CALLIOPE HUMMINGBIRDS in the county this week included a male at Ryan’s house in Rancho Santa Margarita on April 17 and a female on the same day, also in Rancho Santa Margarita, in Chiquita Canyon along the Westridge Trail. Another five birds were reported on April 22 in Silverado Canyon, bringing the county's total number of birds this spring to a conservative 16 or as many as 19, either of which is a new seasonal record for Orange County (the previous record was 12-15 in spring 2014). Hooray!

A *TRICOLORED HERON* continued at Upper Newport Bay in Newport Beach, on April 18. This is a CBRC review species and all documentation should be forwarded to Tom Benson at secretary@....
A DUSKY FLYCATCHER was reported from Silverado Canyon on April 22. It was seen just past the third creek crossing near GPS: 33.753881, -117.566096.
A BROWN-CRESTED FLYCATCHER that was found in the willows off Chrisanta north of La Paz on December 27 continued through April 22.

A BANK SWALLOW was at San Joaquin Wildlife Sanctuary in Irvine on April 18 and continued through April 21. It was seen on Pond 2. If anybody can actually get photos, that would be appreciated.

A BROWN THRASHER continued at Aurora Park in Mission Viejo through April 19 in the southeast section of the park where the large Brazilian pepper tree is growing near the top of the windy trail down to the lower section. Ryan would very much like people to take photos of this bird, as the last several eBird reports have had crappy documentation and documentation standards should remain high particularly as it gets closer to this bird finally moving on.

A TOWNSEND’S SOLITAIRE was reported from the Bluejay and Falcon Group Campground areas on April 21. A little late for this species to be around.

A GREEN-TAILED TOWHEE was seen in Silverado Canyon up past Bigcone Spring on April 22.

Twenty-three YELLOW-HEADED BLACKBIRDS were reported at the Naval Weapons Station Seal Beach on April 18.

An adult male ORCHARD ORIOLE found at Bartlett Park in Huntington Beach on April 1 continued through April 21. It has frequently been found around the Newland House.

A BLACK-AND-WHITE WARBLER continued at Aurora Park in Mission Viejo on April 18.

A male ROSE-BREASTED GROSBEAK was photographed in Ladera Ranch on April 16.


All Sea and Sage Audubon sponsored field trips have been canceled through at least May 1 due to cautionary measures regarding the coronavirus.


Nothing new scheduled at this time.


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 (jbray3928@...) and/or Ryan Winkleman (rswinkleman@...), and/or submitted to 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 ( 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 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
