The Canadian-banded terns were banded as chicks during the summer of 2009 on Country Island, Nova Scotia, by staff from Environment Canada’s Canadian Wildlife Service. Each juvenile tern carried color leg-bands which made them visible among thousands of Roseate and Common terns staging at eight different sites on Cape Cod. Not insignificantly, Country Island where the terns were banded is a Important Bird Area (IBA) in Nova Scotia. In addition most of the color-marked terns were also relocated at one of two highly significant Massachusetts IBAs located on Cape Cod.
The meticulous survey of color-banded terns at these IBA sites is vital to improving our understanding of the nesting, staging behavior, and migratory timing of Roseate Terns, a species classified as Threatened in Canada and Endangered in the northeastern U.S. Such observations also underscore the significance of IBAs in prioritizing habitat significance at the landscape level. Currently the northeastern population of Roseate Terns which is principally located between the south shore of Long Island, New York and Nova Scotia, Canada, contains approximately 3,000 pairs, with Massachusetts supporting the majority of the population. In 2009 the Massachusetts population was comprised of approximately 1,300 pairs.

The Birding Community E-bulletin is being distributed to active and concerned birders, those dedicated to the joys of birding and the protection of birds and their habitats. You can access an archive of past E-bulletins on the website of the National Wildlife Refuge Association (NWRA):
