Extreme endurance flights by landbirds crossing the Pacific Ocean : Ecological corridor rather than barrier?
Robert E. Gill,T. Lee Tibbitts,David C. Douglas,Colleen M. Handel,Daniel M. Mulcahy,Jon Gottschalck,Nils Warnock,Brian J. McCaffery,Philip F. Battley,Theunis Piersma +9 more
TL;DR: It is proposed that this transoceanic route of bar-tailed godwits may function as an ecological corridor rather than a barrier, providing a wind-assisted passage relatively free of pathogens and predators.
Journal ArticleDOI
Guts Don't Fly: Small Digestive Organs in Obese Bar-Tailed Godwits
Theunis Piersma,Robert E. Gill +1 more
TL;DR: Compared with northbound godwits from New Zealand, the Alaskan birds had very small gizzards, livers, kidneys, and guts, which suggests that upon departure, long-distance migrants dispense with parts of their "metabolic machinery" that are not directly necessary during flight and rebuild these organs upon arrival at the migratory destination.
Journal ArticleDOI
Contrasting extreme long-distance migration patterns in bar-tailed godwits Limosa lapponica
Phil F. Battley,Nils Warnock,T. Lee Tibbitts,Robert E. Gill,Theunis Piersma,Chris J. Hassell,David C. Douglas,Daniel M. Mulcahy,Brett D. Gartrell,Rob Schuckard,David S. Melville,Adrian C. Riegen +11 more
TL;DR: Two subspecies of bar-tailed godwit Limosa lapponica travelling between non-breeding grounds in New Zealand and northwest Australia and breeding grounds in Alaska and eastern Russia are compared, and baueri makes the longest (southbound) and second-longest non-stop migratory flights documented for any bird.
Journal ArticleDOI
Prevalence of Influenza A viruses in wild migratory birds in Alaska: Patterns of variation in detection at a crossroads of intercontinental flyways
Hon S. Ip,Paul L. Flint,J. Christian Franson,Robert J. Dusek,Dirk V. Derksen,Robert E. Gill,Craig R. Ely,John M. Pearce,Richard B. Lanctot,Steven M. Matsuoka,David B. Irons,Julian B.

TL;DR: To investigate the possibility of migratory birds as a means of H5N1 dispersal into North America, birds sampled in Alaska between May 2006 and March 2007 were monitored for the virus in a surveillance program based on the risk that wild birds may carry the virus from Asia.
Journal ArticleDOI
Crossing the ultimate ecological barrier: evidence for an 11 000-km-long nonstop flight from alaska to new zealand and eastern australia by bar-tailed godwits
TL;DR: This paper explored six lines of evidence to answer these questions and found that the distribution of marked birds of the baueri and menzbieri races was significantly different between northward and southward flights with virtually no marked birds resighted along the Asian...
