Top ranked generalized linear regression models for sex ratios (for Akaike model weights [<i>w</i>_<i>i</i>] > 0.1) based on no time-lag (<i>t</i>), a two-year time-lag (<i>t</i>– 2), and a three-year time-lag (<i>t</i>—3).

Models were ranked based on differences in AIC corrected for small sample size (ΔAICc), weights and evidence ratios (ER). Climate variable abbreviations can be found in the text or S1 Table.
