If you're not familiar with CBCs, they are all day bird counts in a given area. That could be a town (East Brunswick), a county (Sussex), or any other location you can think up (the Raritan River Estuary). The events this year run from December 14th until January 5th, and you can still get in on many that invite the public or decide to have your own just for fun!
The Christmas Bird Count is a great way to get outdoors during the winter season and have a good time. It's also a great way to serve as a citizen scientists; the data gathered during these events may help conservation organizations to determine the health and status of many groups of birds.
