On May 8th, 2021, birders and nature enthusiasts around the world joined in the second ever Global Big Day bird count organized by Global Birding and powered by the eBird online platform. During the event, nearly 52,000 people from 192 countries recorded 7,234 species on 133,887 checklists! This was no small feat and could be celebrated as an international effort for birding and citizen science.
The Black-faced Spoonbill (Platalea minor),whose global population has risen from a known 288 in 1990 to over 5,000 this year,is one of Asia's great conservation successes. This endangered migratory waterbird endemic to East Asia has not just become iconic in countries along the East Asian-Australasian Flyway, but has won over the hearts of enthusiasts and the public around the world. Its conservation success relied on the power of partnership and cooperation at both the local and international level. Taiwan, which sees over half the global wintering population and where it is affectionatelyknown as “Hei-Pi” (since the “hei” and “pi” of its Chinese name sound like “happy”), made outsized contributions to that success. Here we look at that story.
美國康乃爾大學鳥類實驗室(The Cornell Lab of Ornithology)除了發展廣為人知的eBird之外，還有一個Macaulay Library (中文多譯為麥考利資料庫)。麥考利資料庫由康乃爾大學鳥類實驗室創立於1929年，當初稱為Cornell Library of Natural Sounds資料庫，第一份鳥類錄音是Peter Paul Kellogg and Albert R. Brand使用幾乎和汽車一樣大的自製集音盤在Ithaca City Park陸下的錄音，目前還可以在資料庫當中聽到：
自然錄音是一門專業，我自己從碩士班以鳥類的鳴叫行為生態作為研究題目開始學習，到現在其實也只瞭解了「如何錄到清楚可辨識的單音軌聲音的器材」這件事情而已，其他更高深的比如如何錄聲景(soundscape)或者立體聲(stereo)就不在本文的討論範圍之內。這邊會推薦的基本上都是我使用過的器材，然後也會建議一些網路評價不錯但我沒買過的。如果要查更多資訊的話，用以下關鍵字去搜尋可以找到許多不錯的英文網頁：portable recorder, field recording
