Chickadee-dee-dee-dee in the Deep Freeze

MP

Published in the The Fitzhugh, December 3, 2014 Imagine going to bed, and waking up having lost 30 per cent of your body weight. For some it may seem like an appealing weight loss plan, but for the hearty black-capped chickadee, this nightly weight loss comes from spending huge amounts of energy to stay warm during winter nights when they are unable to feed. This is the research of Magali Petit, a PhD candidate at Université du Québec à Rimouski. Petit is interested in understanding…

Jasper Fitzhugh  August 06, 2014 When the wind blows through my Jasper cul-de-sac, the spruce trees brace themselves against the gusts, the way millions of years of evolution have designed them to. This year, however, the tops of some of the spruce are so laden with cones, it seems possible that with one good blast, they might just snap off.
