I have an anecdote that sounds like it fits this...

The house I used to live in had a ton of blue tailed skinks around it. You could always spot a baby by its size and brightness of the blue in its tail (juveniles have a brighter hue, adults are more brown). To avoid birds, the skinks would do this shimmy under the siding of the house just across from my back porch. What surprised me is that even the babies, maybe a few days old, all knew how to do the siding shimmy. Young, old, didn't matter, you could tell they just knew how (and why) to do it.
