A BLACK TERN continued at Bolsa Chica Wetlands in Huntington Beach through October 1. It’s been seen flying around over the “pocket pond."

A *RED-FOOTED BOOBY* was photographed by a whale watching boat on October 1. This is a CBRC review species, meaning documentation of any sightings should be forwarded to Tom Benson at secretary@....

An out-of-place, inland REDDISH EGRET continued in San Diego Creek in Irvine through October 1. It is usually seen somewhere along the creek between Main and Barranca.

Up to two CATTLE EGRETS continued at San Joaquin Wildlife Sanctuary in Irvine through October 2, with reports on Ponds C and E and along San Diego Creek.

At least two YELLOW-CROWNED NIGHT-HERONS continued at Bolsa Chica Ecological Reserve in Huntington Beach through October 1 (usually around the "pocket pond" and the Wintersburg Channel), and at least two birds were at Dana Point Harbor through September 29 (usually near the Nordhavn building and in the large magnolia trees across the street). A single immature bird was photographed at Talbert Nature Preserve in Costa Mesa on September 28.

Two SWAINSON'S HAWKS continued to be observed in Seal Beach along the I-405 right-of-way through October 1. 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. Please note that we are in active fall migration for this species, and that observers and eBird reporters should be extremely careful to identify the individual birds on or around the base if seen. We are very interested in determining when our local birds leave, so if you cannot see a leg band or surmise from behavior that a given bird(s) is one of the summer 2019 birds, please do not assume that it is, and please make notes regarding as such.

A PLUMBEOUS VIREO was reported from Gilman Park in Brea on October 1. It was seen at the “bathing spot." No photos have been provided.

A RED-BREASTED NUTHATCH that was found last week at Turtle Rock Nature Center in Irvine on September 24 continued through September 26. Another bird was at a private residence in Laguna Niguel on September 30. This species was absent from the county last fall/winter, so with these early sightings, it could be a good fall/winter for them here this season.

A BLACK-CHINNED SPARROW was photographed in Limestone Canyon on September 28. This species is usually gone from the area by the end of August.

A BREWER'S SPARROW continued at Huntington Central Park in Huntington Beach through October 2. It has been found generally on the lawn east of "the island."

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

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 or 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
