Mine don't have a face...but the slit can be anywhere on the bottle as long as you have it facing so the wind will blow across it. Mine can be turned, so if the wind is blowing from a different direction I turn mine a little until they start singing to me again.

They have been out there for two summers now, and not many a day has gone by without hearing their sound. I absolutely love them.

But if they did have a face it would be the nose...a loooong nose....lol

Mine each have a different length nose...which gives them each a different sound. They harmonize...

Oh...and the slit is about a half inch wide

Thanks so much for that info Pattico. I am off this weekend to make a couple now that I know where the slit goes and how it works. Thanks for the info on the sizes of the slits too.
