Data from: Revisiting Fisher: range size drives the correlation between variability and abundance of British bird eggs

Data_DRYADDatabase containing raw data used for the analyses conducted in the study. Data regarding migratory status was obtained from the BTO website as well as for wing length (www.bto.org/birdfacts). We used total breeding population size estimates from Baker et al. (2006) and geographic range as the number of occupied 10 x 10 km squares following Sharrock (1976). Original egg measurements were obtained from Fisher (1937).
