Table 1. Results of initial LMM models testing for effect of lightness (ranging from 0—black to 100—white) on egg volume and laying order of 331 eggs of 66 nests.

Nest box and year were used as random effects. The variables retained in the final models are indicated by boldface.

Lightness	Df	F	B ± SE	P
Egg volume	1,326.93	5.38	−0.001 ± 0.000	0.021
Laying order	2,326.93	243.49		<0.0001
