Description
Lara Howard and co-authors tracked African crowned eagles living in a city-forest mix in Durban, South Africa, in a 2026 study. Crowned eagles are top hunters that breed at oddly high numbers in this city. Green corridors of protected land thread through the built areas. The team fitted five eagles with trackers that log position and body movement.
Eagles chose forest over built land when both were on offer. Their energy use rose in built areas and grew as they moved away from the green network's edge. The pattern suggests city form shapes the cost of daily life for these birds. The authors stress that protected green networks help top predators persist in cities. Urban planners can use such findings to keep habitat links intact.
