Hi folks,

Just got the Spring 1996 issue, Volume 67, No 2, of the Journal of Field =
Ornithology, published by the Association of Field Ornithologists. Hope =
some people get some use from these contents.

Movements of Double-crested Cormorants Among Winter Roosts in the Delta =
Region of Mississippi. D Tommy King. pp 205-211. Studied movements from =
roosts, near catfish farm ponds, dispersed by pyrotechnics. As with =
other communal roosting birds, cormorants that winter in Mississippi =
seem to show no strong fidelity to a primary roost.

Removal of Old Nest Material From the Nesting Sites of House Wrens: =
Effects on Nest Site Attractiveness and Ectoparasite Loads. L Scott =
Meadows. pp 212-221. Wrens in Wyoming showed no preference for nest =
boxes with or without old nesting material, unless material was soiled. =
No difference in reproductive output. Young in nests with old material =
did not have higher loads of blow fly larvae (blow flys do not =
overwinter in nests).

Eastern Meadowlarks Nesting in Rangelands and Conservation Reserve =
Program Fields in Kansas. Diane A Granfors, Kevin E Church and Loren M =
Smith. pp 222-235. No significant difference between cover types but =
power of tests was low. Mowing CRP fields was source of nest failure =
and abandonment; predation was primary cause of nest failure. Delay in =
mowing/burning was recommended.

Sexual Size Dimorphism in Birds from Southern Veracruz, Mexico. II. =
Thryothorus maculipectus and Heniocorhina (Leucosticta) prostheleuca. =
Kevin Winker, John T Klinka and Gary Voelker. pp 236-251. Sexually =
monochromatic tropical wrens.

Juvenile Gray Jay Preys upon Magnolia Warbler. William H Barnard. pp =
252-253. In Vermont.

Changes in the Winter Abundance of Sharp-shinned Hawks in New England. =
Charles D Duncan. pp 254-262. Fewer sharp-shins migrated past Cape May, =
NJ; CBC data suggest sharpies wintering in New England have increased by =
more than 500%!

Capture Efficiency of Mist Nets with Comments on their Role in the =
Assessment of Passerine Habitat Use. Lukas Jenni, Markus Leuenberger and =
Filippo Rampazzi. pp 263-274. Capture frequencies from mist-netting =
are adequate for assessing habitat use of small birds; capture numbers =
do not represent quantitatively the species composition; many variables =
in efficiency.

Nest Visitation by Humans does not Increase Predation on =
Chestnut-collared Longspur Eggs and Young. Danielle R O'Grady, Dorothy P =
Hill and Robert MR Barclay. pp 275-280. At Remount Community Pasture, =
Bindloss, Alberta.

Methods used to Improve Least Tern and Snowy Plover Nesting Success on =
Alkaline Flats. Marcus T Koenen, Russell B Utych and David M Leslie Jr. =
pp 281-291. Nest ridges did not reduce loss to flooding, and =
solar-powered electric fences did not reduce annual egg predation by =
coyotes at Salt Plains NWR, Oklahoma.

Foraging Ecology of Pale-faced Sheathbills in Colonies of Southern =
Elephant Seals at King George Island, Antarctica. Marco Favero. pp =
292-299. Afterbirths and pup carcasses constituted the bulk of food =
consumed.

Nest Sites of Kentucky Warblers in Bottomland Hardwoods of South =
Carolina. John C Kilgo, Robert A Sargent, Karl V Miller and Brian R =
Chapman. pp 300-306. Nests were on the ground, supported by the bases =
of herbs and woody seedlings; nest patches were situated in tree-fall =
gaps.

Long-distance Movements by American Avocets and Black-necked Stilts. =
Julie A Robinson and Lewis W Oring. pp 307-320. Birds left Honey Lake =
Valley (NE Calif), to stopover areas at Mono Lake and the Tulare Basin. =
Wintered along Calif Coast south of Arcata and also on coast of Sinaloa. =


Delayed Nesting Decreases Reproductive Success in Northern Flickers: =
Implications for Competition with European Starlings. Danny J Insgold. =
pp 321-326. At least 58% of flicker pairs in Ohio that delayed clutch =
completion until after June 1st were forced to delay by starlings; =
reduction in flicker fecundity attributed to competition with starlings.

Migration and Dispersal in Great Lakes Ring-billed and Herring Gulls. =
Steven W Gabrey. pp 327-339. Most Great Lakes Ring-billed gulls wintered =
along Gulf Coast, especially in Florida; most Herring Gulls wintered =
along Lake Erie.


Under "News and Notes", Tweeters and Oregon Birders On-Line folks might =
want to be reminded that the American Ornithologists' Union is holding a =
joint meeting in Boise, Idaho from 13-17 August at Boise State =
University.

And, finally, I have to quote a review by Jerome A Jackson under "Recent =
Literature":

"29. Penguins bled by vampires. G. Luna-Jorquera and B.M. Culik. J. =
Ornithol. 136:471-472. - The authors found a vampire bat (Desmodus =
rotundus) apparently attempting to feed on the blood of a Humboldt =
Penguin (Sphensicus humboldti) chick on Isla Pan de Azucar, Chile. While =
there were two chicks present, only one was "attacked" - so the title =
here is a bit misleading. The bat was seen leaving the chick which was =
found to have "two small cuts" on the tarsometatarsus. This is merely a =
first record of a vampire bat attempting (?) to feed on bird blood. The =
authors present no evidence that vampire bats regularly attack penguin =
chicks, ever attack adult penguins, or that they cause serious harm to =
the penguins. They do mention the potential of disease transmission. An =
interesting anecdote, but much more evidence is needed. Rabid penguins? =
(Institut fur Meereskunde, Dusternbrooker Weg 20, D-24105 Kiel, =
Germany.)
