Hawaiian Hoary Bat

Hawaiian Hoary Bat

The Hawaiian hoary bat is the only terrestrial mammal native to the state of Hawaii, and it is also known as ʻōpeʻapeʻa which means “half-leaf”. This species is characterized by reddish-brown fur with silvery tints and is almost identical in appearance to the hoary bat found in North America. The Hawaiian hoary bat is smaller bodied compared to its mainland North American counterpart, ranging between 14 – 18 grams. Hawaiian hoary bats typically roost in the leaves of trees, and they migrate seasonally by elevation. They can forage for a wide variety of prey types, but primarily feed on moths. This subspecies is listed as endangered under the Endangered Species Act.
