在奧萬大森林遊樂區裡，住著一群羽色亮眼，外型小巧可愛的青背山雀，每年的四月起，他們就會在園區內利用樹洞岩穴來築巢，南投林區管理處的工作人員，為了窺探這些鳥兒的繁殖行為，特別訂製了鳥巢箱，並且架設針孔攝影機來監測他們，於是青背山雀的神秘面紗漸漸被展開。型態特徵：青背山雀全長約12公分，頭部藍黑色，有光澤，頰耳羽和後頸有白色斑背部黃綠色；腹面亮黃色，中央有黑色縱帶，雄鳥腹面之黑色縱帶較窄且短。生態習性：青背山雀長單獨、成對活小群出現於樹林中、上層枝葉間，環境適應力強，甚至會在果園中活動；冬季會遷移至低海拔山區，有時甚至到低海拔平原度冬，春季才漸漸移棲至高山繁殖：聲音輕快、悅耳而多變，如有「急、急－降－」、「啾－、啾－」及「居、居、居」等：以昆蟲、嫩芽、漿果等為時、生性活潑不怕人。 Abstract: A group of petite, cute green-backed tits with beautiful feathers and eyes lives in Taiwan’s Aowanda Forest Recreation ... Area. Every April they build nests in caves or tree holes in the park. Staff of the Nantou Forestry Management Office custom designed a nest box with a built-in camera to watch the reproduction and behavior of these birds. Thus the habitual behavior of these birds is no longer a mystery.
