Finch compatibility

[alf]

[Is this a properly matched pair? It's been two months since iI ntroduced the female and I haven't seen them mate yet.. i

The one with the white cheeks and black head looks like a Java to me. Can't really tell what the other one is. What are they supposed to be? Have you heard either one sing?

[wildbird]

If both birds chirp, they are females.

The one with the black head sings and does that mating dance/hop but he used to do that even when he was alone. The fawn colored Java just chirps. Thanks guys but there never was any doubt about their sex. What I was afraid of was whether they were incorrectly paired because of their different colors., or if I needed to include extra protein or something in their diet. Will try to post a close-up of the female to confirm anyway.

There you go. It's a little blurry but one can make out the beak and crest.;
