A COMMON TERN was found at San Joaquin Wildlife Sanctuary in Irvine on October 12 and continued through October 16. It’s been seen flying around various ponds, but likes to perch on the sticks at the SW tip of the island on Pond 1. It’s been seen with Forster’s Terns. Photos taken over the past few days show a possible second bird that has a darker cap.
 
An adult NEOTROPIC CORMORANT was found at San Joaquin Wildlife Sanctuary on October 7 and continued through October 16. The bird moves around a bit but is most reliably found on the north side of the island in Pond 1. It may disappear for long periods of time and hide among the pelican flock in the interior of the island.

A juvenile *TRICOLORED HERON* was found at San Joaquin Wildlife Sanctuary in Irvine on October 15. It was seen initially in Pond C then moved over to Pond A. It flew off mid-morning and was not seen again. This is a CBRC review species, meaning documentation of any sightings should be forwarded to Tom Benson at secretary@....
 
A CATTLE EGRET continued at San Joaquin Wildlife Sanctuary in Irvine through October 16, where it’s pretty reliably found on Ponds C or E.
 
Up to two YELLOW-CROWNED NIGHT-HERONS continued at Bolsa Chica Ecological Reserve in Huntington Beach through October 11, where they are usually found around the "pocket pond" and the Wintersburg Channel. Up to three birds were seen at Dana Point Harbor in Dana Point on October 10 along the rocks of the harbor and in the magnolia tree next to the Nordhavn building.
 
A FERRUGINOUS HAWK continued from Arbor Park in Los Alamitos through October 12.

An ASH-THROATED FLYCATCHER was at Talbert Regional Park in Costa Mesa on October 13. No details were provided as to the location. It should be noted that at this time observers should be obtaining multiple photographs of any Myiarchus flycatchers. Ash-throated Flycatchers have mostly left, although we do have stragglers through the end of October and early November, but we are in a period where other species could occur.

A CASSIN’S VIREO was photographed at Gilman Park in Brea on October 14. It was seen along the creek and at the “water hole."

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

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
