Thanks! So because of your cool photo, today I learned that the German word for wren, Zaunkönig, means "fence king."
Nice! Many old names for common birds have that same delightful folksy observational quality. (In contrast to birds named for a naturalist who encountered them). "Fenceking" joins my life list of gems like "honeydipper," "turnstone," "flycatcher," & of course "goatsucker."
Not that our old friend the shoebill finds all this amusing.
