2021-06-25 chi Taiwan Wild Bird Federation Bird Records Database (TWBF Database), the first and the largest web-based biodiversity citizen science database of Taiwan, has collected a large number of birdwatching checklists provided by more than 3,000 users. From 1972 to 2017, the TWBF Database accumulated 1,853,589 bird records within 102,716 checklists, covering nearly all area and almost 90% of the 653 bird species of Taiwan Island and its outlying islands.

During the surveys, birdwatchers detected and identified bird species with naked eyes, through binoculars and telescopes, or by listening to the bird sounds, and filled out the checklists with species, number of individuals, location, date, start time, duration, sampling protocol, and survey effort. Birdwatchers submitted their checklists to TWBF Database via a web form that validated the content and format of the entered records. To ensure the quality of data, each checklist was requested to at least provide the information of survey location, date, time, and the completeness of species lists (users could choose to submit a complete checklist, including all the species detected, or an incomplete checklist with only certain species they concerned). We obtained the raw data from TWBF database and standardized it according to the Darwin Core format. The original contents were kept as much as possible during the data conversion unless there was an obvious mistake. Most of the checklists lack precise coordinates information because the TWBF database had requested only textual descriptions of survey location for a long time. Therefore, we inferred and restored the approximate area where each event took place according to the description, then located the latitude and longitude at a vicinal bird-watching hotspot, the location with suitable habitat, or the geographical center of the area. The uncertainty of coordinate inference was within 1000 meters. For those checklists stating further details about the sampling methods, we looked into the descriptions, defined the practices as transects, point counts, or area searches, and quantified the corresponding sampling efforts with transect length, time duration, or area covered. Surveys were conducted by birdwatchers and local birdwatching societies between 1972 and 2017 throughout the land and sea under the jurisdiction of the government of the Republic of China (widely known as “Taiwan”), including Taiwan Island and its outlying islands, which are scattered across Taiwan Strait, Pacific Ocean, and the South China Sea. Each provided birdwatching checklist represents one sampling event. From July 8th, 1972 to April 9th, 2017, a total of 102,716 sampling events were conducted. The main sampling methods include transects, point counts, and area searches. The checklists with abnormal sampling time, doubtful or overly vague spatial information, as well as uncertain species identification, had been regarded as invalid data after confirmation in multiple ways and eliminated from the publishing version. The contents of all versions during data conversion were kept to track the modifications.
