Abstract

This dataset contains morphological measurements (body mass, wing length) of birds captured as part of a long-term demographic study (1977-2024) in Parque Nacional Soberanía located in Central Panama. Birds were captured using mist-nets in the understory of mature secondary forest. We also include temperature and precipitation data from the Smithsonian Tropical Research Institute (STRI) Physical Monitoring Program’s Barro Colorado Island weather station (Paton 2019, STRI). Annual dry and wet season start and end dates were determined by the Panama Canal Authority (1954-2019, Meteorological and Hydrological Branch of the Panama Canal Authority).
