Influence of prey availability on habitat selection during the non-breeding period in a resident bird of prey

Table 2 Resource selection function for used and available focal areas within the non-breeding home ranges of barn owls

Fixed effects	β mean (95%CrI)
Intercept	− 13.07 (− 13.17 to − 12.96)
Sex m	− 0.20 (− 0.30 to − 0.08)
Small mammal activity density/focal area	0.15 (0.08 to 0.21)
Vole activity density/focal area	0.18 (0.08 to 0.29)
Biodiversity structures (present)	0.13 (− 0.04 to 0.30)
Small mammal activity density/focal area × Biodiv. structures	− 0.39 (− 0.47 to − 0.32)
Vole activity density/focal area × Biodiv. structures	0.21 (0.15 to 0.28)

Random effects	Variance (± SD)
Deployment (Intercept)	0.13 (± 0.39)
Small mammal activity density/focal area (slope)	0.04 (± 0.20)
Vole activity density/focal area (slope)	0.14 (± 0.38)
Biodiversity structures (slope)	0.48 (± 0.69)

We present the mean estimates of β and associated 95% credible interval of the posterior distribution of a logistic mixed effect model based on 65 individuals. Sex, vole activity density per focal area, small mammal activity density per focal area, and biodiversity structures were introduced as explanatory variables, tag deployment as random intercept, and vole activity density per focal area, small mammal activity density per focal area and biodiversity structures as random slopes. Vole and small mammal activity density per focal area was modelled in interaction with biodiversity structures
Effects whose credible interval does not include 0 are shown in bold
