紅胸鶲(學名:Ficedula parva)與紅喉鶲(學名:Ficedula albicilla)原本是歸類在同一種不同亞種,近年已將紅胸鶲獨立出來,兩者冬羽相似(還是有不明顯的差異,請參見紅胸鶲冬羽紅喉鶲冬羽),紅喉鶲就是夏羽只在喉部紅【參見紅喉鶲(文末)】,紅喉鶲則是從紅部紅到胸部。

不論是紅喉還是紅胸,在台灣都是較少見的過境鳥(主要在東南亞度冬),有鶲科停棲固定點行捕食的習性,此羽自2017年過境期出現在石門水庫就留了下度冬,特別的是一直維持著夏羽的紅胸形態,相當少見,2017年12月9日是我第一次去紀錄,這是我的補考,有了前一次的經驗加上較佳的天氣,畫面是有進步。【之後再去拍攝一次,有搶先的覓食版,可以一起參考】.學名:Ficedula parva
