A Maternity Roost of Silver-Haired Bats (Lasionycteris noctivagans) in New Brunswick: First Evidence of Parturition in Atlantic Canada

Abstract

A maternity roost for Lasionycteris noctivagans (Silver-haired Bat) discovered in Fredericton, NB, on 30 June 2020 is the first evidence of parturition for the species in Atlantic Canada and the most northern in eastern North America. The colony consisted of 17 non-volant pups and an estimated 8–10 adult females, with parturition estimated as early to mid-June. The roost was located at a height of ∼9 m in a mature Pinus strobus (Eastern White Pine). There is a need to assess the importance of large trees and stands of over-mature forest for bats in the Atlantic region.
