1 November 2018The Recent Invasion of Cory's Shearwaters into Atlantic Canada
Calonectris diomedea (Cory's Shearwater) are observed in small numbers in Atlantic Canada every year. However, in 2016 and 2017, unusually high numbers were reported in both Nova Scotia and Newfoundland and Labrador, Canada. We used data from eBird and from standardized ship-based surveys to document the timing and magnitude of the increase. Results show that densities have been increasing in waters off Nova Scotia since 2007 and are now of similar magnitude to those observed on George's Bank in the late 1980s, which suggests that birds are targeting cooler, more productive waters on the Scotian Shelf during migration. Continued monitoring using a variety of survey techniques will help identify important marine areas for this trans-equatorial migrant, and identify potential threats as birds move into areas not previously explo ited.
