Observational mark-recapture study reveals seasonal migration and reproductive timing in little brown bats, highlighting regional ecological connectivity and wintering cave fidelity.

Key Points

To characterize the seasonal migration routes, reproductive timing, and population biology of the little brown bat (Myotis lucifugus) across hibernacula and summer roosts.
Banded over 73,000 bats (approximately 49,000 in caves and abandoned mines, and 24,000 across 193 summer maternity colonies in buildings) between 1960 and 1963.
Conducted 55 longitudinal population surveys at Aeolus Cave in southwestern Vermont and monitored two abandoned iron mines in Essex County, New York, alongside reproductive tissue sampling.
Females emerged from hibernation between early April and mid-May, migrating up to 172 miles predominantly southeastward, whereas males emerged later between 7 May and 7 June.
Maternity colonies formed as early as 22 April, with parturition occurring from 7 June to 10 July; older bats gave birth earlier than yearlings, and offspring achieved flight by mid-July.
Winter hibernaculum population at Aeolus Cave was estimated at 300,000 ± 30,000 bats, serving an estimated summer density of 26 bats per square mile over approximately 8,600 square miles.
