Yes. To survive in the winter, most of the times they're relying on what we call a cache. And so it's like this stored up mass of sticks that they will plug into the floor of the stream or pond or whatever water source they're on. And this is just this raft of sticks that they have piled up and are in the bottom of the water source there. And so that is their primary food during the winter.
