Marmots Love to Play | Bob Armstrong's Nature Alaska

This video demonstrates some of the ways in which marmots play.
In, at least Southeast Alaska, the Hoary Marmot resides along some of our saltwater beaches and in the alpine.
Both the beach and alpine marmots play a lot.
This video was taken along a beach in the Juneau area.
The group probably involves both parents, one youngster from last year (a teenager) and one first year marmot.
The one laying down is probably the adult male (dad) because they do not normally take care of the children.
I suspect the largest one standing is the adult female (mom).
