It is hard to guess what a Hoary bat weights. But we have the answer:
An adult Hoary bat (Lasiurus cinereus) on average weights 27 grams (0.06 lbs).
The Hoary bat is from the family Vespertilionidae (genus: Lasiurus). It is usually born with about 5 grams (0.01 lbs). They can live for up to 2.08 years. When reaching adult age, they grow up to 7.5 cm (0′ 3″). On average, Hoary bats can have babies 1 times per year with a litter size of 2.
As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.
The hoary bat (Aeorestes cinereus) is a species of bat in the vesper bat family, Vespertilionidae. It lives throughout most of North America and much of South America, with disjunct populations in the Galápagos Islands and Hawaii.
