Hare, English hare, German Hase is a common Germanic word *hazán- from an Indoeuropean root *kaz- ‘gray’. This is a fälthare, Lepus europaeus, a (common) European hare, easily seen on the snow. (The hare that turns white in winter is skogshare, Lepus timidus, alpine (mountain) hare).
This is a smart hare, he lives in a nice bush in a small park below my balcony in town. No dogs off the leash or men with guns here.
