10月9日是世界候鳥日,候鳥與香港有何關係?
每年有數以萬計候鳥途徑香港,部分更會在港過冬。候鳥選擇香港作中途補給站或者度冬地,原因之一是后海灣濕地有相對穩定的食物供應。🐛
瀕危物種黑臉琵鷺是后海灣的「訪客」。然而,根據本年度全球同步普查,香港黑臉琵鷺數目顯著下降,后海灣只有336隻,過去七年間跌幅達15%,反映濕地正面臨發展威脅。😰
身形細小、只有手掌般大的勺嘴鷸,亦會在后海灣覓食,其情況比黑臉琵鷺更嚴峻,全球少於700隻,被列為極度瀕危物種。要保育雀鳥,首要是保育濕地,切勿破壞牠們的棲息及度冬地,大家不妨花數分鐘觀看以上片段,了解濕地對候鳥的重要性。❤️
【Wetland: Home to the Endangered Birds】
Oct 9 is the World Migratory Bird Day. Do you know Hong Kong is a haven for migratory birds?
Myriads of migratory birds fly over Hong Kong every year, with some of them staying put for winter. Hong Kong is chosen as a migration stopover site or wintering ground largely because of a relatively stable food supply in the Deep Bay wetland. 🐛
Black-faced Spoonbill, an endangered species, is a regular winter visitor to Deep Bay. However, the International Black-faced Spoonbill Census 2021 recorded a notable decline in Hong Kong population, with only 336 indiviuals in Deep Bay. The number dropped by 15% over the course of 7 years reflected increasing threats posed by development to Deep Bay wetland. 😰
Spoon-billed Sandpiper, which also is a visitor to Deep Bay, is facing an even grimmer scenario. Its world population is only about 700 individuals and has been listed as critically endangered. To conserve endangered species, we must first conserve wetland. Wanna learn more about the significance of wetland? You can watch the video above. ❤️
