Hi Folks,
Good day to you.
Need some advice below...
1) May i know which species of Cordon Bleu is a better singer?
Blue-Cap Cordon Bleu vs Red Cheeked Cordon Bleu which sings better?
i have looked at some you tube videos it seems to me Blue-Cap Cordon Bleu sings better.
but i am not too sure if this is the real case...
2) Comparing Cordon Bleu vs Gouldian finch, which is a better singer?
3) i am also looking at Java sparrow. how does his singing compare to Cordon Bleu and Gouldian finch
Currently i keep 2 finches each in his own cage.
Green singer male and Strawberry male. both are pretty looking finches and good decent singers.

Thanks for your help and advice.

I have always liked the Java's song, as well as that of the common canary.
But as most on here are breeders not single bird in a cage for singing types, don;t know if many actually think about that aspect of their birds.

Hi thanks for advice
Yes agreed, i see some youtube videos, Java sparrow seems to have decent singing ability.
and Java seems much better singer than Cordon Bleu or Gouldian according to those youtube videos.
Actually i am looking for finches with decent singing ability plus some good colors.
Thanks
