San Diego County Avian Database, 2002-2024, Update

10:15 am

For the past five years I have been working on
a “San Diego County Avian Database 2002-2024.” With baseline
assistance provided by Guy McCaskie and Phil Unitt, and also with input from
many additional San Diego County birders, past and present, the latest version
of this missive has now been posted on-line. This updated database includes
avian records from late 2002 to mid-June 2024—essentially since the
pre-publication cut-off date of records for the San Diego County Bird Atlas
by Philip Unitt (2004). Also included are many pre-2002 records of interest not
found in, or data-corrected from, Unitt (2004) and Unitt (1984; The Birds of
San Diego County
). The data include those involving rarities, unseasonal
records, high counts, early and late dates, specimens of interest, range
expansions and contractions, and some other significant population trends. Each
species entry is divided into four principal “sub-regions” of the
county—coast, inland, mountains, and desert–and these sub-regions are further
sub-divided into three seasons—migration, winter, and summer/breeding.

With much-appreciated assistance provided by Jane Mygatt and Natalie
Shapiro, the latest version of the database has been posted in a WORD version
on the Buena Vista Audubon Society website:

Once on the site’s Birding Resources page, you should be able to easily view
and download the document. Once downloaded, it should be SEARCHABLE, for ease
of finding particular species, observer names, locations, or whatever.
(Alongside the database on this website page there is also an electronic
version of the San Diego County Bird Atlas.)

I plan to continuously update this database, and to post updated versions
approximately every six months. If anyone is interested in the most current
version at any time between those intervals, feel free to contact me privately.

And please do let me know about any errors or omissions you might find. No
correction is too minor!
