Raptors in a changing world: Understanding the response of predators to increasing urbanisation

597 597 people viewed this event.

Urban development is increasing across the globe and poses a major threat to biodiversity, which is often relatively low in human-modified landscapes. More people live in urban than in rural areas globally, and the urbanization trend is faster in Africa and Asia than in any other region of the world. Avian predators are amongst the most vulnerable species to urbanization, but a few have persisted, thus contributing substantially to functional diversity in urban habitats.

To date, the majority of urban raptor research has occurred in North America and Europe, but findings from one region may not necessarily translate to populations of the same or similar species across regions. This scarcity of research is despite the fact that Africa hosts its own unique assemblage of raptor species many of which face substantial conservation challenges. Urban areas might create valuable opportunities for public engagement and urban conservation. In this talk I will focus on the responses of raptors to increasing urbanization, providing examples from across the globe and highlighting urban raptor research from Africa. My own research has used long-term data of individually colour-ringed populations to better understand the key resources which attract raptors to urbanized areas, and explores how the decision to settle in urbanized areas can affect individual health, productivity and survival.
