Two important pieces of the natural history are the timing of reproduction and morphometrics. In this study, we estimate the reproductive season of Antioquia Brushfinch (Atlapetes blancae) based on a large database of observations and captures. We also provide the most extensive morphometric data base of males, females and subadult individuals for this species. Taking advantage of ecological modelling techniques, we estimated that the reproductive season of A. blancae most likely spans from February through late July with peak reproductive activity during early July. The reproductive activity is influenced by day length and precipitation. We also found that subadults are smaller than adults and females are smaller than males providing evidence for both, age and sexual size dimorphism. This study is the first attempt to provide important missing information about A. blancae that could help with understanding of population viability.
