Title: Saving Migratory Birds: The Quest for Knowledge vs. the Ticking Clock Post by: Donna on 02-Sep-10, 09:10:58 AM http://nationalzoo.si.edu/scbi/migratorybirds/science_article/default.cfm?id=50 (http://nationalzoo.si.edu/scbi/migratorybirds/science_article/default.cfm?id=50)
At the end of summer each year, birds from forests across North America leave their breeding grounds and travel thousands of miles, through all kinds of weather, over mountains and oceans, to their wintering grounds in the tropics. Since it is such a long and demanding trip, they will need to stop in unfamiliar habitats to find food and rest before continuing on their journey to a tropical land that is quite different from the temperate one they left behind. In 5 to 8 months, they will start the journey again, in reverse. It happens every year, and yet we understand so little about the journey and the birds who undertake it. (Read on if you like, it's pretty long) but very interesting.

Highly recommended reading for everyone, with interesting insights, especially since our area is along an important migration highway.
