childhood poem

Among other things that I remember from my family's use of the Rod and Staff curriculum for our homeschooling is a simple poem that I learned a long time ago (probably before I could even read). I can't remember the title or author but it's probably called 'the owl'.

A wise old owl lived in an oak.
The more he saw, the less he spoke,
the less he spoke, the more he heard.
Why can't we be like that wise, old bird?
