Does Juicedaw mean anything or have a connection to something in the game?

I've seen it on a spell (Ulm's Juicedaw Feather) and the Juicedaw Feather Ring

There's a kind of crow called a Jackdaw, and in old times it used to just be called a 'Daw'. Since 'Juicedaw' is related to Feather magic I'm guessing that's the connection, and that a Juicedaw is a Tamrielic bird of some kind.

The Juicedaw Feather Ring is needed in one Fighters Guild quest, but other than that, they don't have any real significance.

maybe these feather spells were created by the great mage Juicedaw.....but having that name would be rather funny....

No, the wizard that invented the spell would be Ulm. And Ondusi would be the one who invented open spells.
