Bowerbirds

Bowerbirds 神奇之處是他們是天才建築師, 為了吸引女性, 他們會建一巢(請看圖), 外面加很多裝飾品(有石塊/水果/果實/花葉/汽水罐... 所有有顏色的東西), 而顏色的挑選完全是由男性認為什麼顏色可以吸引自己喜愛的女性, 而已這些個人口味完全是從遺傳因子而來的.

在影片開頭,  Chris 介紹了他要去睇 Nitrates Mine, 在19世紀Nitrates又叫white gold, 非常值錢是用來製造 gun powder 的 guano (海鳥屎含豐富的硝酸鹽).

guano:  The word "guano" originates from the Andean indigenous language Quechua, which refers to any form of dung used as an agricultural fertilizer.
