Walking nearby Taipei 101, I guess I may have heard the call of the Grey treepie before I looked up at the tree. Its calls must be very special and loud, otherwise I won’t notice it in the noisy street. The grey treepie is largely arboreal. They spend most of their life in trees. They are omnivorous birds.
走在台北101附近，我猜我可能是聽到灰樹鵲的叫聲才抬頭往樹上看，牠的叫聲一定很特別也大聲，否則在嘈雜的街上，怎麼會注意到牠。灰樹鵲主要是樹棲的，一生大部分的時間都在樹上活動。牠是雜食性鳥類。
