GPS tracking of young Goshawks in lowland England reveals the movements and habitat use of this species, how these characteristics differ between the sexes, and how they change over the birds’ early lives. The UK Goshawk population is recovering from near extinction due to persecution in the early 20th century. Today, there are thought to be around 1,200 breeding pairs across the country, distributed patchily and at a low density. The population is likely below carrying capacity given the numbers present in neighbouring European countries, where the species is found in a variety of habitats including in cities. In the UK, the Goshawk is largely confined to forest habitats, but since the population is predicted to rise, this could change. An understanding of the movements and habitat requirements of this species could therefore help to understand how the species distribution might change in future. In this study, 29 GPS-GSM tags were fitted to Goshawk chicks at 22 nests in Breckland (Norfolk and Suffolk) and Gloucestershire. These solar powered tracking devices downloaded their data via the mobile phone network, revealing the young birds’ movements once they fledged and started to become independent. The results showed that young birds in their first winter settled on the periphery of their parents’ breeding habitat, and occupied a small range of approximately 5 km in diameter. These home ranges tended to be associated with mixed, open habitats by forest edges with farmland, or on farmland entirely. Male birds especially favoured farmland habitats. These habitat differences between the sexes might be determined by the prey types that smaller male birds can take, with suitable prey more available on farmland. As the young Goshawks matured, their habitats shifted towards the denser forests associated with their parents. The relatively short dispersal distances covered by young birds in this study indicates that a range expansion out of the species’ forest strongholds might take some time. However, young birds’ ability to take advantage of non-forest habitats does suggest that expansion is highly probable, especially if combined with a continued reduction in persecution and access to key prey.

A full voluntary transition from lead to non-lead shotgun ammunition by 2025 only resulted in a slight, non-significant downward trend in the proportion of Pheasants killed using lead shot over the five-year transition period.

Long-term studies offer valuable ecological insights but are vulnerable to change. Environmental, social and geopolitical changes bring risks and opportunities. Poland's Białowieża Forest has seen decades of changes and provides lessons of research resilience. Collaborative teams and leadership dispersed between institutes disperses the risk, and adaptability in exploiting opportunities aids the continuity of long-term studies.
