中文摘要 | 本研究探討搭配鳥音回播的定點計數是否可以提升鳥類相調查效率。在台南縣崁頭山海拔 75-660 m地區進行實驗。結果發現,搭配鳥音回播在定點需要停留更久時間,但明顯減少需要的樣本數。回播使調查到的總鳥種數較少,但可以增加調查到的總個體數。本研究鳥音回播與定點計數同時進行,以致對調查者造成干擾,無法完全達到預期結果。我們認為在非繁殖季明顯缺乏鳥音線索的中高海拔山區的鳥類相調查,搭配鳥音回播的定點計數仍值得嘗試;並應採取播放一段時間之後,關掉音源再進行調查。雖然增加額外的鳥音播放時間,但應該可以有效減少樣本數;對於路途遙遠或可及性較低的中高海拔山區而言,有其應用上的價值。 |
英文摘要 | We explore if birdsong playbacks promote the efficiency in avifauna point-count surveys. We conducted fieldworks in Mt. Kantoushan, 75-660 m.a.s.l., southern Taiwan, in April and May 2008, the breeding season, and in November and December 2008, the non-breeding season. Surveys with playbacks detected more individuals but less species than that without playbacks. The playbacks also increased the required duration in a point count, but conspicuously reduced the required samples in a vegetation stand. Results suggest that birdsong playbacks might not be an appropriate method to promote the efficiency of point-count surveys for lower montane avifauna. This survey scheme, however, is still worth applying in remote districts since fewer sample requirements. |
