Table 3.

Analysis of deviance table for the minimal model of a GLM with binomial errors (log link function), with inter-annual survival of adult blue tits as the dependent variable

Factor	Degrees of freedom	Relationship	χ 2	P
Year	1	2007 > 2008	5.57	0.0183
% Nestlings Fledged	1	Positive	4.88	0.0272
Richness	1	Negative	7.08	0.0078

The main effects in the maximal model were Year, Wood, Richness, Sex, Date Sampled, Hour Sampled, Mass, Wing Length, 1st Egg Date, Clutch Size, and percentage of Nestlings Fledged. Null deviance = 73.00, Null df = 53, Residual deviance = 55.02, Residual df = 50.
