The Great Backyard Bird Count (GBBC), which started off as an experiment, has transformed into a massive global event and now is in its 20th edition.

The first ever GBBC was held in 1998 and since then as years passed by, the event has garnered massive following with people joining in to help out by spotting birds in their backyards, parks, nature centers, on hiking trails, school grounds, balconies, and beaches. The event is all about bird watches counting birds in these locations they see for at least 15 minutes on one or more days of the count, then enter their checklists at birdcount.org. All the data contribute to a snapshot of bird distribution and help scientists see changes over the past 20 years.

Back in 1998, bird watchers submitted about 13,500 checklists from the United States and Canada. Nearly 20 years down the line, just last year an estimated 163,763 participants from more than 100 countries submitted 162,052 bird checklists reporting 5,689 species–more than half the known bird species in the world.

The GBBC is being described by experts and scientists as an annual event that helps people to get to know these winged creatures. People participation makes the event all the more exciting and provides us with a sort of instantaneous snapshot of global bird populations.

Varying weather conditions so far this winter are producing a few trends that GBBC participants can watch for during the count. eBird reports show many more waterfowl and kingfishers remaining further north than usual because they are finding open water. If that changes, these birds could move southward.

Also noted are higher than usual numbers of Bohemian Waxwings in the Pacific Northwest and northern Rocky Mountains. And while some winter finches have been spotted in the East, such as Red Crossbills, Common Redpolls, Evening Grosbeaks, and a few Pine Grosbeaks, there seem to be no big irruptions so far. A few eye-catching Snowy Owls have been reported in the northern half of the United States.

Jon McCracken, Bird Studies Canada’s National Program Director, reminds participants in Canada and the U.S. to keep watch for snowies. He says, “The GBBC has done a terrific job of tracking irruptions of Snowy Owls southward over the past several years. We can’t predict what winter 2017 will bring, because Snowy Owl populations are so closely tied to unpredictable ‘cycles’ of lemmings in the Arctic. These cycles occur at intervals between two and six years. Nevertheless, there are already reports of Snowy Owls as far south as Virginia.”

In addition to counting birds, the GBBC photo contest has also been a hit with participants since it was introduced in 2006. Since then, tens of thousands of stunning images have been submitted. For the 20th anniversary of the GBBC, the public is invited to vote for their favorite top photo from each of the past 11 years in a special album they will find on the GBBC website home page. Voting takes place during the four days of the GBBC.

The GBBC is a joint project of the Cornell Lab of Ornithology and the National Audubon Society with partner Bird Studies Canada and is made possible in part by sponsor Wild Birds Unlimited.
