彩鷸

今天(31/5)約11.30ａ．ｍ，在米埔３號鳥屋近右面淺水有一對彩鷸披繁殖羽，十分搶眼，他們帶著兩隻趣緻的幼鳥，可惜無帶相機。

各師兄／姐有空可試下睇下佢地是否還在，並影的相和大家分享。

昨天見到隻媽媽，她看來好空閒，只顧自己找吃，只讓爸爸照顧小彩鷸。今日(1/6) 只見到兩隻小彩鷸，其中一隻可能凶多吉少。

多謝提供美麗的相片！
各位帥兄/姐可否解釋為何彩鷸和一般的雀鳥不同，雄鳥顏色反而無較鮮艷及負責帶幼鳥。

根據剛由維基找到的資料(http://hudong.com//wiki//%E5%BD%A9%E9%AC.

彩鹬 - 生长繁殖
彩鹬繁殖期5-7月。营巢于浅水外芦苇丛或水草丛中，也在水稻田中营巢。巢主要由枯草构成，通常置巢于芦苇或水草或稻秧间浅水处的草堆上或土台上。每窝产卵3-6枚，通常为4-5枚。卵为卵圆形和梨形，棕黄色和黄色，被有红褐色、黑褐色或血红色斑点，卵的大小为32-40mm×22-26mm，平均36mm×26mm。一雌多雄制，一个雌鸟与数个雄鸟交配，并产数窝卵，分别由不同雄鸟孵化，孵化期约19天。

並且由雌鳥向雄鳥求偶，真是陰陽倒置。
