Estimated diurnal location data for birds on Saipan

Each row represents a single location for a bird. X and Y columns correspond to the estimated X and Y location, in UTMs, for a given bird on Saipan. Individual Bird IDs are in the Bird_ID column and a species identifier is given in the Sp column. Rows with NA mean that the bird was not located during that movement interval数据集的每一行对应一只鸟类的单次定位记录。其中X、Y列分别代表塞班岛（Saipan）上某只鸟类的预估UTM（Universal Transverse Mercator，通用横轴墨卡托）坐标系下的平面坐标。Bird_ID列存储单只鸟类的唯一标识编号，Sp列则给出该鸟类的物种分类标识。带有NA值的行表示该鸟类在对应移动监测间隔时段内未被成功定位。
