Table 2.

Analysis of deviance table for the minimal model of a GLM with quasipoisson errors (log link function), with Richness in adult blue tits as the dependent variable

Term	Degrees of freedom	Relationship	Deviance	F	P
Date Sampled	1	Negative	1.25	4.24	0.0497
1st egg date	1	Negative	5.00	16.92	0.0003
Clutch size	1	Negative	4.86	16.44	0.0004
Family	23		29.68	4.37	0.0002

The main effects in the maximal model were Year, Wood, Family, Sex, Date Sampled, Hour Sampled, Mass, Wing Length, 1st Egg Date, Clutch Size, and percentage of Nestlings Fledged. Null deviance = 40.35, Null df = 52, Residual deviance = 7.77, Residual df = 26.
