Hurricane Lee is making its way toward Nova Scotia, with landfall predicted on Saturday midday. Although this may not be the strong storm it once was, it will still pack a dangerous punch of wind, storm surge, and rain in the Canadian Maritimes. With safety first above all, BirdCast is posting a map of observations for entrained and displaced birds associated with the passage of this storm. Birders that can safely observe should watch for an array of seabirds, that may include, based on previous storms like Teddy, Pterodroma petrels (Bermuda, Trinidad, Black-capped and Fea’s), Audubon’s Shearwater, White-faced, Band-rumped, Leach’s and Wilson’s Storm-Petrels, Magnificent Frigatebird, White-tailed Tropicbird, Sooty, Bridled, and Least Terns, Sabine’s Gull, Long-tailed Jaeger and others.

Will Lee bring any more typically coastal species, like Royal and Sandwich Terns and Black Skimmer, or has it been offshore too long to entrain and to displace such things? Further regarding displacement, will the storm, with its strong circulation of northeasterly winds on Canada’s Atlantic coast deposit large numbers of non-tropical, local near shore species (jaegers, phalaropes, tubenoses)? An intriguing questions about entrained, tropical species, if present: will there be more Bridled Terns that Sooty Terns in this system, given the prevalence of Sargassum this season and the track of the storm through the heart of its distribution?
