  1. P model is the p value of a general linear model with species as predictor, and the other three p values are testing pairwise differences between species (Ni nightjar, Cu cuckoo, Sw swift). p values <0.05 are in italics. p values <0.0016 (applying a Bonferroni correction) are in italic underline
