Under the cover of night a skilled hunter twists and turns in the Hawaiian sky, darting and dodging trees with acrobatic skill to catch dinner.ย� Little is known about this hunter: scientists donโ€™t have an estimate of its population size, and outside of the scientific community, few people even realize that Native Hawaiian bats exist. Mist nets, the kind used to catch and study songbirds, are not very effective when catching bats, as the tiny mammal quickly learns to avoid the net. Temperate North American bats are now threatened by a fungal disease called “white-nose syndrome.” This disease has devastated eastern North American bat populations at hibernation sites since 2007. It follows that the only native land mammal would bear wings. ‘Ōpe‘ape‘a have been reported on all main islands with the largest population residing on Hawai'i. They are solitary creatures and grow to about 6 inches, weigh about an ounce, and have a wing span of only 12 inches. On Hawaiโ€˜i Island, researchers detected โ€˜ลpeโ€˜apeโ€˜a more frequently during the summer at lower elevations, possibly because food is abundant during the summer at lower elevations or because the warmer temperatures mean less stress for newborns and lactating mothers. In 2003 the Hawaiian Hoary Bat Research Cooperative (HHBRC) was formed to prioritize and fund research, members include the Hawai’i Division of Forestry and Wildlife, U.S. It has been seen throughout Maui, from sea level to the top of Haleakala as it swoops through the sky.

Population estimates for the Hawaiian hoary bat have ranged from hundreds (Altonn 1960) to thousands of individuals (Tomich 1974), but these numbers are based on anecdotal and incomplete data. Understanding population boundaries and diet needs, contributes directly to a net recovery for the Hawaiian hoary bat because it managers to balanceallows future threats to island wide bat populations while informing the selection and design ofbat habitats within mitigation reserves. Donald Price (Life Sciences) recently has published two scientific articles describing research conducted in Hawaii. Mother โ€˜ลpeโ€˜apeโ€˜a ย�give birth to pups, typically one set of twins, in May or June and stay with the pups until they are 6-7 weeks old. Recovery Plan for the Hawaiian Hoary Bat – USFWS 1998 SPECIES INFORMATION: The ‘ōpe‘ape‘a, or Hawaiian hoary bat (Family: Vespertilionidae), is Hawaii’s only native terrestrial mammal, although fossil evidence indicates that at least one other bat species was native to the islands.

The ope’ape’a is the official state mammal of Hawaii. Hawaiian hoary bat population estimates have ranged from a few hundred to a few thousand (Mitchell et al. Mar. Population estimates for all islands have ranged from hundreds to a few thousand, however, these estimates are based on limited and incomplete data. Whereas the mainland hoary bat is found throughout North and South America, the Hawaiian hoary bat is distributed only among the major volcanic islands of Hawaiʻi, making it the only extant and native terrestrial mammal in the state. Found only in Hawaiโ€˜i , itโ€™s listed as a federally endangered species. PO Box 983, Makawao, HI 96768, Manager: Adam Radford ‘Ōpe‘ape‘a (Hawaiian hoary bat) is the only native land mammal of Hawai'i.
