Mark My Bird

The Mark My Bird dataset comprises 3D scans of bird bills from the ornithology collection of the Natural History Museum, London. Mark My Bird is part of a European Research Council (ERC) funded project based at the University of Sheffield. The project aims to contribute to our understanding of how and why bird species form and diversify. 3D scans of bills were taken primarily from the ornithological skins collections. The scans were uploaded to the markmybird.org citizen science website where they were analysed by both researchers from the University of Sheffield and volunteer citizen scientists. Analysis involved landmarking pre-defined features of the bill on computer visualisations of the scans.

The dataset comprises records of 2028 specimens. Each specimen represents a different birds species and is typically a male. The dataset includes raw scan data in obj format, landmarks from 3-4 volunteers (and the average of those landmarks) for each specimen stored as txt files with three columns of XYZ coordinates. Mark My Bird usernames, documenting the contributing volunteer, are assigned to each landmark file. The dataset also includes a csv format file (MarkMyBird_manifest.csv) detaling taxonomy, museum accession number, and sex for each species.

‘标记我的鸟类’（Mark My Bird）数据集收录了伦敦自然历史博物馆鸟类学馆藏的鸟类喙部三维扫描样本。该项目是谢菲尔德大学承担的欧洲研究理事会（European Research Council, ERC）资助项目的组成部分，旨在推动学界对鸟类物种形成与分化的机制及成因的认知。本次喙部扫描样本主要采集自鸟类剥制标本馆藏，扫描得到的样本模型被上传至markmybird.org公民科学平台，由谢菲尔德大学的研究人员与志愿公民科学家共同开展分析工作。分析工作包括在扫描样本的计算机可视化界面中标注预定义的喙部特征点。
该数据集共收录2028份标本记录，每份标本对应一个独特的鸟类物种，且通常为雄性个体。数据集包含OBJ格式的原始扫描数据，以及每份标本对应的3至4名志愿者标注的特征点（含该组特征点的平均值），相关数据以TXT文件存储，文件包含三列XYZ坐标。每份特征点标注文件均标注有该项目的志愿者用户名，以记录贡献者身份。此外，数据集还包含一份CSV格式文件（MarkMyBird_manifest.csv），详细列明了各物种的分类学信息、博物馆馆藏编号以及性别信息。
