Capistrano employs love songs to woo absent swallows

Maybe a good love song will bring the celebrated swallows back to San Juan Capistrano. For centuries the birds have flown the coop every October to a winter in Argentina before returning in March to the sound of ringing bells at the historic mission. The tiny birds have all but vanished in recent years as urban sprawl encroached on their nests in the southern California town. The mission, established by Franciscan missionaries in 1776, aims to woo them back with romantic music pumped from speakers tucked into its gardens during the mating season.
