Don Powers and Natalie Amodei traveled to Missoula, MT for the lab’s annual trip to work with Dr. Bret Tobalske. Over the years this has been a fruitful collaboration resulting in several publications relating to hummingbird physiology and biomechanics. This year we continued efforts to gather measurements of total evaporative heat dissipation in hovering calliope hummingbirds (Selasphorus calliope) before hopefully expanding these measurements to other species in Arizona next month.

Dinner at the Tobalske's!

GoPro and high-speed video ready to go!
