黑領椋鳥（學名：Gracupica nigricollis，英文：Black-collared Starling），為一種原產於東南亞大陸和中國的雜食性鳥類，並被引入台灣。在農場，我們觀察到牠在覓食、收集草作為築巢材料，在灑水器下納涼。
The Black-collared Starling (Gracupica nigricollis) is an omnivorous bird native to continental Southeast Asia and China, and introduced to Taiwan. On the farm, we observed it foraging, collecting grass as nest material, and cooling off under the sprinklers.
我們大多在上午6~9點和下午4~6點之間錄到黑領椋鳥的鳴叫聲。
We recorded most Black-collared Starling calls between 6:00~9:00 and 16:00~18:00.
頻譜圖顯示黑領椋鳥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黑領椋鳥錄音的頻譜圖。
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-collared Starling instead.
