Scattered bird brain? No way jay

MY local supermarket was crowded during the recent cold spell; people were building up stores of food.

Animals protect themselves against freeze-ups by putting on weight.

Hedgehogs fatten up in late autumn but this is not an option for all creatures. Red squirrels, for example, must remain slim and trim; being heavy when flitting about in thin branches at the tops of trees, is not recommended. Contrary to popular belief, however, squirrels don’t hibernate. They rely on food stores instead.
