Don Edwards San Francisco Bay National Wildlife Refuge (6)
[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]
6. Great Blue Heron
Figure 6.1: 差不多是夕陽時候的great blue heron。
Figure 6.2: 只用一隻腳站著。
Figure 6.3: 這兩隻可說是not seeing eye to eye。
Great blue heron算是很常見的鳥,在美國從東岸到西岸、由南到北都看得到,而且未必得在National Wildlife Refuge這類地方才看得到,很多時候開車在農田間的小路上就都看到了,我甚至也在Yellowstone與Grand Teton這兩個國家公園裡都看過這鳥。
這鳥體形跟great egret與sandhill crane很接近,至少算中大型的鳥。這三種鳥應該很難分錯,great egret全身白可說是最好認,而great blue heron有藍有灰,跟sandhill crane全身灰應該也很好區別。
我大部分看到great blue heron的地方屬於淡水,不過這個National Wildlife Refuge屬於鹹水就是。
