Nature Done Wright

On Monday I asked:

This item is about a half-foot long, and pictured sideways here so it fits the blog better.

It will come in handy for certain critters in the next month, and they only use it once.

What is it?

The correct answer: A ladder from inside a Wood Duck nest box. the ducklings climb the ladder soon after hatching to greet the world.

Thanks to all who answered correctly!
