Mahone Bay Roseate Tern Recovery Project

2008/2009

The lack of tern breeding success on Quaker Island from 2004 to 2007 led BCAF, in consultation with the Canadian Wildlife Service, to refocus their efforts in 2008. It was decided that BCAF would conduct bay wide surveys at a maximum of three times per week. The project focused on documenting tern distribution, abundance, productivity (nest/egg counts), and reproductive success (fledgling counts) throughout Mahone Bay. Primary gull colonies were also surveyed and predator watches were conducted.

In 2008, terns attempted to nest on Crow, Gully, Mason, Pearl, Quaker, and Westhaver Islands. Terns were also observed roosting or foraging near Hobsons, Mash, and Saddle Islands. Of the islands where terns were nesting, terns abandoned Crow, Mason, Pearl and Quaker Islands. The causes for abandonment were avian predation, flooding, and anthropogenic disturbances. Terns successfully nested on Gully and Westhaver Islands and tern fledglings were observed by BCAF staff.
