最近本會受漁農自然護理署委託，調查本港家鴉巢的數量及位置，協助漁護署減少這種入侵鳥種對本港環境及生態構成的威脅，假如會員或會友發現家鴉巢，或發現家鴉在某個固定位置經常出沒，甚至銜著樹枝等可築巢的物料，請即以電郵(hkb ws@h kbws.org.hk)或PM通知我們，最好能附以地圖或相片以確定位置。

謝謝。

香港觀鳥會謹啟

As you can see, AFCD have put up a great effort to control House Crow in HK, and the result is very good. Still the number of House Crow has not decreased very significantly. AFCD need to keep up with the work.
