(Studio) Chesapeake Bay may face environmental problem created by creature almost universally loved.
REPORTER: Walter Cronkite
(Saint Michaels, MD) Fairy tale, "The Ugly Duckling", by Hans Christian Andersen, noted. Problem for Bay area is mute swans who live there. Though these swans multiply rapidly and run off geese and ducks from what they consider their territory, major problem is that they eat a lot; mute swans aren't native to area, but those escaped found it and flourished; stay here all year Biologists' concern is damage to underwater grasses if swans continue to proliferate. [Environment William BAKER - says problem arises when swans eat underdeveloped vegetation. Notes they are sometimes forced to eat grasses in early stages.] Grasses are fndtn. of Bay life, for all marsh creatures depend on it, include humans who harvest living from Bay. May sound strange to those who grew up with Tchaikovsky's music and Andersen's fairy tale, but future cry around Bay may be to beware of the swans.
