You have to sign up in advance (which is why I’m telling you now) to participate in the 115th annual Christmas Bird Count but it’s free to do so this year.  The count starts December 14 and goes until January 5th.  Individual counts, however, are held in local areas on a specific day within the 3+ week period. Find your local circle and date of that bird count and/or sign up here.And, let us know what you see in the comments!
