Lab3: Birds species observed in York University

This experiment was performed on Monday September 28, 2015 in York university at Danby woodlot and Stong pond region. Temperature was around 21°C with cloudy weather and a cold breeze. Experiment was performed between 2:45 - 4:45 pm. Group members who participated in this experiment were: Sarah, Sharon, Anosha and Sayed. Grassland was the first location to start bird observation, abundance was determined by placing a 40 m long transect tape randomly in a straight line and the experimenter would walk along the tape and observe every bird in sight for 5 minutes each meter. This process was replicated 5 times in Grassland and then another 5 times at the Danby woodlots except for changing the transect length to 30 meters. What is worth mentioning is that one virtual line was made across the pond to observe geese at the Stong pond area. Characteristics of each species were written and then identified using the guiding book and the guides provided on the course blog.

本实验于2015年9月28日星期一，在约克大学（York University）的丹比林地（Danby Woodlot）与斯通池塘（Stong Pond）区域开展。实验当日天气多云并伴有冷风，气温约21℃，实验时段为当日下午2:45至4:45。参与本次实验的小组成员包括Sarah、Sharon、Anosha与Sayed。本次鸟类观测首先从草地生境启动：通过随机布设一条40米长的样带卷尺，实验者沿样带行走，对每米范围内可见的鸟类进行时长5分钟的观测，以此统计鸟类丰度。该观测流程在草地生境重复5次，随后在丹比林地重复5次，仅将样带长度调整为30米。值得说明的是，为观测斯通池塘区域的雁类，实验人员布设了一条横跨池塘的虚拟样线。各物种的形态特征均被详细记录，并通过课程配套的指南手册与课程博客提供的参考资料完成物种鉴定。
