Expanded dataset of measurements to be used in evaluating consequences for flight control and stability induced by attachment of bio-logging devices to birds and bats

Bio-logging is central to study of wildlife, but questions remain about minimization of effects from bio-logging devices. Rarely considered are changes bio-logging devices induce on an animal’s center of mass (COM) and resulting losses of flight control and stability. In a related paper (Katzner and Young 2024), we applied established aeronautical principles to estimate how the COM of a flying bird or bat may be affected by typical positioning of a bio-logging device on the neck, back, hips, or tail. We then adopted modified thresholds from aerospace engineering to estimate limits beyond which changes to COM result in fitness-relevant alterations to flight control and stability. Here we provide measurements for other species, beyond the seven reported in Katzner and Young (2024).
