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.
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 can also negatively affect raptors under various circumstances. These factors include: environmental pollution, poisoning, trophy shooting, capture and trade for falconry, collisions with and electrocution by overhead power-lines, general disturbance, and the looming threats from climate change. In addition, migratory raptors require adequate networks of suitable habitat along their migration paths, and many species tend to congregate at land-bridges, mountain passes and along coastlines where they are especially prone to intensive hunting and trapping.
