These fun clocks, originally marketed as inexpensive novelties, are now quite collectable. Westclox made a number of these. Some were made in the Hong Kong or Mexico plants with inexpensive movements and materials. The lead example, with copyrighted Woody Woodpecker graphics, was marketed under the Columbia Time imprint used by Westclox for some models.

The Early Bird was produced as an animated model for decades in a variety of case and dial styles.

The animated piece works off of an elongated pin on the pallet fork, shown here using a Westclox Pixies clock (before cleaning) for example.. This is part of the escapement that creates the "ticking" of a mechanical clock, and the animation keeps time with the ticking.

To end with something a little different, here is an electric animated clock, the Telechron powered General Electric "Trixie".
