions are more complicated than I want to reproduce or copy, so see here if interested: http://www.seaandsageaudubon.org/FieldTrips/fieldtripscurrent.htm#SouthSanDiego


The Bolsa Chica bird walk will take place on September 19 at Bolsa Chica Ecological Reserve in Huntington Beach from 8:00am to 12:00pm. Meet at the main parking lot at nearby Harriett Wieder Regional Park.

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


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 Ryan Winkleman separately for consideration to be mentioned in the current quarterly report for North American Birds.


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, may not be included in this digest, but reports of these same species occurring at other, atypical locations throughout the county may be included. We don't include hybrids, subspecies, introduced or exotic birds, or in most cases and for no real reason, geese. 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
