We report 4 occurrences of Lasiurus cinereus (Hoary Bat) on the island of Newfoundland, Canada, based on over 50,000 full-spectrum recordings of echolocation calls made at 94 sites, in Gros Morne National Park, between 2013 and 2019. Our detections of few vocalizations by Hoary Bats over multiple years and locations support prior observations that this species is an infrequent vagrant in western Newfoundland and likely not a summer resident.
