Watch free video Staying warm this winter

This video was taken near where I live at a recreational park at Bald Hills. It was mid afternoon and the sun was getting low and losing its warmth. By the lake shore I saw two parent swans standing guard on five cygnets (baby swans). The five little fluff balls were huddled together each sharing their body warmth to shield them from the late afternoon chill.
From this video I submitted a photograph for the ABC Science "Winter Warmers" photography competition and it won the people's choice award for Queensland.
