Since I have had that feeder up, I have seen quite a variety of birds, from Black Cap Chickadees and Tufted Titmice to Cardinals and Blue Jays, and even large black crows. And, before you ask, no, I didn't take any pictures. Trying to take pictures through the screen does not work out very well.
Just now, my wife said that there were squirrels out there. Yep, they just love the bird feed. They shovel it in their mouths with both their front paws. Doesn't take them long to finish off a pile of bird feed. I went out and ran them off. They didn't want to go and I actually had to take a few quick steps toward them. I guess they don't remember getting plinked with my BB pistol. I know it didn't hurt them, so I guess they are just laughing at the stupid human trying to scare them off with a toy gun. Maybe they forgot that this human just loves the taste of squirrel. . .
OK, now don't let your day go to the birds, but have a great day, you hear?
