Occurrence data of Chinese Galliformes

Occurrence records were mainly collected from China Bird Report Center (CBRC) and National Specimen Information Infrastructure (NSII) (China Bird Report Center, 2019; National Specimen Information Infrastructure, 2019), while some were got from eBird and GBIF (eBird, 2019; GBIF, 2019). Coordinates of records with detail locations were got through map tools, and the records of low spatial resolution were removed. All occurrences were validated by distribution range maps which were downloaded from BirdLife International to estimate and remove the outline points (BirdLife International and Handbook of the Birds of the World, 2018).

本数据集的物种出现记录主要采集自中国鸟类报告中心（China Bird Report Center, CBRC）与国家标本资源共享平台（National Specimen Information Infrastructure, NSII）（中国鸟类报告中心，2019；国家标本资源共享平台，2019），另有部分记录来源于eBird与全球生物多样性信息网络（Global Biodiversity Information Facility, GBIF）（eBird，2019；GBIF，2019）。对于带有详细地理位置的记录，通过地图工具获取其坐标信息，并剔除空间分辨率较低的记录。所有物种出现记录均通过从国际鸟盟（BirdLife International）下载的鸟类分布范围地图进行校验，以甄别并移除分布范围外的异常点（国际鸟盟与《世界鸟类手册》，2018）。
