The Cool, Rugged Lifetime of a Snow Bunting

Written by Bob Sundstrom

That is BirdNote.

Climate within the Arctic continues to be wintry when male Snow Buntings return to nesting areas in April. They’ve spent the winter roaming shorelines and fields of grain stubble — chilly, windswept locations within the northern United States and Canada.

Males attain their breeding territories on the tundra a month forward of females and defend them relentlessly.

This implies male Snow Buntings could face freezing circumstances and snow blanketing the bottom.

However there’s an enormous profit to arriving early sufficient to say a primary nest cavity in a rock face or underneath boulders, the place will probably be safer from foxes and Snowy Owls.

Nesting in chilly rock cavities means further care should be taken to maintain eggs and nestlings heat. That’s why, not like many different fowl species, feminine Snow Buntings by no means come off the nest. The males convey them meals, giving them extra steady time on the eggs. This shortens the incubation time, enhancing the chances of hatching a wholesome brood.

And all of it begins with an early — if considerably chilly — begin to the season.
