The relationship between the timing of breeding (lay date) for successful nests in the urban subset only and nest type (nest box versus other) in interaction with temperature and rainfall pc2 (estimate 0.28± 0.09 SE, χ2(n = 159) = 9.46, P = 0.002) [negative values: High average and high min temperatures with high precipitation (total sum of rain and rain intensity); positive values: Low temperatures and low precipitation (i.e., cold and dry)] during the egg-laying period based on predicted values of LMM, 95% CIs in shaded grey.
