Table 3 Results of several analyses of covariance to test the effect of latitude and longitude on nest parameters for all of the nest and after it was separated into the outer nest and the cup lining

  1. The model included box area (cm2) as a covariate to control for variation in box size between locations. The parameter in each row was tested individually. Data are presented for the five largest components—analysis for other components are shown in the supplementary materials. Component masses were Log10-transformed prior to analysis. Values are F statistics, with p values in parentheses. Degrees of freedom = 1644 for each factor and covariate
