Male bowerbirds use human trash to seduce mates

To a female bowerbird, a pile of human refuse can look like a masterpiece of romantic architecture. Male bowerbirds are famous for building elaborate stick tunnels called bowers, which serve as stages for complex mating rituals. While rural birds traditionally decorate these stages with modest seeds, leaves, and berries, urban populations in Queensland have shifted toward a more industrial aesthetic. They scavenge through trash bins and garages to find vibrant, high-contrast items that make their displays pop.
