He looks cold.
I thought for a moment you meant to post in G&N 
I wondered if anyone would make that connection and I didn't have to wait long it seems 

resRe: A Beaver In Febrary (2)
That has to be a fairly young one. A mature will go 30# plus with a rare few getting around 60#. Great capture. Rick
PS The more I look at this one, are you sure he had a flat tail? The tail seems way to small for a beaver. It appears more the size of a muskrat to me. Muskrats are much more active during the day where as beavers are late evening and morning workers. Also, a beaver tail can be as long as 18" by 12" wide. When they slap the water with their tails as warnings to other beavers, it sounds like a blooming tree falling in. These are fantastic shots. Very clear.
Thanks Res and I can assure you this is indeed a beaver...my best guess would be around 40lbs. A second one did slap the water and this one quickly got into the river. I thought they were going to meet but the one doing the slapping instead took this one's place and brought its own stick to chew on. I am attaching another shot here in a larger format and I think you will be able to see the flat tale clearly as well as the teeth. They do have a similar look to muskrat and its hard to gage the size in the photos so I understand your wondering if I got the ID right. Here is that other shot.
And a big thanks to Steve, and Momtothefurmonsters as well as Likwid. Lord Brian and Chris for looking and commenting
