As illustration for the Explanatory and etymological dictionary of Dutch birdnames by Klaas J. Eigenhuis, Dirk Moerbeek made 26 etchings for a bird alphabet.

Each etching humoristicly depicts a bird exploring and exploiting 'his' initial, as birds use to do when they are confronted with an object in their environment.

You'll find the etchings under menu option Gallery.
