Hi folks,

My but the biologists have been busy (or at least their publishers). =
Just got the March 1996 Volume of the Wilson Bulletin, journal of the =
Wilson Ornithological Society. Here's the articles for those =
interested:

they abandoned their Class IIC or Class III ducklings.

Interspecific variation in the calls of Sphensicus penguins. Nina N =
Thumser, Jeffrey D Karron and Millicent S Ficken. pp 72-79. Study of =
calls suggests Jackass and Magellanic are more similar to each other =
than to Humboldt, and all 3 are distinct from Rockhopper penguin.

Jeffrey Homan, Geo M Linz, Wm J Bleier and Robt B Carlson. pp 104-114. =

than expected frequencies, as opposed to colonies associated with =
pothole and miscellaneous habitats.

Evidence of dual breeding ranges for the Sedge Wren in the Central Great =
Plains. Paul A Bedell. pp 115-122. In central Nebraska, most clutches =
initiated by 2nd week of August. Observers should be aware of potential =
for late-summer breeding in other portions of their range.

Diets of Northern Pygmy-Owls and Northern Saw-whet Owls in West-central =
Montana. Denver W Holt and Leslie A Leroux. pp 123-128. 36% of pygmy owl =
diet was birds; 98% of saw-whet diet was small mammals (voles). =
Indicates the 2 species feed on different prey assemblages.

Effects of egg type on depredation of artificial ground nests. Richard H =
Yahner and Carolyn G Mahan. pp 129-136. Recommend that brown chicken =
eggs be used instead of Japanese Quail eggs (white) when simulating =
nests of Ruffed Grouse or Turkey in artificial ground nest studies.

Food availability and feeding preferences of breeding Fulvous =
Whistling-ducks in Louisiana ricefields. Wm L Hohman, Timothy M Stark =
and Joseph L Moore. pp 137-150. Ducks showed feeding preference for =
aquatic earthworms (Oligochaeta) and wild millet seed (Echinochloa sp). =
Rice made up less than 4% of the diet. Use of ricefields by =
whistling-ducks may benefit farmers if ingestion of weed seeds reduces =
need for herbicide treatments.

Do standardized brood counts accurately measure productivity? John M =
Marzluff and Mary McFadzen. pp 151-153. Study with Prairie Falcon at =
Snake R Birds of Prey Natural Area. Support standardization, but urge =
productivity measurements as late in nesting cycle as possible; 16-50% =
of young attaining 80% of fledging age died before fledging.

Comparative foraging behavior of sympatric Snow Geese, Greater =
White-fronted Geese, and Canada Geese during the non-breeding season. =
Dale E Gawlik and R Douglas Slack. pp 154-159. In rice prairies of =

Luquillo; minor effects of transmitter.

New nesting area of Puerto Rican Parrots. J Michael Meyers. pp 164-166. =
Recent nesting has been almost entirely in old-growth Palo Colorado =
(Cyrilla racemiflora), because of scarcity of nesting cavities in other =
tree species; recruitment of palo colorado is low. Meyers found nesting =
in tabonuco (Dacryodes excelsa) forest.

Neotropical migrants in marginal habitats on a Guatemalan cattle ranch. =
Rodney B Siegel and Marco V Centeno. pp 166-170. Results suggest lands =
already under use for cattle ranching should not simply be written off =
as lost by conservation advocates; riparian corridors and other marginal =
habitat patches can be valuable habitat refuges for a large variety of =
species.

Ungulate ectoparasite removal by Black Caracaras and Pale-winged =
Trumpeters in Amazonian forests. Carlos A Peres. pp 170-175. Ticks and =
tabanid flies may represent a key nutritional supplement to birds.

Notes on the status and behavior of the Swainson's Warbler in Cuba. =
