地理涵蓋範圍

TWBF Database is a nationwide database which covered the island of Taiwan, its offshore islands, and surrounding seas.

分類群涵蓋範圍

A total of 586 species and 2 subspecies, as well as 16 species combinations and 3 domestic types, were recorded, covering about 90% of the bird species have been recorded in Taiwan. The classification system followed the 2018 edition of the eBird/Clements taxonomy (Clements et al. 2018).

時間涵蓋範圍

計畫資料

Integrating the historical bird records of TWBF Database, and converting the records to eBird database format and Darwin Core.

取樣方法

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.

方法步驟描述:

1. 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.
2. 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).
3. 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.
