It’s always fun to talk about bats in October. Here at HPPA, where we love bats, we like to call them “sky puppies”!
Our six partner national park sites in Hawaiʻi are all places where you can try to catch a glimpse of the cute little fuzzball known as the Hawaiian hoary bat. “Hoary” means frosted, like “hoarfrost”, and here it describes a mature bat whose deep, glossy, brown fur is tipped with white. These bats can also have a tan collar and ears, with fancy black ear tips. Their Hawaiian name is ʻōpeʻapeʻa (oh pay uh pay uh) and they are pretty small—only 24 grams when fully grown. That is about the same weight as a AA battery. Their little wingspans max out at just about a foot wide. Small bats like this are called “microbats”.
Because of the difficulty of reaching these remote islands for just about any animal, the ʻōpeʻapeʻa is the only native land mammal in Hawaiʻi, and listed as an endangered species. Most scientists say that it is closely related to the North American hoary bat, and arrived in the islands a ~10,000 years ago, probably pulled along by the winds of a huge storm or series of storms.
