說明
Qigu District, located on the southwest coast of Taiwan, is full of natural and artificial wetlands and therefore one of the important bird habitats along the East Asian–Australasian Flyway (EAAF). For conservation and academic purposes, Taiwan Endemic Species Research Institute (TESRI) (currently known as Taiwan Biodiversity Research Institute, TBRI) initiated a long-term bird monitoring project in wetlands of southwestern Qigu in 2015. In the period of April 2015 to March 2021, bird censuses were conducted once a month at 6 sampling sites, resulting in 432 sampling events and 11,533 occurrence records. A total of 100,601 individual counts, grouped into 120 species and 36 families, were recorded. The most dominant family is Ardeidae, followed by Scolopacidae, Anatidae, Recurvirostridae and Charadriidae. This project is still in progress and the dataset may be updated irregularly in the future.

計畫資料
For conservation and academic purposes, Taiwan Endemic Species Research Institute (TESRI) (currently known as Taiwan Biodiversity Research Institute, TBRI) initiated a long-term bird monitoring project in wetlands of southwestern Qigu in 2015. Since then, bird censuses have been conducted once a month at 6 sampling sites in this region. This project is still in progress.

研究區域描述 | The study area of this project is the southwestern part of Qigu District (in Tainan City), which is located on the southwest coast of Taiwan (23.07206°N to 23.10149°N, 120.03645°E to 120.08831°E). The landscape of this region is composed of various natural and artificial wetlands (e.g. fish farms), and therefore provides suitable habitats for waterbirds, especially those migrating along the East Asian–Australasian Flyway (EAAF). Based on the weather data of the past 10 years (2013-2022) from the Qigu weather station (23.14719°N, 120.08619°E), the average temperature here is 24.1°C. The month with lowest temperature is January (17.3°C), while the month with highest temperature is July (29.2°C). The average annual precipitation is 1510.2 mm, and the seasonality of precipitation is typically obvious. From May to September, the monthly precipitation is above 160 mm, but it declines to less than 80 mm from October to April. |
研究設計描述 | This project is meant to establish baseline data of the avian community in Qigu wetlands by means of long-term periodic bird censuses at selected sampling sites. |

取樣方法
The monthly bird censuses at LHF, NFF, EFF and QGL were conducted using transect method (as shown in column “samplingProtocol” of the DwC Event Core). These transects are usually trails beside fish farms (at LHF, NFF, EFF) or along the levee (at QGL), with the length ranging from 0.826 km to 3.129 km. In contrast, monthly censuses at AFR and AFF were conducted using counting flocks method, which means counting flocks of birds within a predefined area. The sampling areas of AFR and AFF are 9.8 ha and 22.4 ha, respectively. Bird censuses were all conducted during daytime (mostly between 9 a.m. and 5 p.m.), with no strict limitation on the starting time and duration of each census.
研究範圍 | Six representative sites within southwestern Qigu District were selected as the sampling sites of this monitoring project (as shown in column “locality” of the DwC Occurrence Extension), including Lighthouse Fish Farms (LHF), North Fish Farms (NFF), East Fish Farms (EFF), Qigu Levee (QGL), American Fish Farm Ruins (AFR) and American Fish Farms (AFF). Bird censuses were conducted once a month at these six sampling sites from April 2015 to March 2021. The main habitat type within these sampling sites are fish farms for clams (Meretrix lusoria) or milkfish (Chanos chanos), while the habitat environment still slightly differs between sites. The centroid coordinates (WGS84) of 6 sampling sites: LHF: 23.09003°N, 120.04050°E; NFF: 23.08897°N, 120.05879°E; EFF: 23.08006°N, 120.06647°E; QGL: 23.07881°N, 120.08044°E; AFR: 23.09383°N, 120.08439°E; AFF: 23.09788°N, 120.08256°E |

品質控管 | All of the monthly bird censuses were carried out by 1-3 experienced and well-trained bird observers. To keep the quality steady, only 5 observers (including 2 main observers and 3 occasionally assistant observers) have been involved during the time coverage of this dataset (April 2015 to March 2021). All of the occurrence records were integrated and examined after each census. Any uncommon or abnormal records will be confirmed, and modifications will be made if necessary. The taxonomy information in this dataset is organized based on the eBird Taxonomy v2022 (Clements et al. 2022) and the 2023 TWBF Checklist of the Birds of Taiwan (Ding et al. 2023). |
方法步驟描述:
- All of the six sampling sites and the corresponding census methods were determined at the beginning of this project. For the transect censuses (at LHF, NFF, EFF and QGL), a team of observers walked along a predefined transect and recorded the birds nearby. For the counting flocks censuses (at AFR and AFF), observers counted and recorded the birds within a predefined area, which is typically composed of several fish farms. Observers used binoculars (typically 10x42) and/or monoculars (20-60x) to detect and observe birds in all censuses, and recorded bird species as well as the number of individuals. Birds seen or heard by the observers were all recorded, except for those birds only flying through sampling area without perching or foraging behaviors. The weather condition determined by visual observation was also recorded for each census (presented as a categorical variable in the DwC Measurement or Facts Extension). Each monthly census at each of the six sampling sites is regarded as a sampling event (as shown in column “eventID” of the DwC Event Core). It should be noted that from April 2015 to around June 2018, all of the bird occurrences within a single sampling event were recorded at the same coordinate, which is the centroid coordinate of the sampling site. However, the bird occurrences were recorded at the coordinate of several distinct locations, which correspond to different sections along the transect or different districts within the site, since around June 2018 (the time points slightly differ between sampling sites). The change of recording protocol can be observed through columns “locationID”, “decimalLatitude” and “decimalLongitude” of the DwC Occurrence Extension.
