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.
