“It looks like much of the country is getting perhaps a one- to three-week-early arrival for many species,” said Jason Berry with American Bird Conservancy.
He cautioned in a statement that should such warmth become a regular or permanent feature, it would impact many bird species.
“Some would be able to adjust, but unfortunately, many would not,” Berry said.
Birdwatchers taking part in Cornell University’s Great Backyard Bird Count in February revealed that the nearly freeze-free winter was also the most unusual for birds in the count’s 15-year history.
A total of 623 species were observed during the four-day survey, including an influx of snowy owls from the Arctic, early migrating sandhill cranes and belted kingfishers in northern areas that would have normally been frozen over at that time of year.
