Some birds often do incredible things, such as practicing aerobatics; look at whales, when one has been beached in a certain place, six months later another will get stranded there; owls live in trees and every year they will return to the same tree to nest.
有些鳥經常會做些不可思議的動作，譬如練習盤旋；或者像鯨魚，有一隻上岸，半年後又有一隻在同樣地方上岸；貓頭鷹住在樹上，每年回來還是會在同一棵樹上築巢，這些動物行為可能還沒到思考階段。
