This week’s cold and snow will likely kill off many of the birds that stayed around for Ottawa’s warm autumn, a leading birder says.
“There are a lot of late lingering birds still around,” said birder Bruce Di Labio. On Monday he photographed a black-throated grey warbler — a little songbird that somehow took a wrong turn from its home in the southwestern United States. It should have flown south, and now it’s too late.
“I was able to get about four feet from it,” Di Labio said. “It just sat there a foot above the ground, tight against this little tree. You could see it shivering and then it just closed its eyes in the sunlight, obviously trying to heat up.
