| Summary: | The relationship between the timing of breeding (lay period) and (a) the urban gradient (estimate -0.34 ± 0.07 SE, χ 2 (n = 399) = 23.31, P < 0.001); (b) temperature and rainfall pc1 (estimate -0.11 ± 0.05 SE, χ 2 (n = 188) = 5.69, P = 0.017) [negative values: cold and wet weather conditions; positive values: warm and dry weather conditions]; (c) temperature and rainfall pc2 (estimate -0.13 ± 0.06 SE, χ 2 (n = 188) = 5.20, P = 0.023) [negative values: warm and wet weather conditions; positive values: cold and dry weather conditions]; and, (d) nest type (nest box versus other, urban subset with urban gradient >40% urban cover; estimate -0.41 ± 0.20 SE, χ 2 (n = 188) = 4.33, P = 0.037) during the egg-laying period based on predicted values of LMM, 95% CIs in shaded grey.
