Abstract
Going, Going, Gone: Is Animal Migration Disappearing
Highlights
Animal migration surely ranks as one of nature’s most visible and widespread phenomena
Birdwatchers in North America and Europe, for example, complain that fewer songbirds are returning each spring from their winter quarters in Latin America and Africa, respectively
A recent continent-wide analysis of European breeding birds concluded that longdistance migrants have suffered sustained and often severe population declines, more so than related nonmigratory species [1]
Summary
Animal migration surely ranks as one of nature’s most visible and widespread phenomena. More than 30,000 tons of migratory songbirds migrate from their wintering grounds in Latin America and the Caribbean to their breeding grounds in the United States and Canada.
