Anyone wanting to feed birds has a problem with squirrels. But it seems to me that evolution solved that problem long ago (since squirrels nest in trees, and so do many birds), and all we really need do is pay attention.

Many "herbivorous" mammals will deign to eat high- quality protein when it is available. Squirrels are considered to be rodents, and I think we all know that rats eat eggs. So what do birds do about that?

I think, but am not sure, that the parent birds will sit on eggs until the insides become more bird-like than yolk- like. This may be enough to deter squirrels. In a bird feeder, this would translate as a kind of automatic "bird" that would peck at intruding squirrels. I dunno if this is the answer. It may only be an answer....

Some birds are carnivorous; many rodents are omnivorous scavengers, of which rats are a prime example - squirrels are no more than bushy-tailed tree rats.

It could power itself by gradually metabolising the food in the bird-feeder. If the bird feeder is not kept well topped up, this device may lash out in annoyance at passing humans.
