Black robin breeding data

Breeding data (breeding pair IDs, kinship, location of nest in UTMs, distance to nearest neighbor's nest, number of offspring) for Chatham Island black robins, as used in analyses by Weiser et al. (Evolution). Data were collected in three wild subpopulations (Mangere Island, and Woolshed Bush and Top Bush on Rangatira Island) in 1990-2001. The file shows one line per clutch; some breeding pairs had multiple clutches in some years. Female and male IDs are the numbers from the first metal bands applied to each parent, and can be cross-referenced with the "individual data" file from this publication. "Independent young" are those that reach nutritional independence from parents, after fledging from the nest and being fed on the parents' territory for a month or two.该数据集为查塔姆群岛黑知更鸟（Chatham Island black robin）的繁殖相关数据，已被Weiser等人在《进化（Evolution）》期刊的分析研究中使用，数据涵盖繁殖对ID、亲缘关系、巢穴的通用横轴墨卡托坐标（UTM）、最近邻巢穴间距以及后代数量。数据采集于1990年至2001年间，涵盖三个野生亚种群，分别为：芒格雷岛（Mangere Island），以及兰加蒂拉岛（Rangatira Island）上的羊毛棚灌丛（Woolshed Bush）与顶部灌丛（Top Bush）。本文件以每一行对应一窝卵的格式存储；部分繁殖对在部分年份可产下多窝卵。雌雄个体的ID为首次为对应亲本佩戴金属环志时的编号，可与本出版物附带的"个体数据"文件进行交叉参照。"独立幼鸟"指的是从巢穴离巢后，在亲本领地内接受亲代抚育一至两个月，最终获得营养独立的幼体。
