ABSTRACT: The California Bird Records Committee reached decisions on 285 
records involving 92 species evaluated during 2007, endorsing 238 of them. New 
to California were Townsend’s (Newell’s) Shearwater ( Puffinus auricularis neiuelli), 
Tristram’s Storm-Petrel (Oceanodroma tristrami), Lesser Prigatebird ( Fregata ariel), 
Swallow-tailed Kite ( Elanoides forficatus), Eurasian Kestrel ( Falco tirmunculus), 
Wood Sandpiper ( Tringa glareola), and Common Rosefinch ( Carpodacus erythri- 
nus). Adusting for these changes brings California’s bird list to 640 species, ten of 
which are non-native. 
This 33 rd report of the California Bird Records Committee (hereafter the 
CBRC or the committee) is the second annual report to be published after 
the publication of Rare Birds of California (CBRC 2007). That book sum- 
marizes the status of all vagrants and rare migrants in the state and details 
all of the committee’s decisions from its inception in 1970 through 2003. 
In it, Appendix H covers selected but not all records from 2004 to 2006; 
therefore, the simple addition of records in this report to those already listed 
in the book could result in incorrect record tallies because some records 
were covered in Appendix H while others were not. This report discusses 
the evaluation of 285 records of 92 species. Although most records pertain 
to birds found in 2007, the years covered by this report extend from 1915 
through 2007. Of the 285 records submitted, the committee accepted 238, 
involving 268 individuals of 83 species, for an acceptance rate of 84%. 
Forty-five records of 25 species were not accepted because of insufficient 
documentation or because descriptions were inconsistent with known iden- 
tification criteria. Two additional records of two species were not accepted 
because of questions concerning the birds’ natural occurrence. Counties 
best represented by accepted records were San Diego (46 records), Imperial 
(26), Monterey (23), Los Angeles (16), Humboldt (13), Santa Barbara (11), 
San Francisco (10, all from Southeast Farallon I.), Orange (9), Ventura (9),
