33RD REPORT OF THE CBRC: 2007 RECORDS 
SANDWICH TERN Thalasseus sandvicensis (4, 1). One at North I. Naval Air 
Station, SD, 4 Aug 2007 (DP; MSt; 2007-157) went two rounds before unanimous 
acceptance. Several members commented on the small amount of orangish coloration 
along the tomium, suggesting it might derive from hybridization or introgression, most 
likely with the Elegant Tern (T elegans). 
THICK-BILLED MURRE Uria lomuia (47, 1). One flying past Pt. Pinos, MTY, 11 
Dec 2006 (BLS; 2007-272) was seen briefly but was well described and sketched. 
IDENTIFICATION NOT ESTABLISHED: One ~3 miles north of Bodega Bay, SON, 
9 Jun 2007 (2007-140) met with resistance, even though most members agreed the 
identification was probably correct, because the bird’s bill shape and structure were 
not described and the outlier June date warranted more thorough documentation. 
PARAKEET AUKLET Aethia psittacula (79, 8). Seven were found feeding along 
a break in a current -38-40 n. miles WSW of San Nicolas I., VEN, 21 Apr 2007 
(OJ; TABt, DMC, MSanM, GTf; 2007-108; photo in N. Am. Birds 61:511). One 
found alive on Venice Beach, LA, 18 Jun 2007 perished in captivity the next day 
(KLGt; LACM #114551; 2007-127). 
IDENTIFICATION NOT ESTABLISHED: One off the Big Sur R. mouth, MTY, 2 
Jun 2007 (2007-149) was too distant for the bill shape or color to be seen in the 
field, though the described plumage pattern of gray above and white below sug- 
gested this species. Most members thought the bird was too distant to be identified 
conclusively. 
*RUDDY GROUND-DOVE Columbina talpacoti (109, 1). An old record by a 
very experienced observer of one at Pt. Loma, SD, 14 Oct 1990 (REW; 2007-181) 
was accepted unanimously. The committee reviews Ruddy Ground-Dove records 
through 2003. 
SNOWY OWL Bubo scandiacus (60, 1). A second-year male was at the south 
spit of Humboldt Bay, HUM, 26 Mar-1 Apr 2007 (SCf, GSLf, RLVt, SMcf, KRf; 
2007-088; photo in N. Am. Birds 61:507). It established the latest date for this 
species in California. 
GREEN VIOLETEAR Colibri thalassinus (2, 1). One in Berkeley, ALA, 18 Aug 
1977 (DHo, FCH; 1977-159A) was re-reviewed and accepted after two rounds fol- 
lowing acceptance of California’s first record from Mt. Pinos, KER, from the same 
summer (Iliff et al. 2007). Though the record was originally submitted as of a Mag- 
nificent Hummingbird ( Eugenes fulgens ), an analysis by J. V. Remsen steered the 
committee in the right direction, and the record was circulated as one of the Green 
Violetear. This bird spent a day coming to a feeder in the Berkeley hills just one week 
after the last appearance of the bird at Mt. Pinos. Concerns over the identification 
were allayed by the detailed description written by an observer unfamiliar with the 
species. Archiving of records, arguably a bird records committee’s most important 
function, is invaluable in allowing future committees to reconsider historic records as 
new information becomes available. 
BROAD-BILLED HUMMINGBIRD Cynanthus latirostris (72, 1). An adult male 
attended feeders in Atascadero, SLO, 23 Nov-3 Dec 2007 (KJZf; CAMf, BKSt; 
2007- 274; photo in N. Am. Birds 62:153). 
IDENTIFICATION NOT ESTABLISHED: A female hummingbird photographed at 
a feeder in La Jolla, SD, 31 Aug-5 Sep 2007 (2007-175) was an aberrant Anna’s 
Hummingbird with a largely pinkish bill. 
RUBY-THROATED HUMMINGBIRD Archilochus colubris (10, 1). An immature 
male was videotaped attending a feeder in Bolinas, MRN, 27-28 Aug 2007 (KHf; 
2008- 029). 
GREATER PEWEE Contopus pertinax (39, 0). One at Griffith Park, LA, 6-15 Apr 
180
