Phantom of the forest or successful citizen? Analysing how Northern Goshawks ( Accipiter gentilis) cope with the urban environment
By 2040, roughly two-thirds of humanity are expected to live in urban areas. As cities expand, humans irreversibly transform natural ecosystems, creating both opportunities and challenges for wildlife. Here, we investigate how the Northern Goshawk ( Accipiter gentilis ) is adjusting to urban environ...

By 2040, roughly two-thirds of humanity are expected to live in urban areas. As cities expand, humans irreversibly transform natural ecosystems, creating both opportunities and challenges for wildlife.

We measured a variety of behavioural and ecological parameters in three urban and four rural study sites. City life appeared related to all parameters we measured.
