Townsend’s Big-Eared Bat 50g Proof Silver
Bats are mammals of the order Chiroptera whose forelimbs form webbed wings, making them the only mammals naturally capable of true and sustained flight. By contrast, other mammals said to fly, such as flying squirrels, gliding possums, and colugos, can only glide for short distances. Bats do not flap their entire forelimbs, as birds do, but instead flap their spread-out digits, which are very long and covered with a thin membrane or patagium.
Townsend’s big-eared bat (Corynorhinus townsendii) is a species of vesper bat and is a medium-sized bat with extremely long, flexible ears (hence the name), and small yet noticeable lumps on each side of the snout. Its total length is around 10 cm (4 in.), its tail being around 5 cm (2 in) Its wingspan is about 28 cm (11 in) It weighs around 7–12 g.
This bat’s diet may include small moths, flies, lacewings, dung beetles, sawflies, and other small insects. One report stated the species feeds almost exclusively on Lepidoptera moths. C. townsendii can be found in Canada, Mexico, and United States. This bat is often distributed near rocky areas where caves or abandoned mine tunnels are available. They may also occasionally inhabit old buildings. The average lifespan of a Townsend’s big-eared bat is 16 years.

The reverse side shows a bat in flight, almost flying out of the coin, surrounded by some stylistic representations of the bat in various poses, all enhanced with just a small amount of colour.
The obverse again has a bat in flight, but this time flying across the coin, and set against a very detailed strike of a cave environment, the bats natural home. It’s quite excellent how the same glass wing is used so well in the two images. The year date and coat of arms for Palau are unobtrusively inscribed in the image.
