One ring does not fit all: Evaluation of banding‐related injuries in tricolored bats

Abstract The potential harm inflicted by forearm bands on bats has been debated for decades. To aid in decision‐making regarding bat marking, we conducted a comprehensive assessment of banding injuries using recapture data from a long‐term overwintering study in Georgia, USA, involving 776 banded tricolored bats ( Perimyotis subflavus ) with 284 recaptures. Most recaptured bats showed no visible injuries (77.8%); however, 22.2% of bats presented varying degrees of band‐related injuries. Although <25% of tricolored bats exhibited banding‐related injuries, sublethal effects of injuries are unknown and could add additional stressors to bat populations already facing multiple threats, including mortality from white‐nose syndrome. Thus, we recommend that banding bats, especially species that have experienced white‐nose syndrome‐related population declines, be appropriately justified and their use carefully considered. Our study contributes valuable knowledge to aid in informed decision‐making on the use of capture‐mark‐recapture methods in the research and management of bat communities.
