GUIDELINES TO THE USE OF WILD BIRDS IN RESEARCH
The Ornithological Council has asked the Office of the Solicitor of the Department of the Interior to determine if the use of SUA to study wildlife is subject to the AHA, and has filed a petition for rulemaking asking the USFWS to issue permits.
Intraspecific Variation in Commuting Distance of Marbled Murrelets (Brachyramphus marmoratus): Ecological and Energetic Consequences of Nesting Further Inland
Abstract Radio transmitters were deployed on Marbled Murrelets (Brachyramphus marmoratus) at Desolation Sound, British Columbia, Canada, during the 1998 breeding season to assess individual variation…
Cracking a developmental constraint: egg size and bird evolution. In Proceedings of the VII International Meeting of the Society of Avian Paleontology and Evolution, ed. W.E. Boles and T.H. Worthy
The evolution of "unrestricted egg size" may have precipitated subsequent development of the diverse reproductive strategies seen in living birds, and correlations between developmental strategies, egg weight and female body mass are corroborated.
Passerines : flycatchers through vireos
This book discusses bird taxonomy, nomenclature, methods, terms, and Abbreviations, and the environment and changes to Ecoprovinces of British Columbia between 1957 and 1993.
Habitat choice in breeding seabirds: when to cross the information barrier
The information barrier hypothesis is suggested: the presence of nesting birds may furnish cues about local breeding conditions that may deter dispersal to new habitat, even though good breeding sites may be available elsewhere.
A Large Accumulation of Avian Eggs from the Late Cretaceous of Patagonia (Argentina) Reveals a Novel Nesting Strategy in Mesozoic Birds
This accumulation reveals a novel nesting behaviour in Mesozoic Aves that was perhaps shared with the non-avian and phylogenetically more basal troodontid theropods and may represent the product of a single nesting season or a short series of nesting attempts.
A drowned Mesozoic bird breeding colony from the Late Cretaceous of Transylvania
The first fossil evidence for a breeding colony of Mesozoic birds, preserved at the Late Cretaceous Oarda de Jos (Od) site in the Sebeş area of Transylvania, Romania, is reported, which augments the understanding of enantiornithine biology and shows that colonial nesting was not unique to crown birds.
Rhinoceros Auklet (Cerorhinca monocerata) Nestling Diet May Gauge Pacific Sand Lance (Ammodytes hexapterus) Recruitment
The diet of rhinoceros auklet nestlings at three colonies on the British Columbia coast was studied, suggesting a linkage between ocean production, 0+ sand lance abundance, and events on seabird colonies over a broad geographic range.
MIGRATION CHRONOLOGY, LENGTH OF STAY, SEX RATIO, AND WEIGHT OF WESTERN SANDPIPERS, (CALIDRIS MAURI) ON THE SOUTH COAST OF BRITISH COLUMBIA
--In 1978-1980 and 1985-1986, we banded, weighed, and measured 2660 Western Sandpipers (Calidris mauri) at 2 sites in south coastal British Columbia. Adults migrated north between mid-April and…
Flight energetics of the Marbled Murrelet, Brachyramphus marmoratus
It is concluded that the cruising speed of Marbled Murrelets exceeds Vmr, and two behavioural hypotheses are examined: that flight speeds exceed Vmr to minimize predation rate and maximize chick growth rate.
