Abstract

After accounting for body size, bats have the longest lifespan of all mammals. Little Brown Bats (Myotis lucifugus) are one of the most common and widely distributed mammals in Canada; however, little is known of their longevity. We captured bats in Cypress Hills Interprovincial Park, Saskatchewan in May 2015, as part of long-term bat research in the Park that began in 1991. On 31 May 2015, we captured 16 female Little Brown Bats in a maternity colony, including a bat that was originally captured and banded as an adult in 1993. This capture record indicates that the female bat was at least 23 y old and this record represents the oldest bat record in Saskatchewan. Little Brown Bats in eastern North America have declined dramatically due to white-nose syndrome, a fungal disease responsible for the quickest wildlife die-off in history. Pre-infection natural history data for Little Brown Bats are important as the disease spreads through central Canada.
