Michael Warren: Trumpeter Swan
The Trumpeter Swan, larger and deeper-voiced than the more numerous Tundra Swan, apparently enjoyed a wider distribution in North America when our nation was young. Although it did not reach the Atlantic Coast, Audubon knew it well on the Ohio and Mississippi rivers, as well as in Texas. If he was correct, all that changed drastically. By the 1930s the bird was on the endangered list. Since then, under protection and management, it has made a partial comeback in the northwest and is no longer considered endangered. Today the main population exists in south and central Alaska, migrating to British Columbia and Washington for the winter. Their diet consists almost exclusively of green plant matter and seeds, with lesser quantities of aquatic invertebrates. Artwork Copyright © 1985 Unicover Corporation.
