白面白鶺鴒是ㄧ年四季都可以在台灣見到的鳥種。鶺鴒這ㄧ類的鳥喜歡在靠近水邊的開閣草地或馬路上遊蕩,行進時常常是快步走走停停,還不時地上上下下擺動長長的尾巴,遠遠的就可以見到牠們搖晃的動作了,而如果很明顯的發現黑白的對比色,那就是白鶺鴒了。
鶺鴒科鳥類在飛行的時候,喜歡在振翅之後略作休息,等身體下降到某一個程度時再繼續鼓翼,使身體上升。這種收翅和鼓翼交替運用之下,便形成了像波浪般的飛行路線。

白面白鶺鴒是白鶺鴒類三種亞種中的其中一種:
1.白面白鶺鴒,臉頰白淨,喉部至胸前都是黑色。
2.白鶺鴒,眼睛有著細黑色的過眼線,上胸僅有一小塊黑色。
3.黑眼線白鶺鴒,同樣也是帶著黑眼線,不過喉部至上胸前都是黑色,類似白面白鶺鴒。

白鶺鴒和黑眼線白鶺鴒都是來台灣渡冬的冬候鳥。

白面白鶺鴒的基礎資料如下,參考自<台灣鳥類全圖鑑>、<台灣野鳥圖鑑>

[型態特徵]
繁殖羽:頭頂至背部黑色,面部全白色。翼黑色,有明顯白斑。喉及前胸黑色,腹面白色,腳黑色。

非繁殖羽:頭頂至背部灰色,其餘部份皆相同。

[生態習性]
常迅速在地面快跑,並啄食地上昆蟲。放慢腳步或停立時,會不斷上下擺動尾巴。飛行時呈波浪形,並會發出有節奏的"嘰嘰嘰、嘰嘰、嘰嘰嘰"鳴叫。

[棲地分布]
分布於歐、亞、非三洲,在台灣廣泛見於平地至中海拔山區。
