The phrase "spruce it up" has a very different meaning for beavers come Spring.
Now they may be also be attending to their appearance by grooming and re-oiling their fur but it appears from my latest visit to their pond, that these beavers have made another trip to the near by woods to harvest a few more fresh spruce tree branches. New shoots & vegetation are most likely still in short supply.
Having shared a meal, one by one they left for other venues around the pond. The photos below are of the last beaver to leave and probably stayed the longest. Although he/she appears large, this beaver was probably one of the smallest of the four who came to feast and probably was born early last Spring.
