Winter’s Early Birds
By Cynthia Berger
IN ONTARIO’S ALGONQUIN Provincial Park, February is a lean time for songbirds. The air is frosty, and lakes are lidded with ice. In a month or so, warm weather will bring out swarms of insects, but for now, food is scarce. Yet February is the start of breeding season for gray jays. Within a few weeks, on well-hidden nests, the females will sit on their clutches—three or four pale green, speckled eggs—while snow piles up all around.
