Trans-equatorial migration and habitat use by sooty shearwaters Puffinus griseus from the South Atlantic during the nonbreeding season
The distributions of many marine birds, particularly those that are highly pelagic, remain poorly known outside the breeding period. Here we use geolocator-immersion loggers to study trans-equatorial migration, activity patterns and habitat use of sooty shearwaters Puffinus griseus from Kidney Islan...

The distributions of many marine birds, particularly those that are highly pelagic, remain poorly known outside the breeding period. Here we use geolocator-immersion loggers to study trans-equatorial migration, activity patterns and habitat use of sooty shearwaters Puffinus griseus from Kidney Island, Falkland Islands, during the 2008 and 2009 nonbreeding seasons. Between mid March and mid April, adults commenced a ~3 wk, >15 000 km northward migration. Most birds (72%) staged in the northwest Atlantic from late April to early June in deep, warm and relatively productive waters west of the Mid-Atlantic Ridge (~43−55° N, ~32−43° W) in what we speculate is an important moulting area. Primary feathers grown during the moult had average δ15N and δ13C values of 13.4 ± 1.8‰ and −18.9 ± 0.5‰, respectively. Shearwaters moved into shallow, warm continental shelf waters of the eastern Canadian Grand Bank in mid June and resided there for the northern summer.
