Vowel Owl (Roger)

"OO-ih, oo-oooo!"
"OO-ih, oo-oooo!"
Something is missing from the sound
Outside the window, in the frost.
"OO-ih, oo-oooo!"
"OO-ih, oo-oooo!"
All the "oo's" are very round
But somehow all the "t's" got lost.
Poor Roger knows how poets wrote
That owls are always singing out
"Too-whit, Too-whoo, a merry note"
He does his best, beyond a doubt.
(Roger is really good as gold.)
But unlike other owls,
He only howls in vowels

Perhaps he has a cold.
