According to the Audubon Society, information from CBCs over the past century — combined with data from other surveys such as the Breeding Bird Survey in late spring — have helped researchers, wildlife agencies and others determine the long-term health and status of bird populations across North America.
Today, the data also are being used to help develop strategies to protect birds and their habitats, and help identify environmental issues that have implications for people as well.

IN THE SKY: From David Dundee, Tellus Science Museum astronomer: The Geminid meteor shower is expected to reach a peak of 50 meteors per hour tonight. Best viewing: In the northeast sky after midnight. The moon will be last-quarter on Wednesday night. Only two planets are visible now: Venus is low in the west just after dark and sets two hours later; Mars is low in the east about two hours before dawn.
