Flutter Butter

Think this one was peanut flavour or mealworm flavour. It's been out all summer and remains untouched by bird or beak. I don't think they recognised it as a source of food and I couldn't think how to get them interested.
Don't birds have a sense of smell ?
They were all over the bird feeder next to it.
Such a shame this hasn't been bothered with. I have two others to put out.
