From: Effects of tag mass on the physiology and behaviour of common noctule bats
A Metabolic power, as predicted by the afpt, of an average common noctule bat across a range of flight speeds (green line) in comparison to the same theoretical bat carrying a 3.8 g GPS tag (orange line). B Box plots (25th and 75th percentiles) show measured metabolic power of six common noctule bats flying in a wind tunnel at 8 m/s, either with or without a 3.8 g GPS tag
