The cavities mimic the natural tree hollows they once relied on, and with fewer old-growth trees left standing, the birds are adapting in surprising ways.

From disappearing habitats to opportunistic nesting strategies, owls are showing that survival sometimes means turning human leftovers into makeshift homes. Each reason tells us more about how these birds navigate a changing world.
