Count birds in your own backyard

Want to do a little science but not have to spend too much time on data collection? Sign up online for the annual Great Backyard Bird Count, February 18-21. The bird sightings that you collect will go into a continent-wide database and "help build critcal information on long-term trends in bird populations," says Paul Green, director of citizen science for the Audubon Society.
