(My rambling estate)
The critters are getting ready for Winter.
As seen in the picture (taken from my bedroom window) above, Mr. Groundhog/Woodchuck (Marmota monax) on the left is pretty fat by now to get him through hibernation season, or at least until February 2nd at any rate.
Mr. Squirrel (Sciurus carolinensis, the freakin' tree rat!) on the right is gathering acorns which have fallen from the mighty red oak that drops a prodigious amount of leaves each Autumn.
This was the "on" year for that tree; oak trees only bear their nutty fruit on alternate years, but generally not until they are about 20 years old.
Soon, too soon, it will be Winter...
