Following the loss of green areas, forests, marshes and even the traditional four-walled courtyard architecture, it is not only cave bats that are under threat. Two years ago, at a house in Chu-tung's Juanchiao, there was a colony of nearly a thousand Pipistrelle Small House Bats. Now on one side of the building there is a large karaoke parlor, and at the back there is a building site.
隨著綠地、森林、沼澤，甚至四合院建築的消失，不只是洞穴蝙蝠受威脅；兩年前竹東軟橋一戶民宅，還有近千隻家蝠，如今民宅左側多了一家大型 KTV，屋後則有工地施工，準備蓋「販厝」。
