Sibley duo edition California birds omissions - few and far between
- Steve Sosensky inquired as to which CBRC-recognized species might have been
omitted from the new "Sibley Field Guide to Birds of Western North America,"
as well as which of those might be in the Eastern volume. I did a quick
survey, and found that approximately 28 species out of the 619 on the CBRC
official list are not found in the Western volume, which otherwise covers 703
species. I got the impression that essentially all of the 28 were:
<< * - California Bird Records Committee Review Species (170 species)>> i.e.,
VERY uncommon <<In general, review species average four or fewer occurrences
per year in California, and have been recorded fewer than 100 times.>>
Examples included the Least Grebe and the Brown Shrike. I would imagine that
there might be birders for whom the Sibley Western might not suffice, but
surely for the 449 non-review species, and for the more than 80% of the
"review species" that are included, a total of about 590, it should.
What I did not do was to see how many of the 28 omitted species might have
been in the Eastern volume. Presuming they are there, then for anyone
birding mainly by car, keeping the second volume tucked away for the
unexpected rarity might be prudent, along with other reference items, along
the lines of, say, Don Roberson's excellent "Monterey Birds," for someone
exploring that county (whose author has recorded, I understand, 450 species
(I have cc'd Mr. Sibley out of courtesy, respect, and his possible interest.
He will, bythe way, be speaking in Fallon, Nevada, sometime next month.) And
with that diversion, having seen my first Western Kingbird only yesterday,
I'm off for some lighter reading, a book received in the same shipment as the
Sibley: Kenn Kaufmann's "Kingbird Highway"!!
