Field Fun Friday

What do -38°C, a spacesuit and a wooden post have to do with songbird research?
I could only hold the camera for a couple seconds before my fingers froze. My field partner, Logan, and I had just snowmobiled a half an hour from our truck parked on an ice road ~80 km south of the Nunavut border, in the tundra of the NWT. We were not actually wearing spacesuits, but our big onesies, snowmobile helmets and steel-toed winter boots made it look like we were. Our task was to collect acoustic recording units (ARUs) deployed by Environment & Climate Change Canada (ECCC). The ARUs were deployed last year when the ice road was open, but started recording in the spring, after birds had arrived. Winter is the only time this northern boreal/tundra transition area is accessible. 100 ARUs, mounted on trees and wooden posts (when there are no trees), span a 400 km south-north transect along the ice road. After retrieval, recordings will be analyzed to identify bird species. This marks the start of a long-term monitoring project to identify and track the northern limits of songbird ranges, a topic of great importance in the face of a changing climate. Students from Dr. Erin Bayne’s lab collaborate with ECCC on songbird research using ARUs.
