To celebrate National Bird Day and in collaboration with Twentieth Century Fox Home Entertainment and the DVD/Blu-ray release of its comedy about birding, “The Big Year,” we have hatched a Free Bird Photo Contest! E-mail a picture you have taken of a bird in the wild by the end of the day Jan. 31, 2012, and you will be eligible for the top prize: a new pair of powerful binoculars and a bird feeder made out of recycled materials. The top 20 entries each will receive a DVD or Blu-ray copy of “The Big Year,” which stars Steve Martin, Jack Black and Owen Wilson. See the contest rules and prize details.
