A hummingbird's flapping energy and its size aren't in one-to-one ratio, research finds

A new, University of Toronto Scarborough study has found that when it comes to fuel efficiency, bigger is better for hummingbirds. The goal of the study was to explore the link between morphological traits, like body mass and wingspan, to metabolic rates -- the rate at which the birds consume energy. The research also explored how well hummingbirds turned food energy into motion, also called mechanochemical efficiency.
