The Hawaiian hoary bat, also known as ʻōpeʻapeʻa, is a species of bat endemic to the islands of Hawaiʻi. 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. The Hawaiian hoary bat was officially named the state land mammal of Hawaiʻi in 2015. It is a federally listed endangered taxon of the United States. Like many species of bats, Hawaiian hoary bats are brown in color. However they are distinguished by the silver coloration that ‘frosts’ the fur on their back, ears, and neck. They typically weigh between 14 to 18 g, and have a wingspan of about 10.5 to 13.5 inches, with females being larger than males. They are insectivorous, nocturnal, and forage and hunt using echolocation. They are a solitary subspecies and roost individually rather than in colonies. They are found throughout a large range of different habitats - forests, agricultural fields, and areas populated with humans. Due to their elusive and solitary nature, there is very limited knowledge on the ecology or life history of the bat. As of now, population sizes are unknown, which is problematic because this data is necessary for species recovery plans. Currently the Hawaiian hoary bat is listed as endangered under the Endangered Species Act. Regarding conservation, the Hawaiian hoary bat faces a number of possible threats including: habitat loss, collisions with man-made structures such as wind turbines and barbed wire, impact of pesticides on primary food source, predation and competition with invasive species, and roost disturbance and tree cover reduction.
