By Erin Fuchs, Chattanooga Times/Free Press, Tenn.

By Lucas van Grinsven AMSTERDAM (Reuters) - Blue-collar workers in Europe and the United States who feel threatened by Asian rivals should spare a thought for local birds, crabs and oysters, also facing competition from more efficient eastern species. Dull-colored pigeons, starlings and crows used to dominate the skies above Amsterdam, but these days citizens might spot the brilliant green plumage of a long-tailed tropical parakeet. Originally from Asia, 1,200 collar parakeets now...

The first...
