Which animal stockpiles the most food?

1 BEAVER 200-2,000 kg twigs + branches. The food is hidden on lake floors, where the beaver lives. The cold water keeps the food fresh. 2 ACORN WOODPECKER 150-200 kg of acorns. Individual acorns are hidden in

cavities or in thousands of small holes in special tree trunks. 3 SQUIRREL 20-50 kg of nuts and cones. The food is placed in forest floor

deposits. If the squirrel forgets some, new trees grow up. 4 BLUE JAY 20-30 kg of nuts. Individual nuts are hidden in deposits throughout the wood, in the ground and in branches. 5 WATER VOLE 10-35 kg of potatoes and roots. The food is typically stored in an excavated burrow or in a hollow tree trunk.
