We sampled blood and moulted feathers of the Little Penguin from three distinct colonies subject to varying levels of anthropogenic impact. Non-essential trace metal concentrations were clearly linked to the level of industrialisation adjacent to the respective foraging zones.
We compiled records of Flesh-footed Shearwaters off the Pacific coast of Canada and Alaska from 1937 to 2013. Flocks of more than 20 birds have not been recorded since the 1940s, and most sightings have been of single birds.
We analysed trace element concentrations from breast muscle of 51 auks collected off Newfoundland in the 2011–2012 hunting season. Fourteen (27%) exceeded Health Canada or international guidelines for arsenic, lead, or cadmium; none exceeded guidelines for mercury
Results of a survey of 20 Flesh-footed Shearwater breeding islands in South and Western Australia during 2011–2014, and a synthesis of all available data indicate the current global population is substantially smaller than previously thought, comprising no more than 74 000 breeding pairs
