Trace metal distribution in feathers from migratory, pelagic birds using high-resolution synchrotron X-ray fluorescence microscopy

We used the X-ray fluorescent microprobe at the Australian Synchrotron to obtain high resolution elemental images of breast feathers collected from chicks of Flesh-footed Shearwater. The study revealed previously unknown distribution patterns of trace metals, including those arising from major pollutants such as micro-plastics.

Trace element concentrations in feathers of Flesh-footed Shearwaters (Puffinus carneipes) feathers from across their breeding range

We sampled Flesh-footed Shearwater feathers from New Zealand, Lord Howe Island, and Western Australia during the 2008 austral summer and found colony differences in all elements except lead and thallium. We conclude that mercury, and potentially arsenic and cadmium, represent toxicological concerns for this declining species

Double white lines on the bill of the Razorbill (Alca torda): remnants of an association with the extinct Great Auk?

Here we report the presence of two white bill lines in 10 wintering Razorbills from Newfoundland, Canada in addition to a small number of unreported birds from museum collections. Multiple white bill lines were a characteristic of the Great Auk and we speculate that this variation in the bill marking in the Razorbill is an atavism, reflecting their common ancestry
