Birds of prey face a variety of human-induced threats. Migratory birds of prey are particularly at risk to these threats due to the often long and arduous annual journeys from their breeding grounds to wintering areas and back. Moreover, some species either migrate in large groups or form major concentrations along their flyways and require adequate networks of suitable habitat along their migration paths. These include, for example, narrow land bridges, sea crossings, mountain passes and coastlines, where they are especially prone to intensive hunting and trapping and which enhance the potential impact of some threats.
According to a UK study
the most significant threats derive from intensive land use practices that reduce prey availability and suitable breeding habitat. However, other factors alone or in combination also negatively affect raptors under various circumstances, such as:
Electrocution by overhead power-lines
Collision with power and other aerial infrastructure
Illegal poisoning (intentional and unintentional)
