【褐漁鴞登場！】

褐漁鴞 𝐾𝑒𝑡𝑢𝑝𝑎 𝑧𝑒𝑦𝑙𝑜𝑛𝑒𝑛𝑠𝑖𝑠𝑐𝑎𝑛 係本港罕見嘅夜行性貓頭鷹，行踨隱蔽，肉眼難以發現。聽聞佢哋會喺大嶼山近水源嘅地方出沒，就等鳥會調查員查證一下！

上兩個月，我哋喺大嶼山展開「被動聲學監測研究」，透過錄低雀仔叫聲辧認雀鳥物種。短短兩個月內，我哋就喺幾個研究地點持續錄到褐漁鴞嘅鳴唱聲—深厚而有迴響嘅「Hoo-Hoo」。而進行定期夜間調查期間，調查員更喺兩個地點親眼目睹褐漁鴞！

未來，我哋希望繼續監測及記錄本地貓頭鷹嘅叫聲，了解更多佢哋嘅鳴叫規律及生活習性，為保育貓頭鷹提供重要基礎資訊。

[Wild Brown Fish Owl appeared!]

The Brown Fish Owl (𝐾𝑒𝑡𝑢𝑝𝑎 𝑧𝑒𝑦𝑙𝑜𝑛𝑒𝑛𝑠𝑖𝑠𝑐𝑎𝑛) is a rare nocturnal owl species in Hong Kong, with elusive behavior that makes it difficult to spot. There is a rumor that they can be found in the vicinity of water sources on Lantau Island, so our team of researchers set out to verify this information.

Two months ago, we started the passive acoustic monitoring research in Lantau Island, using recordings of bird calls to identify bird species. Within just two months, we have consistently recorded the vocalizations of Brown Fish Owls - deep booming Hoo-Hoo, at several locations. Furthermore, during regular nocturnal surveys, our researchers have even witnessed Brown Fish Owls firsthand at two survey sites!

Continuously monitoring and documenting the diverse calls of local owls allows us to gain a better understanding of their vocalization patterns and behaviour. This valuable information serves as a crucial foundation for owl conservation efforts.
