Hares

Hares and jackrabbits are leporidaes belonging to the genus Lepus. (There are four other species called hares: Caprolagus or the Hispid Hare, and Pronolagus or the red rock hares.) Hares less than one year old are called leverets.

Hares are very fast-moving. The Europeon-Brown Hare (Lepus europaeus) can run at speeds of up to 72 km/h (45 mph). They live solitarily or in pairs, while a "drove" is the collective noun for a group of hares. Their bodies are capable of absorbing the g-force produced while running at extreme speeds or while escaping predators.

A common type of hare in Arctic North America is the Snowshoe Hare, replaced further south by the Black-tailed Jackrabbit, White-tailed Jackrabbit and other species.

Normally a shy animal, the European Brown Hare changes its behaviour in spring, when hares can be seen in broad daylight chasing one another around meadows; this appears to be competition between males to attain dominance (and hence more access to breeding females). During this spring frenzy, hares can be seen "boxing"; one hare striking another with its paws (probably the origin of the term "mad as a March here"). For a long time it had been thought that this was inter-male competition, but closer observation has revealed that it is usually a female hitting a male, either to show that she is not yet quite ready to mate, or as a test of his determination.
