Roots & a Robin in Regent's Park

On Friday i cycled up to Regent's park, in the snow, searching for roots. A helpful arboricultural officer that i'd e-mailed had told me about a tree that had recently fallen down, so i found some good ones.
A little robin hopped about really close to me, completely unafraid - looking for bugs and worms, i guess, though i don't think he found many in the snow...
