Yellow-Bellied Marmot

Marmots are usually seen basking in the sun on a large rock or roadside. Never far from their rocky dens, they lumber quickly to cover at any sign of dangers. Lookouts, usually perched on a nearby rock, emit a loud, sharp whistle when trouble is near. Marmots are the largest member of the squirrel family. In early fall, they retreat to their dens to hibernate, re-emerging in the melting snows of March.
