Here is a summary of the contents of vol. 41 no. 1 (2010) of the
quarterly journal Western Birds, published by Western Field
* EGG-TURNING BEHAVIOR AND NEST ATTENTIVENESS OF THE ENDANGERED HAWAIIAN
GOOSE ON KAUAI.
* by WESLEY W. WEATHERS and BRENDA J. ZAUN.
* pp. 2-9.
* A study of the Hawaiian Goose (Nene) employed remote video cameras to
study parental behavior at two nests on Kauai, Hawaii. Even though the
Hawaiian Goose breeds at latitudes lower than most other geese, the
video revealed egg-turning behavior similar to that reported for other
waterfowl and, in particular, the closely related Canada Goose.
* A NEW AND CRYPTIC CALL TYPE OF THE RED CROSSBILL.
* by KENNETH IRWIN.
* pp. 10-25.
* Acoustic, morphometric, and ecological analyses from Humboldt County,
California, reveal a new call type (type 10) of the Red Crossbill
complex. Type 10 Red Crossbills specialize on Sitka spruce cones, a food
resource previously predicted to have a Red Crossbill call type
associated with it. Type 10 Red Crossbills may be differentiated from
other Red Crossbills by flight calls, "chitter" calls, song repertoires,
feeding ecology, and slight differences in average body size and bill
* A REASSESSMENT OF HOMOLOGIES IN THE VOCAL REPERTOIRES OF PHOEBES.
* by D. ARCHIBALD McCALLUM and NATHAN D. PIEPLOW.
* pp. 26-43.
* A study of dawn singing clarifies homologous (primitive, or ancestral)
song elements of three flycatchers in the genus Sayornis. The Say's
Phoebe uses three song elements, whereas the Black and Eastern phoebes
use only two each. A key to establishing these homologies was
spectrographic analysis of the vocalizations of a hybrid Black x Eastern
Phoebe with a song like a Say's Phoebe.
* GROUND-NESTING MARBLED MURRELETS IN JUNEAU, ALASKA.
* by MARY F. WILLSON, KATHERINE M. HOCKER, and ROBERT H. ARMSTRONG.
* pp. 44-48.
* Observations, photographs, and detailed descriptions establish the
occurrence of three ground nests of Marbled Murrelets in forests around
Juneau, Alaska. In the well-forested Juneau area, Marbled Murrelets nest
both in trees (like breeders to the south) and on the ground (like
breeders to the north and west).
* TWO ORIENTAL TURTLE-DOVES (Streptopelia orientalis) REACH CALIFORNIA.
* by JON L. DUNN and KEITH HANSEN.
* pp. 49-54.
* An Oriental Turtle-Dove was reported from Inyo County, California, 29
October 1988, and another was reported from Marin County, California,
9-31 December 2002. Both reports have been accepted by the California
Bird Records Committee, and both are assumed, but not proven, to refer
to the migratory nominate subspecies.
* A LITTLE BUNTING REACHES BAJA CALIFORNIA SUR.
* by KURT A. RADAMAKER and DAVID J. POWELL.
* pp. 55-58.
* A Little Bunting, likely an immature, was found and photographed on
the Vizcaino Peninsula, Baja California Sur, 8 October 2008. The species
is casual during the fall in western Alaska, but this individual was
only the third ever reported in North America south of Alaska, and it
was the first reported in Mexico.
* BOOK REVIEW.
* reviewed by CHRIS BUTLER.
* pp. 59-60.
* Review of "Avian Invasions: The Ecology and Evolution of Exotic Birds"
(2009), by Tim M. Blackburn, Julie L. Lockwood, and Phillip Cassey.
* BOOK REVIEW.
* reviewed by OSCAR JOHNSON.
* pp. 60-61.
* Review of "Birds of the US-Mexico Borderlands: Distribution, Ecology,
and Conservation" (2008), edited by Janet Ruth, Tim Brush, and David
* FEATURED PHOTO--BLACK-CHINNED SPARROW: NOTES ON BREEDING BEHAVIOR AND
NESTING ECOLOGY IN SAN DIEGO COUNTY, CALIFORNIA.
* by LORI HARGROVE.
* pp. 62-67.
* An observational study of the poorly known Black-chinned Sparrow
establishes quantitative data on spring arrival dates, territory
establishment, nest placement, nest construction, nesting dates, clutch
size, egg and nestling survival, behavior and morphology of nestlings
and fledglings, and adult attendance.
