聽聽看大卷尾的鳴叫聲，於2024年8月14日在種種看屋頂農場錄製。
Listen to the call of a Black Drongo recorded at Farm for Change on August 14, 2024.
大卷尾（學名：Dicrurus macrocercus，英文：Black drongo）為一種原產於台灣、東南亞和南亞的食蟲鳥類。在農場，我們觀察到大卷尾在不同的植物、水塔及屋頂上棲息，尋找昆蟲的蹤跡。
The Black Drongo (Dicrurus macrocercus) is an insectivorous bird native to Taiwan, Southeast and South Asia. On the farm, we observed it perching on different plants, the water tower, and the roof, looking out for insects.
我們大多在上午6~8點、下午3~4 點和傍晚6~7點之間錄到大卷尾的鳴叫聲。
We recorded most Black Drongo calls between 6:00~8:00, 15:00~16:00, and 18:00~19:00.
頻譜圖顯示大卷尾鳴叫聲的頻率如何隨時間產生變化。為了更清楚地呈現聲音的形狀，我們在明信片上使用了這段大卷尾錄音的頻譜圖。
The spectrogram shows how the frequency of the call varies over time. In order to show the shape of the sound more clearly, on the postcard we used a spectrogram from this recording of the Black Drongo instead.
