Résumé :	Sightings data collated from the European Atlantic coastline reveal a recent change in the post-breeding distribution of the Balearic Shearwater Puffinus mauretanicus, and provide evidence for a progressive northwards shift in dispersal patterns. Numbers recorded in the traditional post-breeding quarters, centred on the French Biscay coast, have declined since the mid 1990s and now show marked inter-annual variability. In contrast, numbers recorded from northwest European coastlines have increased since the mid 1990s, the majority being seen along the coasts of northern France and southwest Britain, with smaller numbers north to southern Scandinavia. Although variability in observer effort may have contributed to the observed increase in northwest Europe, the spatial and temporal consistency of the data suggests that the trend is real. Large numbers of this Critically Endangered seabird are now spending part of the year in British and Irish waters; this paper highlights the need for future effort-based surveys across the species non-breeding range, and will provide a baseline for conservation measures in northwest European coastal regions, where large concentrations now occur regularly.
