Fifth Annual Great Backyard Bird Count
How will this winter's snow and cold temperatures influence bird populations?
Where are the winter finches and other irruptive species?
Will late winter movements of many songbird and waterfowl species be as far north as they were last year?
Help Cornell and National Audubon scientists answer these and other questions by taking part in this year's Great Backyard Bird Count. Everyone's contribution is important. The data you collect will be combined with Christmas Bird Count and Project FeederWatch data to give an immense picture of our winter birds. Anyone with an interest in birds, from novice to expert, can be part of GBBC by tallying numbers and kinds of birds they see in their backyards, schoolyards, local parks or any favorite birding location for as little as 15 minutes a day on any or all of the four count days.
This year's count marks the 5th anniversary of this immensely popular event. Over the years, more than 100,000 citizen scientists throughout the United States and Canada have submitted reports which have helped researchers track winter finch invasions, investigate the correlation between snow cover and northerly distributions of American robins, and document the "arrival of spring" by following movements of blackbirds as they begin their migration s back to their breeding grounds.
Visit the GBBC website, www.birdsource.org/gbbc for instructions and results from previous counts. At the site, you can also listen to bird songs, see bird images, and learn about species of conservation concern. Material for classrooms, tips for bird feeding, and a how-to for creating bird-friendly yards are also at the site.
