Results from a linear mixed effects model examining predictors of nest sizes of blue tits (Cyanistes caeruleus) in Wytham woods, Oxfordshire, including year, compartment and female identity. This analysis was run on a subset of data where females bred more than once in the study period (n = 230 nests and 105 females). This model had an R² of 0.63.
