Linking at-sea mortality of a pelagic shearwater to breeding colonies of origin using biogeochemical markers

We analysed feathers from flesh-footed shearwater collected from 5 breeding colonies throughout their range. Using stable isotopes and trace element concentrations, we assigned birds recovered from fishing vessels to colony of origin, and investigated the rate of correct assignment at 3 spatial scales.

Re-examining mortality sources and population trends in a declining seabird: using Bayesian methods to incorporate existing information and new data

We used Bayesian statistical methods to combine data from the literature with more recent, but incomplete, field data to estimate population parameters and trends. There is a 70% probability that the flesh-footed shearwater population on Lord Howe continued to decline during 2003–2009, and a number of possible reasons for this are suggested.
