烏頭鶲 Formosan Bulbul

學名: Pycnonotus taivanus

英名: Formosan Bulbul

Family : Pycnonotidae (鵯科). Length: 18-19 cm.

又名台灣鵯,為台灣特有種,只分佈在台灣東部和南部。雖然在某些地區相當普遍,此鳥種仍被列為易危,因棲地的破壞和同屬鳥種白頭翁雜交造成數量減少,此兩鳥種分佈在某些地區重疊,且有白頭翁因宗教因素被放生至烏頭翁棲地。

中等體型(19厘米)的鵯,頭白,頂冠及髭紋黑色;下顎基部有一橙色小點斑;上體橄欖色,兩翼及尾褐色,邊緣橄欖黃色;下體近白,胸灰,兩脅偏褐。頭頂和枕黑色、眼先及耳羽白而帶銀皮黃色、喉白、髭紋呈黑色、近下嘴基部具一小形橙紅點斑、後頸淺土褐色,背、肩、小覆羽以及腰羽概污灰褐;大覆羽、飛羽和尾羽均暗褐,外緣以鮮橄欖黃,下體皮黃白,脅和覆腿羽染以灰褐色,尾下覆羽具橄欖色羽緣;虹膜-深褐,嘴-黑色,腳-黑色。特殊的肺部構造使它們能持久地飛行而不會感到呼吸困難。
