It's cherry season, so I cut a few up and put the pieces into the traditional Tasty Snack Dish, and put it into the Finsterium.

It turns out that they're Evil. Pure, Unadulterated Evil. So Evil, in fact, that no Finster ventured to the floor the whole time the dish sat there. So Evil, in fact, that no Finster even ventured onto the lower perch. So, after about ten minutes of Finster Torture, I took the dish out. After another ten minutes or so of Making Sure The Evil Cherry Things Wouldn't Show Up Again And Leap Up To Hit Suspicious Birds On Their Heads, the Finsters finally ventured down for breakfast.

I wasn't going to let those cherry bits go to waste, so — since they were untouched by Finster beaks — I started eating them with a spoon. Peanut came over to help. He decided that the cherry bits were best for flicking into the sink, but that the cherry juice was good for drinking.

So I was surprised when I saw him staring down at his food dish later that day from the safety of his sun porch, which is a good six inches higher than the dish. He spent a little more than a minute on that sun porch, twisting his head so one eye was looking straight down into the dish. Finally, he slowly climbed down and perched on the dish, still looking at the quarter of an Evil Cherry I had put inside. He stared at it, one-eyed, for about a minute, and finally moved his head about a half an inch further into the dish. Then he stared at the Evil Cherry again for a minute. Slowly, he moved his head about a half an inch further into the dish. Then he stared at the Evil Cherry again. He must have spent close to five minutes staring the Evil Cherry into submission before he finally reached down, grabbed the offending fruit with his beak, and flicked it across the cage. Evil.

Turns out that blueberries are Evil, too. But I could have guessed that. They're...round, after all. And...blue. Evil.
