Housing Mixed Species Help to avoid hybrids

[TailFeathers]

Hello,

I'm housing mixed species in my aviary right now and I'm afraid to get fertile hybrids out of these birds. Please let me know what of the following may hybridize for fertile babies so I can remove them into separate enclosures.

Green singer finch
Grey singer finch
European goldfinch
Himalayan goldfinch
Siberian goldfinch
European Linnets
Canaries
European Greenfinch
European serin


All of these birds are babies that are mixed sex. So I would need to act soon once I can sex them.

Thanks

I only have experience with Gray Singers, so I can't say for sure how all these species will get along in your aviary, and a lot may depend on the size of the aviary. If you only have one pair of each species, you already have 18 birds, which would require a fairly good-sized aviary anyway. Of all these species, you only have two genera--Serinus and Carduelis. I would imagine that it might be difficult to keep from having fertile hybrids with so many birds sharing the same genus. Gray Singers and Green Singers can be aggressive, and the same can be said for canaries. Personally, I would be hesitant to mix any of these species at all. It will be interesting to hear from those with experience with more of these species.

All goldfinches cross with fertility.

Gray x green singers are fertile.

Unsure of the others.

canaries hybrid with almost every other member of the same family, it think with all of them on this list, I think all of them will be infertile however accept for the canary x european serin, they are fertile.

other combinations I know of:
european goldfinch x european linnet
european goldfinch x european greenfinch

Tailfeathers - all three types of your goldfinches could easily hybridize amongst each other. What would be the point of getting all three different kinds and then potentially letting them cross breed. So I would definitely separate these three kinds.
I've had canaries, European goldfinches, European linnets and European siskins (not serins, I know, but similar) in the same aviary. No aggression, no crossbreeding, but I had one pair of each so there was 'no need' to look for a non-species mate.
The only fertile hybrid I ever had (by accident!) was between a canary and a black-headed canary (alario finch). And only the females of these are fertile.
Sorry I can't help with possible cross breeding combinations of the birds you have.
