I was attacked by Mr Kadlcák, who wrote to me on an ordinary postcard and said that the bird was a jay and certainly no nutcracker, which was a mistranslation of the German Eichelhdher.
Kadltxak jaunak gutun arrunt batean eraso zidan, txori hura eskinoso bat zela eta ez intxaur-jalea, eta Eichelhäher hitzaren itzulpena zela.
