Inter-annual variation in the number of hawk territories in Dadia-Lefkimi-Soufli National Park fitting Generalised Additive Models. Population trend modelling is also shown for each species with cubic regression (cr) or cyclic cubic regression (cc) splines used as smoothing terms, depending on lowest AIC in each case.a Variation in the number of Northern goshawk territories fitting a GAM b Predictive GAM for the Northern goshawk with smoothed terms (cc splines) c Variation in the number of Eurasian sparrowhawk territories fitting a GAM d Predictive GAM for the Eurasian sparrowhawk with smoothed terms (cr splines) e Variation in the number of Levant sparrowhawk territories fitting a GAM f Predictive GAM for the Levant sparrowhawk with smoothed terms (cr splines).
