Tracking Peregrine Falcons

In September, a streamlined Peregrine Falcon calls as it wings its way south from its Arctic nesting grounds. The pale gray falcon will spend the winter in Chile.

Wimbledon Peregrines

Wimbledon is legendary: the verdant green of the courts, the throngs of fans in sun hats, sightings of royalty ... and lots of pigeons.
