Birds have migrated north in large numbers in recent weeks — an early gamble that is now forcing some to do a U-turn, and others to starve.
A number of people in Ottawa have heard Canada geese fly over noisily, beginning in late February’s mild spell.
“Thousands of geese showing up in eastern Ontario. A lot of them are actually still here,” birder Bruce Di Labio said. But with snow covering the cornfields and freezing temperatures at night, they aren’t going any farther north.
