Thanks for the sunflower information. Nice song too. BTW, what does курлычут mean? I couldn't find the word in the dictionary and Google translate didn't know it either. I did find a phrase with another form of the verb:
курлычет кошка на заборе
but I'm not too sure what cats and cranes have in common and so the meaning of
Журавли курлычут где-то,
evades me!
