Owls?

Yes, there are a lot (and I mean A LOT) of drawings, paintings, prints of owls out there.  Owls are expressive, easy to draw and cute, cute, cute. They have an image of nocturnal bird who is wise and thoughtful. They eat mice, but so what? Mice are rodents. But sometimes owls are friends with some exceptional, intelligent and courteous mice.

if you look carefully it says "sweden and norway" and "valkyrie's song" on top of the page, it was a total accident or not :)
