Bird Species Abundance in York University's Danby Woodlot

This experiment was conducted in order to determine the abundance of bird species in the York University Danby woodlot area.The procedure for this experiment consisted of repositioning a 10 meter by 10 meter belt transect square to 10 different locations in York Univeristy's Danby woodlot area (5 replicates in the woodland area and 5 replicates in the grassland area). The abundance was estimated by counting and identifying the number of birds presenting in the transect square within the time duration of 1 minute. Birds observed were located in the grass, trees or in the air flying over head.

Birds were identified with Tory Person's field guide, "Field Guide to Birds of North America". The birds were identified based on their color, markings, size and which bird specieis were found to be most abundant in southern Ontario according to the field guide. 

The Danby woodlot site was abundant with plant life, skies over head were slightly clear with some clouds, temperature was roughly 15 degrees celsius and windspeed calculated with the Beaufort Scale.

本实验旨在测定约克大学丹比林地（York University Danby woodlot）区域内鸟类物种的丰度。本次实验的流程为将10米×10米的带状样方（belt transect square）布设至约克大学丹比林地的10个不同采样点，其中林地区域设置5个重复样方，草地区域设置5个重复样方。鸟类丰度通过在1分钟观测时长内，计数并识别带状样方范围内出现的鸟类个体数量来估算，观测到的鸟类可能栖息于草丛、树木，或是在头顶上空飞行。

鸟类的识别参考由托里·珀森（Tory Person）所著的《北美鸟类野外指南》（"Field Guide to Birds of North America"），识别依据包括鸟类的体色、斑纹、体型，以及该野外指南中提及的安大略省南部最为常见的优势鸟类物种。

丹比林地区域植被繁茂，当日头顶天空多云偶晴，气温约为15摄氏度，风速采用博福特风力等级（Beaufort Scale）进行估算。
