Every autumn in Guanajuato, Mexico, the city celebrates the Festival Internacional Cervantino, or El Cervantino, as it is known to many. The event began in the mid-20th century as a festival of theater performances—short plays called entreméses, mostly those written by Spanish novelist and playwright Cervantes. But in the 1970s, the festival expanded to include many additional arts, music, and cultural performances from around the world. This photo captures a performance by a group called Studio Festi.
Fall sets in motion a journey of some 3,000 miles for these monarch butterflies, which migrate from southern Canada to their wintering habitat in central Mexico. There, they cluster together in fir trees, creating the illusion of orange, fluttering foliage. They’ll remain in their winter roosts until March, when the journey back north begins. But no one individual monarch will complete the full round trip, which exceeds the normal monarch life span; instead it will take four generations of monarchs to complete the full migration, each individual seemingly driven by an internal compass that guides its flight path.
