Taiwan New Year Bird Count

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.

Sampling

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.

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 steps

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.

Birds. Most species counted as are migratory bird species, particularly migratory shorebirds and waterbirds. All birds observerd by volunteers are recorded. 鳥類。 大多數物種是候鳥，尤其是遷徙鷸鴴和雁鴨。參與者觀察到的所有鳥類都會記錄下來。

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）。
