說明
This is a project focusing on understanding avian communities in betel nut plantation and secondary forest in Taiwan. We collected the data in the breeding season (March to May) in 2015 and 2016 in a total of 80 sites in five counties in central Taiwan. There are 5 sampling points in each site and we collected avian community data in each point twice in each season.

取樣方法
Following a standard point count procedure (Buckland et al. 2005), we spent 6 minutes at each point to record the number of different bird species we saw and heard and the distance of each bird determined by Laser range finder (Nikon laser 1000AS).
| 研究範圍 | We conducted five point count surveys in 40 betel nut and 40 secondary forest plots in March to May 2015 and 2016 in central Taiwan. |
|---|---|
| 品質控管 | To avoid human error, the investigation was conducted by four professional investigators. For distance measurement, a laser rangefinder was used to obtain actual measurements, standardizing the investigators’ reference points. The taxonomic system follows the Checklist of Birds of Taiwan maintained by the Bird Record Committee of the Chinese Wild Bird Federation (Ding et al. 2023). |
方法步驟描述:
- 1. We identified homogenous patches of secondary forest and betel nut plantation below 1000 m above sea level using Google Earth software (Google Inc.) that are larger than 13.6 ha. 2. We then selected 40 secondary forest and 40 betel nut plantation plots that are at least 4 km apart from plot center. Within in each plot, we set up 5 sampling points along the established road system and each point was at least 200 m apart to avoid double counting. 3. Bird sampling was conducted within 4 hours after sunrise on clear day (without rain and strong wind). Each sampling point was surveyed twice in breeding season (March to May). 4. For each bird record, the bird species (the smallest taxonomic unit: species), number of individuals (number), horizontal distance to the observer (2015: 0-25m, 25-100m, >100m, flyover; 2016: taken every 10m as a band, flyover), and flock formation with more than five individuals were recorded. 5. For each sampling point record, investigation date (year, month, and day), starting time, observer, weather condition (clear, cloudy, overcast, fog, drizzle, or showers), and wind speed were recorded.
