Nighthawk Migration & Wintering Areas



A new cooperative research project conducted by representatives of several organizations helped to attach new miniature GPS-satellite tags on 52 Common Nighthawks at 13 locations across the species’ expansive nesting range to better understand where these birds spend their time throughout the year. The study provided insights about their ecology, especially during winter and migration periods. Common Nighthawks are one of the Western Hemisphere’s most widespread migratory species, yet we know little about them after they leave their nesting sites.
The study was initiated by the Migratory Connectivity Project at the Smithsonian Migratory Bird Center, and co-led with the department of Environment and Climate Change Canada and the University of Alberta. Their new research publication has just been released this month in the scientific journal Ecography. Recent estimates indicate that Common Nighthawks have declined by more than 50 percent during the past 40 years. Nighthawks are aerial insectivores – birds that catch insects in flight – a group that is declining faster than any other group of birds in Canada. Read more







For Karner blue butterfly populations to thrive, the area must be periodically burned with fire or mowed to remove any large woody species that may cast shade on the lupine. To protect the lupine and over-wintering egg clutches, mowing can only occur when at least 4 inches of snow has accumulated. This winter habitat management activity will produce flourishing native wildflowers and fluttering insects this spring and summer.
