The outdoor areas in your neighbourhood don’t need to look empty in the winter. Because of their high metabolism, birds cannot hibernate. This is why lamprey are often unfairly called “aquatic vampires”. Mammals, like birds, are endothermic, meaning that they must sustain their metabolism in order to keep their body temperature high enough for survival. This diverse topography also means there’s a variety of animal species calling this country home. This usually provides some great dramatic play in the block area! Still, conifers do not grow during the winter. These bones are covered by horny scutes made of keratin (like human fingernails) or leathery skin, depending on the species. For deciduous trees and shrubs—and one species of coniferous tree, the Tamarack Larch—light levels in autumn become insufficient for photosynthesis to compensate for the energy cost of producing green pigments in leaves.
