The Effect of Pest Species on Other Birds

This experiment took place throughout several days (October 13th, 14th, 16th, 17th, 18th and 19th in the year 2020), all the chosen locations were Ponds in Vaughan Ontario. The goal of this experiment was to observe the effect that Pest species have on the diversity and frequency of other birds in the same location (i.e, observable from staying in one spot). Behaviour, species,frequency and approximate distance from other species (in meters) were all factors taken into account. In suburban areas such as Vaughan, it is often seen to have a clear separation between pest species (most frequently Canadian Geese in this case) and other species. Therefore, this experiment used quantitative and qualitative values to determine how true this statement is. All observed values took place in the morning (between 8 A.M and 10 A.M) and the researcher spent 60 mins at each location. The weather varied from 5° C to 15° C and from clear skies (the 14th and 17th) cloud cover (13th, 18th and 19th) and occasionally rain (the 16th).

本实验于2020年10月13、14、16、17、18及19日历时多日开展，所有选定观测点位均为加拿大安大略省沃恩市（Vaughan）的池塘。本实验旨在探究有害物种（Pest species）对同一观测点位（即固定点位下可观测范围内）内其他鸟类的多样性与出现频率的影响。观测指标涵盖鸟类行为、物种类别、出现频率，以及与其他物种的近似距离（单位：米）。在沃恩市这类郊区区域，通常可见有害物种与其他鸟类存在清晰的生境分隔，本次实验中以加拿大黑雁（Canadian Geese）为最常见的有害物种。因此本实验通过定量与定性结合的分析方法，验证该观测论断的准确性。所有观测均于每日上午8时至10时之间开展，研究者在每个点位停留60分钟。实验期间气温介于5℃至15℃之间，天气状况涵盖晴好（10月14日、17日）、多云（10月13日、18日、19日），偶有降雨（10月16日）。
