was of an adult, the first adult recorded in fall in California since the committee began 
reviewing records of this species in 2004 and explaining the early date (J. L. Dunn 
pers. comm.). 
IDENTIFICATION NOT ESTABLISHED: Six records involving seven birds were not 
accepted because the committee concluded that the Pacific Golden-Plover (P. fulva) 
was not eliminated: one at the wastewater-treatment facility at Naval Air Weapons 
Station, China L., KER, 20-21 May 2006 (2006-070), two there on 28 Apr 2007

I., VEN, 10 Mar 2007 (RHt; 2007-073). One at La Jolla, SD, 2-17 Dec 2007 
(BDot; 2007-291) was considered a returning bird (2006-117; see Heindel and 
Garrett 2008). 
IDENTIFICATION NOT ESTABLISHED: The description of an oystercatcher at 
Royal Palms Beach and Cabrillo Beach in San Pedro, LA, 4-16 May 2006 (2006-073)
