🐦American Robin
旅鶇（學名：Turdus migratorius）亦稱美洲知更鳥（英語：American robin），是鶇屬下的一種候鳥，雖然叫做美洲“知更鳥”，但實際上旅鶇與知更鳥並不是一個屬的生物，二者之間也沒什麼親緣關係。旅鶇廣泛分佈與北美洲，會從加拿大、阿拉斯加飛往墨西哥中部及附近的太平洋沿海地區過冬。它是美國康涅狄格州、密歇根州和威斯康星州的州鳥。有時被認為是現存種群數量僅次於紅翅黑鸝的北美洲陸禽。旅鶇有七個亞種，但只有南下加利福尼亞州的T. m. confinis特征明顯。 旅鶇在白天出沒，晚上則聚集在一起歇息。其食物包括無脊椎動物和植物果實。夏季回歸後不久就會開始產卵，是北美洲最早開始產卵的鳥類之一。它們的巢穴以草葉、樹枝和羽毛等組成，內部墊有細草，外部塗有泥巴。它們黎明時分開始鳴叫。 鷹等大型猛禽是旅鶇的天敵，群居的旅鶇會互相警戒以防止被捕食。褐頭牛鸝會將自己的卵寄生在旅鶇的巢裡，但後者一般並不會隨之接受這些卵。
