Indeed, records of Common Shelduck from Newfoundland continue to accrue (17 November 2009; 2 April 2014), and a subadult noted 18 No- vember 2013 at Barbados, an island from which numerous Old World species have been recorded, broadens the pattern further and strengthens the case for the species as a constituent of the New World avifaunal list. Certainly, all Common Shelducks observed in the wild should be studied carefully and photographed. If specimens or feathers are obtained, deuterium isotope analysis could help establish the provenance of a shelduck as a legitimate vagrant. Literature cited Brinkley, E. S. 2010.
