Eurasian pygmy owl
Glaucidium passerinum

— Where the name comes from
Glaucidium is a diminutive of glaux, the Greeks’ little owl, Athena’s bird with the pale eyes: “owlet”. Passerinum adds that it is the size of a sparrow, and that is no exaggeration: at sixteen centimetres it is the smallest owl in Europe. The same idea returns in the German name, Sperlingskauz, the “sparrow owl”.

— What sets it apart
In winter it keeps a larder. In tree holes and nest boxes it stores whole prey — voles, shrews, small birds — which the frost keeps as a freezer would: dozens have been counted in a single larder, sometimes more than a hundred. That is how it gets through the weeks when snow makes hunting impossible. Its two false eyes are for daytime: the small birds that spot it and gather round to drive it off cannot tell which way it is looking.
