The Powers lab collected data on hummingbirds for nearly a month at the Southwestern Research Station (SWRS) from the latter part of May to late June. Collectively we gathered data on nighttime body temperature management, daytime body mass management, and evaporative heat dissipation during hovering. Collaborator Anusha Shankar (Stony Brook University) and Sarah arrived two weeks before the rest of us to finish up measurements showing use of shallow torpor by hummingbirds. Once Don and Natalie arrived measurements of daytime body mass management and evaporative heat dissipation began. While the evaporation measurements were less successful than we hoped, we still ended our time at SWRS with tons of good data.
