Figure 7.3: 後腿相當粗勇,這算是hare的特徵。

Jackrabbit算是常見的野兔,不過這是我有印象裡第一次看到這兔子的地方。雖然這兔子的名稱有rabbit這字,但jackrabbit實際上屬於hare而不是rabbit,而hare與rabbit的異同也算是FAQ。

視覺上後腿是一個很大的不同之處,hare的後腿比前腿粗勇,但rabbit的四條腿比較平均。此外,如果你同時看到好幾隻,那是rabbit;如果只看到一隻,那可能是hare,因為rabbit是social animal但hare是獨行俠。

Jackrabbit也可以在沙漠看到,比如我就曾在Joshua Tree National Park與Anza-Borrego Desert State Park也看過。
