Last November, the Audubon Society broadcast a live TV documentary via satellite to 1000 schools in the United States and the United Kingdom. It featured John Takekawa, a wildlife biologist with the U.S. Geological Survey (USGS) as he fitted 10 snow geese in New Mexico with satellite radios as part of a 5-year research program on migration.

Now students are taking to the Internet to follow the geese. Every other day during the 5-month trip (February through June), the birds' radios send signals to National Oceanic and Atmospheric Administration weather satellites. These signals are bounced to stations in France and Maryland, which determine the birds' positions within a few tens of kilometers. The results are e-mailed to the USGS in Davis, California and posted on the Audubon Web site. The site also has a field journal, updated three times a week by Takekawa, which describes the birds' rest stops and meals, gives weather updates, and offers geographic and cultural information about the areas the birds fly over. "More of our geese are headed for Nebraska! It looks like TT and TP are joining TZ," wrote Takekawa on 11 March. "Peak migration in Montana is near the end of March, so we should see big movements in the next 2 weeks."
