Ethiopia's urban hyenas double as waste workers and cultural icons

In Ethiopian cities like Harar and Mekelle, spotted hyenas and other scavengers help clean up urban waste by scavenging leftovers, reducing disposal costs and emissions, and potentially limiting disease spread. Studies show these urban hyenas process thousands of metric tons of waste annually, a mutual benefit locals largely view as positive, though attitudes vary by city. In Harar, a centuries-old hyena-feeding tradition persists inside the ancient walls and has become a tourism draw, while Mekelle’s hyenas commute nightly to landfills. Researchers caution that excessive habituation could provoke conflict, urging planners to balance ecosystems with initiatives like controlled eco-parks to sustain coexistence.

Florida crocodiles start basking on boats as habitat shifts

Researchers tracking American crocodiles in Broward County have documented them sunning on docks, kayaks, and even jet skis, a thermoregulatory behavior that arises as their natural habitat is disturbed. Sun exposure helps regulate body temperature and may influence parasite dynamics, illustrating how urbanization is pushing crocodiles to use human structures for basking to survive.

Could Raccoons Be the Next Great Pet?

Experts weigh whether any wild species could be domesticated into the next popular pet; raccoons are highlighted as a potential example, but true domestication is a slow, complex evolution driven by social behavior and interaction with humans, with many urban wildlife species potentially following a commensal path rather than deliberate breeding, and dogs and cats remaining the benchmark.

Pandemic-era beaks: UCLA juncos show rapid, reversible evolution

UCLA researchers found dark-eyed junco songbirds on campus hatched in 2021–2022 developed longer beaks, resembling mountain birds, likely in response to a more limited, campus-based diet during Covid-19 closures. After restrictions eased and students returned, birds hatched in 2023–2024 showed shorter beaks again, suggesting a rapid, reversible evolutionary pulse tied to human activity. The team is pursuing genetic data to confirm if these shape changes are genetic, and highlights how quickly wildlife can adapt to urban environments.
