A Book of Various Owls

A Book of Various Owls by John Hollander and illustrated by Tomi Ungerer is a vintage children's poem book.

Here is one:

Prowl Owl (Jack)

You usually hear him across a lake

Like the moan of a distant loon,

But then, in a moment, his shadow will break

The white face of the moon.

Before he's really left the sky

You hear him blow his beak

Under a nearby pine. His cry

Plays games of hide and seek.

Wherever you think his shadow may be

It's hidden behind your back:

Jack lurks about, too dark to see

When the green of the trees is black.
