The Snowy Egret wears a silky white wedding gown with a long lace train and pledges his troth with a twig. She does, too - and it's a double twig ceremony. But who can tell the bride from the groom? They can, and a few weeks later they're taking turns at babysitting, keeping their love alive by swapping twigs at nest - relief. The Snowy's recovery from near-annihilation by plume hunters is one of our country's happiest examples of conservation in action.
