Today's Geo Quiz is for the birds. The Great Backyard Bird Count gets under way this weekend. Thousands of people across the US and Canada plan to pitch in. The idea is to report on what's on view in your backyard wherever that may be. The data helps produce online maps showing which species are on the move, and where others are flocking.
Take the Common Redpoll. This bird occasionally shows up at backyard feeders across the northern US but its main habitat is the wide band of northern forest that spans Canada.
That forest extends from Newfoundland and Labrador all the way to the far northern Yukon. So what's the name of this Canadian forest that lies mostly above 50 degrees north?
The answer is Canada's boreal or "northern" forest. It spans the country from the Yukon Territory to Newfoundland and Labrador. It's also habitat to hundreds of bird species including the Common Redpole, one of the many species that is expected to show up in this weekend's Great Backyard Bird Count. Anchor Lisa Mullins speaks with Miyoko Chu of the Cornell Lab of Ornithology who explains why counting birds such as the Common Redpole and the Bar-tailed Godwit is important to scientists.
