Data Collection of Pilot Experiment Balcony Birdwatching in City of Vaughan

Pilot observational study of bird frequency and behaviour in the city of Vaughan from the period of September 25, 2020 to September 28, 2020. The purpose of the study was to identify common bird species and observable behaviour in local neighbourhood locations. Every day during dusk, from 6:00 pm to 7:00 pm, 60-minute observations were conducted to maintain consistency in the time of observation between locations. Data was collected at one of the following sites each day, respectively: Davos & Pine Valley park, Crofters Pond, William Glan Jay Greenway Trail and Fossil Mountain Pond. An area located approximately 250 metres from the start of William Glan Jay Greenway Trail was chosen to maintain a singular point of observation consistent with other locations. A binocular was used to observe behaviours in locations where bird visibility was relatively low. Behaviours noted were accurately defined through ethograms used in an online peer-reviewed journal paper (Katajamaa et al., 2018).

2020年9月25日至9月28日期间，针对沃恩市（Vaughan）内鸟类出现频次与行为开展的先导性观测研究。本研究旨在明确当地社区区域内常见鸟类物种及可观测行为特征。每日黄昏时段（18:00至19:00）开展时长60分钟的观测，以确保各观测点位的观测时间保持一致。每日依次在以下一处观测点位采集数据：达沃斯松谷公园（Davos & Pine Valley Park）、克罗夫茨池塘（Crofters Pond）、威廉·格伦·杰伊绿道（William Glan Jay Greenway Trail）以及化石山池塘（Fossil Mountain Pond）。选取距威廉·格伦·杰伊绿道起点约250米的区域作为固定观测点位，以保障各点位观测方案的一致性。针对鸟类可视度较低的观测区域，使用双筒望远镜开展行为观测。本次记录的鸟类行为均通过一篇已在线发表的同行评议期刊论文（Katajamaa等，2018）中采用的行为谱（ethogram）进行精准界定。
