251 Barn Swallow 家燕
Tsim Bei Tsui 尖鼻嘴  
13/4/2003
1 小燕聽到母燕回來,急轉身。但我奇怪,母燕口中含著食物,如何鳴叫呢﹖小燕則 不斷「吱吱」叫。

2 母燕快到,小燕張口拍翼,保持臨空的穩定。

3 空中加油式哺育開始,母燕來回餵了幾次。

Are you intended to make the color so strange for copyright purpose.

Thanks Daniel.
 
I'm use mac, it is a bit "green" on a CRT PC with win98, but OK on LCD win 2000 and Mac.
 
I will try to set my mac's color again.
 
you know it is taken in cloudy day, I use cloudy WB, and I have add some contrast on curves and add a bit saturation .

"但我奇怪,母燕口中含著食物,如何鳴叫呢﹖"
 
今天在大埔滘也見到紅耳鵯一邊含著蜻蜓一邊叫。
 
其實你我都可以口含食物說話,只要呼出的空氣有出路便可發聲,但是因為口形和 舌頭受制,發音會不清楚。
 
猜想鳥類鳴叫時口形和舌頭的作用不大,所以口內有物也不大影響發音。
 
參考有關書籍,鳥類發聲的器官稱為鳴管,位於氣管的下端,不像哺乳類動物的聲 帶位於喉頭。
