Don Edwards San Francisco Bay National Wildlife Refuge (7)
[1. 簡介] [2. American White Pelican] [3. California Brown Pelican] [4. Snowy Egret] [5. Golden Eagle] [6. Great Blue Heron] [7. Black-Tailed Jackrabbit] [8. Others]
7. Black-Tailed Jackrabbit
Figure 7.1: Jackrabbit的大耳朵是一個主要特徵。
Figure 7.2: 用後腳搔癢。
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。
