Laboratory #3: Distance Based. Elron Oscar

The experiment took place at York University on Friday, October 3rd 2014, from 2:30-4:30. The weather was approximately 5 degrees Celsius with rain and strong breeze. The experiment was conducted at York University woodlot area on the south side of York closer to Keele Street. For this experiment, it was done with Mahal Annes, Enrique Sapena Ventura , and Yu Xiao. For grasslands and the woodlot area, 5 transect measuring tape was placed randomly. About 20 meters of transect tape was randomly placed. When walking down the transect line, we recorded the number of birds spotted and the species of the birds. The birds can be identified with a bird guide book, if unable to identify put "unknown species". If not bird was spotted, put "none". Binoculars were used to get a better accuracy of what the species of birds may be. Approximation was for determining how far the bird was relative to where the transect measuring tape is placed. The wind speed was measured under a categorical scale called Beaufort Scales.本实验于2014年10月3日周五在约克大学（York University）开展，实施时段为14:30至16:30。当日气温约为5摄氏度，伴有降雨与强风。实验场地位于约克大学南侧、紧邻基尔街（Keele Street）的林地区域。本次实验的参与人员包括Mahal Annes、Enrique Sapena Ventura与Yu Xiao。针对草原与林地生境，研究人员随机布设了5条样带卷尺，单条样带的布设长度约为20米。沿样带行进观测时，需记录所发现的鸟类数量与物种信息：若无法识别具体物种，则标注为‘未知物种（unknown species）’；若未观测到任何鸟类，则标注为‘无（none）’。为提升鸟类物种识别的准确性，实验使用了双筒望远镜（binoculars）。研究人员通过近似估算确定鸟类与样带卷尺布设位置的相对距离。风速采用蒲福风级（Beaufort Scales）进行分类测定。
