I found these lyrics (and the musical chording to play the song yourself) on this site under tab 1 files: http://homepage.ntlworld.com/john.masterman/QY100/QY100.htm

All you little birds better lock up tight
'Coz there's a foul owl on the prowl tonight.
Hey, little lark, get out of the dark.
Foul owl on the prowl.
Cute little jay, stay out of his way.
Foul owl on the prowl.
You just might be the quail that he'll tail.
Foul owl on the prowl.
You just might be the swaller he'll foller.
Foul owl on the prowl.
If you hear him hoot, scoot.
If you pass his tree, flee.
If you catch his eye, fly.
Don't wait to say 'goodbye'.
He's got a yen for a purty little hen.
Foul owl on the prowl.
He's hungry for a chick, so get home quick.
Foul owl on the prowl.
Foul owl on the prowl.
Foul owl on the prowl.
Foul owl on the prowl.
Foul owl on the prowl.
