Pain, not so much not so little

The tower of Babel

What say the birds
Birds whistle, chatter, cackle, scream or howl. But what do they say? Words of love. And these words seduce both females and juries of singing competitions. The canaricultor Gabriel de la Paz explains what notes produce Harz Roller canaries and how birds are selected for competitions. The songs are tailored to the physical characteristics of […]
