Millions of salmon spawn each year at Kuril Lake in the southern part of the Kamchatka Peninsula, Russia, attracting large numbers of brown bears.
Marco noticed how curious these two brown bears were and was able to capture the moment when they both stood up on their hind legs to watch what he was doing. The rain falling onto the lake added an extra atmosphere to the scene.
