Students wearing colorful costumes perfo

Students wearing colorful costumes perform during a street dance competition as part of the Birds and Eggs festival (locally known as Ibon and Ebon festival) in the town of Candaba, Pampanga province north of Manila on February 5, 2010. The festival is held to coincide with the migration of thousands of birds flocking to the town's swamp to breed. The Candaba swamps -- covered in reeds and water hyacinths and bisected by high earthen levees -- are a key staging ground for birds ranging from huge purple herons to tiny Arctic warblers that return to continental Asia in the spring.
