Model (binomial GLMM) on nest predation risk during the incubation (n = 923) and nestling period (n = 839) in relation to different habitat structures.

Habitat structures = distance from the nest to woodland or crop edge, and field layer height (FLH) around the nest site (tall or short; reference category = short). Year and territory identity were included as crossed random effects (Incubation: variance year = 0.14, territory = <0.0001; Nestling: variance year = 0.31, territory = 0.38). Dropped non-significant interaction terms incubation stage model: FLH*house distance p = 0.85; FLH*road distance p = 0.44. Dropped non-significant interaction terms nestling stage model: FLH*woodland distance p = 0.65; FLH*crop distance p = 0.35; FLH*house distance p = 0.13; FLH*road distance p = 0.55.
