3. SUMMARY This section summarises details on foraging distances for all species and distances between alternative nest sites for relevant species. The distances represent a summary, where possible, of all the data reviewed within this document. We feel the values presented here would be the most relevant to judging connectivity to SPAs. 3.1 Foraging ranges during breeding season Foraging distances during the breeding season are summarised for all species in Table 7. Table 7 - Summary of foraging distances during breeding season Species Red-throated diver Black-throated diver Foraging range from nest site during breeding season Generally less than 8km, but regular flights of 11-13.5km recorded on Western Isles. Likely to be less than 10km. Red kite Core range of 4km, with maximum range of up to 6km. Hen harrier Female core range of 1km, with majority of foraging within 2- 3km, and maximum range of
3.2 Foraging ranges during winter season Foraging distances during the winter are summarised in Table 8 for whooper swan, greylag goose, pink-footed goose, Greenland white-fronted goose, and barnacle goose. Table 8 - Summary of foraging distances during winter season Species Whooper swan Greylag goose Pink-footed goose Greenland white-fronted goose Barnacle goose Foraging range from night roost during winter season Core range of less than 5km. Core range of 15-20km. Core range of 15-20km. Core range of 5 – 8 km. Core range of 15km, with maximum recorded distance of up to 25km. 3.3 Distances between alternative nest sites Distances between alternative nest sites are summarised for relevant species in Table 9. 47
