| metabolic profile of long-distance migratory flight and stopover in a shorebird. | migrating birds often complete long non-stop flights during which body energy stores exclusively support energetic demands. the metabolic correlates of such long-distance travel in free-living migrants are as yet poorly studied. bar-tailed godwits, limosa lapponica taymyrensis, undertake a 4500 km flight to their single spring stopover site and thus provide an excellent model in which to determine the energy fuels associated with endurance travel. to this end, we evaluated plasma concentrations ... | 2005 | 15705555 |
| breeding plumage honestly signals likelihood of tapeworm infestation in females of a long-distance migrating shorebird, the bar-tailed godwit. | the indicator mechanism for sexual selection proposed by hamilton and zuk (i.e. that sexually selected ornaments signal parasite resistance) has received rather little observational support, and none in the case of long-distance migrant birds. here we present a test by examining the association between helminth infestations and breeding plumage quality in bar-tailed godwits limosa lapponica taymyrensis during their spring staging period in the wadden sea, the netherlands. after a non-stop flight ... | 2001 | 16351817 |
