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.本次实验于2014年10月3日星期五在约克大学（York University）开展，实验时段为当日14:30至16:30。当日气温约5摄氏度，伴有降雨与强阵风。实验地点设置在约克大学南侧紧邻基尔街（Keele Street）的林地（woodlot area）区域。参与本次实验的人员包括Mahal Annes、Enrique Sapena Ventura与Yu Xiao。针对草原与林地区域，我们随机布设了5条样带卷尺（transect measuring tape），单条样带的随机布设长度约为20米。沿样带行进过程中，需记录观测到的鸟类数量及对应鸟类物种。可通过鸟类图鉴识别鸟类，若无法识别物种，可标注为“未知物种（unknown species）”；若未观测到任何鸟类，则标注为“无（none）”。实验使用双筒望远镜（binoculars）以提升鸟类物种识别的准确率。采用目测法估算鸟类相对于样带卷尺布设位置的距离。风速通过蒲福风级（Beaufort Scales）分类量表进行分级测定。
