We've had lots of ice and even more snow on top of that, so far this winter. That makes it especially hard on all the wild creatures to survive here in Bluff Country. I do feed the birds with black oil sunflower seeds, mixed nuts, plenty of suet and the cheapo big box variety of mixed seed which gets tossed on the ground as well. There are two platform feeders, a prized green and yellow "John Deere" hanging one and another hanging variety that closes automatically when a squirrel, racoon or other large creature climbs on the perch. The amount of food being consumed each day has increased exponentially.
The large hole in an oak tree in the back yard (our house is surrounded by oak and white pine) is inhabited by a large family of squirrels. Although they are exercised daily by my large GSD, they still manage to spend much time grazing contentedly on sunflower seeds. I had for a few years tried various stratagems, other than armed violence, to deter them . Greasing the poles upon which the platform feeders sat was only one of the unsuccessful stratagems . The following video will demonstrate why I gave up on the deterence plan.
Oh and I forget to mention, of late a herd of deer have been joining the feast, and more importantly arousing the kenneled dog. Since he can't chase after them, he attempts to deter their intrusion upon his territory by insane barking, usually about 2 a.m. in the morning. Our human neighbors are all nice people but I'm getting worried about phone calls. Grrrrr.
