The Taiwan New Year Bird Count (Taiwan NYBC) is a citizen science project that aims to monitor the status and trends of migratory waterbirds in Taiwan proper and its outlying islands. It was launched by the Taiwan Wild Bird Federatiopn (TWBF), the Wild Bird Society of Taipei (WBST), the Kaohsiung Wild Bird Society (KWBS) and Taiwan Endemic Species Institute(ESRI) in December 2013. The monitoring methods of the Taiwan NYBC follow the basic principles laid out in the more commonly known Christmas Bird Count. Over the course of 23 days from mid-December to early January (with January 1st as a midpoint), volunteer teams choose a 24-hour period to count all the birds within a circular sample area having a radius of three kilometers. Species, abundance, location, date, start time, end time, party size, survey method and weather are all recorded. Survey methods including line transect, counting flocks, area search, amongst others. This data provides valuable information about the distribution and community composition of Taiwan’s wintering avifauna. This has importance for conservation goals along the East Asian-Australasian Flyway as it offers an in depth look at the site usage of a number of migratory bird species. At the national level, findings are shared with government agencies such as Taiwan's Ministry of the Interior. Internationally, the data is shared with Wetlands International for use in the Asian Waterbird Census. 臺灣新年數鳥嘉年華(NYBC Taiwan)是2013年冬天啟動的全國性的公民科學計畫,目標在於監測台灣及周邊島嶼之度冬水鳥的族群狀態與趨勢。主辦單位包括社團法人中華民國野鳥學會、社團法人台北市野鳥學會、社團法人高雄市野鳥學會及行政院農業委員會特有生物研究保育中心。NYBC Taiwan的監測原則,依循北美洲耶誕節鳥類調查(Chirstmas Bird Count, CBC)的方法,於每年12月中旬至隔年1月中旬的23天內 (以1月1日為中點),每個樣區圓會有一組調查隊在期間內選擇一天或連續24小時,在半徑三公里的樣區園內執行鳥類調查。觀察到的鳥種、數量、地點、起始時間、結束時間、調查人數、調查方法和天氣狀況等資訊都會記錄。調查方法包括穿越線調查法、群集計數法、地區搜尋法和附加紀錄。NYBC Taiwan所產出的資料集為台灣冬季鳥類相提供相當重要的資訊。目前資料亦提供給行政院環境保護署及國際濕地聯盟(Wetland International)作為開放資料。

Geographic Coverage

The geographic scope of the data covers Taiwan proper and its outlying islands, including the Penghu Archipelago, the Matsu Archipelago, the Kinmen Islands and the Dongsha Islands. Taiwan proper is asubtropical biodiversity-rich mountainous island located at the intersection of East and Southeast Asia. Because the eastern two-thirds of the island is covered by high mountains, most human activity occurs on the flat plains and rolling hills of the western third. Croplands are mainly found in western Taiwan as well as eastern Taiwan's Rift Valley. The total area of cropland in Taiwan was 710,515.15 ha in 2017 (data source: Ministry of the Interior, Taiwan). Of this, about 20.67% was comprised of rice paddy fields (146,857.27 ha; data source: Council of Agriculture, Taiwan). 資料集的地理範圍涵蓋台灣本島及其離島,包括澎湖、金門、馬祖和東沙群島。 台灣是一個多山的島嶼,位於亞熱帶東亞,生物多樣性豐富。由於台灣東部三分之二為山區,大部分人類活動在島嶼西部三分之一的平原和連綿起伏的丘陵上。 大部分耕地分布於西部平原和丘陵,沿台灣東部縱谷有小面積農地。2017年台灣耕地總面積為710,515.15公頃(資料來源:行政院內政部)。其中,稻田約佔 20.67%(146,857.27 公頃;資料來源:行政院農業委員會農業委員會)。

Sampling Methods

Rules for the Taiwan NYBC are based off the basic principles set out in the Christmas Bird Count. Over the course of 23 days (with January 1st serving as a midpoint), volunteer teams choose one 24-hour period to count all the birds within a circle sample area whose radius is three kilometers. Routes within sample areas are provided for teams by the organizers. Teams are composed of at least one leader, at least one person experienced in birdwatching and surveys, and supporting volunteers. Group numbers could range from as few as three to over 100. While doing their count, teams record species name, number of individuals, location of route(s)/observation area, date, start and end time, number of participants, survey methods and weather conditions. Survey methods vary and include line transects, counting flocks, area searches, and others.

Study Extent The geographic scope of the data covers Taiwan proper and its outlying islands, including the Penghu Archipelago, the Matsu Archipelago, the Kinmen Islands and the Dongsha Islands.
Quality Control The date, time, and location of the survey should be fixed as regularly as possible. Double counting of individual birds should be avoided. Volunteers are also encouraged to do their best to record all species and individuals when doing their surveys in order to show the complete abundance of birds in a plot circle.

Method step description:

  1. 1. Organizers plan the survey period and mascot for the year's count. 2. Teams are created by site leaders to prepare for the Taiwan NYBC. Actions include designing site circles, recruiting volunteers, selecting survey dates, and assigning tasks within a specified range. Team leaders decide the survey methods used and surveys routes to use within their provided plot circles.They then report the survey results to the organizers. 3.Organizers compile and summarize survey results submitted by team leaders.

Additional Metadata

Purpose This citizen science project aims to collect occurrence data of migratory birds wintering in Taiwan propoer and its outlying islands. It also looks to assess the population trends of selected target species. 本計畫目標在於收集台灣冬季候鳥的出現紀錄,並評估目標物種的族群趨勢。
Maintenance Description Participants collect data annually each winter. The data will also be updated annually. 參與者每年冬天都會執行調查。 每年都會更新資料。
