Watching squirrels

Darting along branches, the squirrel moves with an confidence that seems to laugh at gravity. Not many climbers match it.

That plume of a tail acts as a counterweight, helping the squirrel steady itself in a leap.

In autumn, squirrels bury nuts across their range, hoarding food for the lean months ahead.

Remarkably, a squirrel can relocate many of its hidden stores, aided by a keen memory and sense of smell.

The buried caches often take root, so squirrels unwittingly help plant the next generation of trees.

Ever watchful, a squirrel will dash up a trunk at the first hint of danger.
