, Animal Behaviour: Birds - Winner - A snowy owl comes in to land - beautiful in its symmetry. Vincent has always been captivated by snowy owls, and in north Quebec, Canada, he fulfilled his dream of spending time with them. 'I've usually had to photograph European birds from hides,' says Vincent, 'so it was a surprise to find the owls were unperturbed by my presence and I could move freely in the open'. This year-old youngster became a favourite. 'Sitting in the snow from dawn till dusk, I got to know its character.' The soft grey-blue sky provided the ideal backdrop to show off its 'sheer perfection'. Nikon D200 with 300mm f2.8 AFS lens; 1/4000 sec at f4.5; 200 ISO; tripod.
