Nest dimensions for cup-shaped nests of Acanthagenys rufogularis and Manorina flavigula.

Statistics include the mean ± 95% confidence interval, the F-ratio (∧) for parametric tests or Chi-square statistic/X2 (#) for non-parametric tests, as well as the P-value.*Indicates that there is a significant difference between the dimensions for each species (α = 0.05).N = 8 for Acanthagenys rufogularis and N = 7 for Manorina flavigula except nest mass and density which has N = 3 and 7 (respectively). DF = 1,13 for all parametric comparisons except nest mass and density which has DF = 1,8. Non-parametric comparisons have a DF = 1. The replicate for the nest mass and density measurements is lower as some nests were excluded from analysis due to the attachment of supporting branches.Surface area (Ā) is the geometric mean of the internal (AI) and external (AE) surface areas.
