Prevalence of blood parasites (percent of
infected individuals) in Spanish diurnal birds of prey in relation to
their breeding habitat, world geographic range, and incubation period
index (I) as predicted by the GLM model. Continuous lines,
species breeding on forests; discontinuous lines, species breeding on
open or open-woodland habitats. Values for world geographic range and
I cover the variability observed in the studied species.
