【小ネタ】Mad March Hare

不思議の国のアリスで有名な３月ウサギ。

European hare が、３月くらいになると殴る蹴るの大げんかを始めるところからついたようです。
（Hare boxingとか、言うらしい）
繁殖期のはじめに割と見られることから、オス同士のメスを巡る戦いか、と思われますが、さにあらず。

Mad March hare behaviour is not, as many people think, fighting males. In fact it's a battle of the sexes - an unreceptive female showing a male she doesn't want to mate with him.
Actually it's more like kick boxing, because they use their feet as well as their fists. And because she weighs more than the males (3.7kg versus 3.3kg), the males usually quickly throw in the towel.

だ、そうです。

ウサギの世界もいろいろと大変そうです。
