Can you see two clues that tell you it's a cold day in the early spring? You know it's a cold day because the robin is puffing up its feathers to stay warm. See the robin's round, puff-ball shape. You know it's early spring because no buds or leaves are on the trees yet. Photo Elizabeth Howard This Season Teachers Kids Orientation Registration Search Copyright 1997-2008 Journey North.
