This female Eastern Bluebird is in a classic cold weather pose. To conserve energy and retain warmth, birds fluff up their feathers, draw their head in or tuck it under a wing, and shiver. They may scrunch down by bending their legs, or tuck one foot up under their feathers to further reduce heat loss.

You cannot begin to preserve any species of animal unless you preserve the habitat in which it dwells. Disturb or destroy that habitat and you will exterminate the species as surely as if you had shot it. So conservation means that you have to preserve forest and grassland, river and lake, even the sea itself. This is vital not only for the preservation of animal life generally, but for the future existence of man himself—a point that seems to escape many people.
