Wonky winter brings Arctic birds south, sparks early migration
North America's wonky winter forced its different bird populations to flock much farther afield this year as Arctic species moved south and southern watefowl showed up in ice-free Canada much earlier in the year.
Snowy owls from the Arctic and tundra swans, which normally winter in the southern U.S., as far south as Florida, were among the birds reported in unusually high numbers in Canada during this year's annual Great Backyard Bird Count.
Four times as many snowy owls and nearly 17 times more tundra swans were reported by Canadian participants this year than last year, said Bird Studies Canada this week.
The group partners with the U.S.-based Cornell Lab of Ornithology and the National Audubon Society of the U.S. to coordinate the annual count, which ran across Canada and the U.S. from Feb. 17 to 20.

“The call of the American goldfinch.” Carolyn Cimino, a birder from Connecticut, complimented Cronenweth: “You have very good hearing.” Guided bird walks such as Cronenweth's are common this time of year as migratory birds swoop back north for the
