3 Cal official bird list questions
- Hi Folks,
1) I have been looking at the list of California birds online at the CBRC web site. Is there a page with more details, say dates and locations for the really rare birds?
2) Is the Gray Silky Flycatcher that's on the list the Orange County bird?
3) No Yellow Grobeak? As far as I understand, Yellow Grosbeak has been seen in California. Of course, it's one of those possbly escaped captive birds, so it's origin may be questioned (questionable), but I would really love to know more details about Yellow Grosbeak sightings in California, and googling hasn't gotten me far...

Some quick answers to your queries about the California state list.
First, a book with exhaustive details on all of the records ever
reviewed by the CBRC as well as detailed species accounts for all
vagrants and scarce migrants in the state is nearing completion. So
many people have worked hard on this book for so long that I hesitate to
even give credit to anybody, but certainly Robb Hamilton, Dick Erickson,
Michael Patten and Paul Lehman should be mentioned, and a couple of
dozen other people were involved with various stages of the production
of the book. Western Field Ornithologists will publish the book; no
publication date has been set, but
watch for announcements beginning this fall.
Until this book is published, your best bet is to look at the regular
reports of the California Bird Records Committee published on a roughly
annual basis in Western Birds. Some of these reports are available on
the WFO-CBRC web site, and all of the content of Western Birds (except
for the most recent 1-2 volumes) should available later this year
on-line through SORA. Of course, a good old subscription to Western
Birds through membership in Western Field Ornithologists is always your
Gray Silky-Flycatcher was added to the "Supplemental List" on the basis
of several records, including the one from the Santa Ana Mountains, ORA.
No record of this species has been accepted, but the species received
sufficient support from the CBRC members to place it on the Supplemental
List. Note that the Supplemental List does not contain specific records,
but rather species placed there on the basis of the whole body of
records for the state (in some cases the "whole body of records" is, of
course, just a single record). In the case of the Gray Silky-Flycatcher
I think it is probably fair to say that the Santa Ana Mtns. record was
plausible enough to tip committee opinion in favor of placement on the
Supplemental List. Species on the Supplemental List are NOT on the
"official" state list.
Finally, no Calfornia record of Yellow Grosbeak has been accepted by the
CBRC. A report from Sacramento, SAC in August 1989 was not accepted on
the basis that correct identification was not established. Other
reports, if any, have not been submitted to the CBRC.

- In addition to the resources mentioned by Kimball, a complete lists of
CBRC records (accepted, rejected, etc.) through Jan 1997 is available
right now on Joe Morlan's site. It will have the date of all the older
records of interest. It is at
As to the "supplemental" list, it is possible that the current CBRC is
approaching the issue differently. When I was Secretary (late 1980s),
even the "supplemental" list was a record-driven list. The Committee was
set up to deal with records, not amorphous concepts. It was possible to
determine, at least at that time, which record(s) warranted placement of
a species on the "supplemental" list. This was most obvious in the case
of Crested Caracara, where the species was placed on the "supplemental"
list back then on the basis of a Mono basin record, and not on the basis
of a variety of other old records, including a fair number of reports in
coastal ports that were thought to be ship-assisted. It had always been
my understanding that Gray Silky-Flycatcher was on the "supplemental"
list solely on the basis of the montane bird in Orange County, and not
any of the more questionably wild coastal plain reports, but it may be
that the current Committee takes a different approach. Yet I would have
answered Thomas's question "is the silky-flycatcher on the supplemental
list because of the Orange County bird" with a firm "yes."
