【橙眼睛幽幽的看著這孤城】
「Hoo、Hoo、Hoo」夜闌人靜嘅山頭上，傳出一把低沉、有迴響嘅神秘叫聲～
究竟係邊個叫？原來係鵰鴞 (Bubo bubo) ——香港最大型嘅貓頭鷹，身長達60厘米，展翼長達2米，擁有一雙迷人嘅橙色眼睛。
由於鵰鴞偏好樹木疏落、巨石嶙峋嘅山坡，大嶼山成為最合適不過嘅棲息地同繁殖地。但係，佢哋晝伏夜出、行蹤隱秘，要尋找佢哋身影十分有挑戰性。
好彩有「被動聲學監測」技術，令我哋可以不分晝夜錄低四周嘅聲音，有助記錄鵰鴞嘅行蹤。目前為止，我哋已經成功記錄到鵰鴞嘅警戒叫聲同歌聲！
至於鵰鴞叫聲代表咩意思？又會喺咩時間、日子、地方叫呢？有待我哋繼續研究同探索！

[Exploring the Mysterious Life of the Eurasian Eagle-Owl through Calls]
“Hoo, Hoo, Hoo” on a quiet night atop the mountain, a mysterious low and echoing call can be heard
Who could be making that sound? It's actually the Eurasian Eagle-Owl (Bubo bubo), the largest owl species in Hong Kong, reaching a length of 60 centimeters and a wingspan of up to 2 meters 🪽 and possesses a pair of orange eyes.
Lantau Island, being characterized by varying elevations and diverse habitats with scattered trees and rugged slopes, provides an ideal environment for the Eagle-Owl to roost and breed.
Despite its large size, it only ventures out at night to hunt, keeping its whereabouts secretive and making it challenging to locate them.
We employ passive acoustic monitoring techniques, akin to raising ears in different locations at night, to listen for the calls of the Eagle-Owl, increasing our chances of recording their presence. In the preparatory stages of our research, we've already captured the alarm calls and songs of the Eagle-Owl in various locations!
The question remains: do the calls of the Eagle-Owl conceal any meaningful information? When and where do they prefer to call? These are aspects we will explore and study in the coming year.
