Since the endemic Mikado pheasant was first recorded 80 years ago, no other new bird species has been discovered in Taiwan, and in recent years although mammals such as bats or shrews have been newly recorded here, the island's forests have been logged up to elevations of 2500 meters, and today if mammals have remained undiscovered it is because of their hidden or inaccessible habitat or their nocturnal habit.
自台灣特有種鳥類「帝雉」八十年前被記錄，台灣沒有新種鳥類再被發現；台灣近來雖出現蝙蝠、與食蟲目鼠類等哺乳動物新記錄種，但台灣伐木到兩千五百公呎高度，今天還能記錄到哺乳動物，和這些動物棲息地隱蔽、夜間活動的習性有關。
