Black Beach—not for the Birds: The Significance of Black Beach, New Brunswick, Canada, as a Feeding and Stopover Site for Migratory Dragonflies

Feeding swarms of dragonflies generally form during prey-accumulation events and can be very large (1000+ individuals), dense, composed of multiple species and both sexes, and persist for hours. In the first published account of such a site from Atlantic Canada, I report the regular, yearly occurren...

Description
Summary:Feeding swarms of dragonflies generally form during prey-accumulation events and can be very large (1000+ individuals), dense, composed of multiple species and both sexes, and persist for hours. In the first published account of such a site from Atlantic Canada, I report the regular, yearly occurrence of large, diverse dragonfly feeding swarms at Black Beach, NB, Canada, in September 2014, 2015, and 2019, and also present the species, sex, and relative ages of specimens collected in swarm surveys. I discuss the significance of Black Beach not only as a feeding site during prey-accumulation events, but also secondarily as a stopover site for migratory species.
