Brain size and migration distance in birds

This table contain data on 1,475 globally distributed bird species. Data covers: brain mass (g), body mass (g), minimum body mass (g), maximum body mass (g), migration distance (km), non-breeding range minimum monthly mean temperature (°C), breeding range temperature seasonality (°C), mean non-breeding latitude (absolute value). Additionally, coordinates of the breeding and wintering range geographic centroids (latitude and longitude), and monthly mean temperatures for both the breeding and wintering grounds are given.
