I spent the day this time taking video of the Chipmunk from the bird hide using a 400mm lens and Canon 5dmkii with magic lantern installed for greater video function.
It approached very close to the bird hide (about half a metre away) and was not phased by us at all. During the video it was digging around and found a walnut buried by an Ezo Squirrel. It couldn't get to the nut inside so after some time abandoned it. Later on the Ezo Squirrel returned and found its nut uncovered.... Both did not pay any attention to each other.
