How it works

This one minute video explains what this birdfeeder is, how it works and what the birds do to get what they want. The feeder in the video is over ten years old. They last longer if the squirrels are kept off.

Birds are intelligent

It comes down to this: A seed in a feeder is worth two in the bush. They take the path of least resistance. They use this because it is easier.

Here a Nuthatch anticipates a seed before the feeder actually dispenses it (the wheel is gently turning counter clockwise). It watches and listens for the seed before it slides down the spout.

There was no way of knowing whether the birds would actually use such a thing when it was invented. There are so many other places for birds to find food. Apparently this is easier.

How smart varies

It was not known if the birds had the brains or the patience to make this feeder work. Certainly when they start out, they don't know what they're doing. However, it does not take much movement for it to release a seed and the birds catch on fast. Finches, Chickadees, Titmice, Cardinals, Rose Breasted Gross Beaks, Doves, Wrens, Indigo Buntings, various woodpeckers, and Nuthatches all engage.

Each spieces has a different approach to turning the wheel. House Finches and Nuthatches tend to turn the wheel in one direction. Light weight birds such as Chickadees and Gold Finches go back and forth, causing a rocking motion.

The picture above shows a Nuthatch riding the wheel counter-clockwise The wheel turns only when it is off-balance. Two birds of equal weight opposite each other on the wheel make a stalemate.
