Smaller birds have looser skin while larger birds have tighter skin.If
you have tight skin it's like a wetsuit.It keeps your body heat enclosed
for a longer period of time.The looser skin lets the body heat escape
easily. If you are a bigger bird you have a tendency to have more body
fat to keep you warm. A smaller bird is thinner so the heat can leave
quicker while the bigger birds are wider so they can keep the heat in
longer.
