The saltmarsh sparrow is disappearing from its home on the East Coast
The saltmarsh sparrow (Ammodramus caudacutus) is disappearing from its home on the East Coast and could be headed for extinction, say scientists whose work could help protect the little birds. The sparrows, which weigh about half an ounce, live in coastal areas from Maine to Virginia during the breeding season and migrate farther south in the winter. Researchers with a group of universities have been tracking them for several years and reported this month that eight out of every 10 of the birds has disappeared in the past 15 years.
