A national park along South Africa’s southern coast protects key breeding grounds for more than a dozen seabird species. But dangers remain. On Bird Island in Algoa Bay, puddled water from heavy rains makes a messy landing for a Cape gannet. Climate change models pre- dict more frequent and intense rainfall in the region, and flood- ing can cause large- scale loss of eggs. An altered climate can affect other birds by moving their fish prey farther from their breeding grounds. NEXT PHOTO After hitting the water at 60 miles an hour, plunge-diving Cape gannets feast on high-calorie sardines, their preferred prey. This photograph cap- tures the first evidence (top right) of under- water kleptoparasitism among Cape gannets: one bird caught heist- ing a fish from another.
