Science fact of the day: Bats roost upside down for a reason

Bats are commonly associated with Halloween, but have you ever wondered why they roost upside down?

Bats do this because the lightweight bones in their hind legs can’t support their bodyweight when in an upright position!

Bats are also adapted to transition from their unique resting position into flight.

In fact, most bats take off by dropping from a hanging position and many species are completely unable to take flight from an upright position on the ground.
