BACKGROUND
, a hummingbird distributed in the tropical Andes, has been included in Venezuela's bird list on the basis of a specimen collected in 1873 at Sierra Nevada, Mérida and deposited in the Natural History Museum, London, with no further records for this country since then. This record, largely considered as valid by most authors, has been questioned by others, although without formal analyses.
NEW INFORMATION
The potential habitat range of the Green-Tailed Trainbearer, (Trochilidae), in the northern Andes from Ecuador to Venezuela was modelled, using maximum entropy niche modelling, environmental covariates and records from locations across the Colombian Andes. The predicted suitable habitat range corresponded well to the known range of the subspecies in Colombia and clearly excluded Sierra Nevada. Therefore, these analyses suggest that this species should be removed from the Venezuelan bird list.
背景
长尾蜂鸟分布于热带安第斯山脉地区，因其1873年在梅里达州内华达山脉采集的一个标本而被列入委内瑞拉鸟类名录，该标本现存放于伦敦自然历史博物馆，自那时起委内瑞拉再无该物种的记录。大多数作者基本认为这一记录是有效的，但也有其他人对此提出质疑，不过并未进行正式分析。
新信息
利用最大熵生态位建模、环境协变量以及来自哥伦比亚安第斯山脉各地的记录，对绿尾燕尾蜂鸟（蜂鸟科）在从厄瓜多尔到委内瑞拉的安第斯山脉北部的潜在栖息地范围进行了建模。预测的适宜栖息地范围与哥伦比亚已知的该亚种范围吻合良好，且明确排除了内华达山脉。因此，这些分析表明该物种应从委内瑞拉鸟类名录中移除。
