Taiwan New Year Bird Count - a citizen science project of bird survey in winter

Latest version published by Taiwan Endemic Species Research Institute on Jun 24, 2021 Taiwan Endemic Species Research Institute

NYBC Taiwan is a citizen science project which aims to monitor the status and trends of wintering birds in Taiwan and its outlying islands. It was launched by the CWBF, the Wild Bird Society of Taipei (WBST), the Kaohsiung Wild Bird Society (KWBS) and ESRI in December 2013. The monitoring methods of NYBC Taiwan follow rules laid out in the more commonly known Christmas Bird Count. During the 23 days from mid-December to early January (with January 1st as the midpoint), volunteer teams choose a 24 hour period to count 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 and additional records are used. This data set provides valuable information about the distribution and community composition of Taiwan’s avifauna in winter. This data is distributed nationally to groups like Taiwan’s Ministry of the Interior and internationally where it contributes to Wetlands International’s International Waterbird Census.

Geographic Coverage

The geographic scope of the data covers Taiwan proper and its outlying islands, including Penghu, Kinmen, Matsu and Dongsha Islands. Taiwan is a mountainous island with diverse biodiversity located in subtropical East Asia. Because the eastern two-thirds of Taiwan is covered by high mountain ranges, most human activities occur on the flat plains and rolling hills of the western third of the Island. Most croplands are distributed in the western plains and hills, and there is a small area distributed along the rift valley of eastern Taiwan. The total area of cropland in Taiwan was 710,515.15 ha in 2017 (data source: Ministry of the Interior, Taiwan). Of this area, about 20.67% was composed of rice fields (146,857.27 ha; data source: Council of Agriculture, Taiwan).

Taxonomic Coverage

Birds. Most species are migratory bird species, especially the migratory shorebirds and waterbirds. All birds were recorded if the volunteers detected them.

Design Description During the 23 days from mid-December to early January (with January 1st as the midpoint), volunteer teams choose a 24 hour period to count the birds within a circular sample area having a radius of three kilometers.

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 Penghu, Kinmen, Matsu and Dongsha Islands.
Quality Control The date, time and location of the survey should be fixed as regularly as possible. Try to avoid double counting.Count as much as possible to show the complete abundance of the birds in the entire plot circle.

Method step description:

  1. 1.The organizer plans the survey date range and representative bird species. 2.The leaders of each sites area lead the team to perform tasks, including designing a site circle, recruiting volunteers members, selecting survey dates and assigning tasks within a specified range. And the leaders plan the survey method and route range of the bird counting within the plot circle, and the report of the bird counting results. 3.The organizer summarizes the survey results submitted by leaders of various districts.

Additional Metadata

Purpose This project aims to collect the occurrence data of migratory birds in winter in Taiwan, and to assess the population trends of the target species.
Maintenance Description The participants collects data every winter. Basically the data will be updated annually.
