Above is a graphical presentation of the episode, a more detailed text version of the timeline is below

Selected material
Bats hunting insects and spiders

Bats coping in winter
In Texas they migrate but in Canada they manage differently

Evolution in reverse?
Bats are aerial predators but the uneaten prey is mainly down on the ground. Solution? The bats abandon flying !!

A bat entering the scene WALKING on its WRISTS. Below is another look where a ring emphasises the use of the wrist (44’32 & 45’15).

The bats actually form packs where if an insect might avoid one bat it would end in the mouth of the next one instead. Obvious on the video, but invisible in this medium.
