In the associated data paper, we present an open-access database of bird morphology, reproductive condition, and molt phenology for 379 bird species of the Colombian Tropical Andes, one of the regions with the highest bird diversity on Earth. This database contains information from both museum specimens (1969–2014) and captures in the field (2008–2019), from 52 localities. This morphological and reproductive information, along with the occurrence records, will encourage new research lines on bird ecology. These photographs illustrate the article “A morphological, reproductive, and molt phenology database for 379 bird species from the Colombian Tropical Andes” by Cardona-Salazar et al. published in Ecology. https://doi.org/10.1002/ecy.3016
