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
