† indicates birds which should be housed alone (each pair in its own enclosure) for successful breeding to take place (this is not a concern if you do not plan to breed).
‡ indicates birds which are aggressive towards each other, and so should be limited to only one pair per mixed aviary.
Tier 1 – Passive
These birds are generally docile and can usually be kept with other birds within this tier. As always, observe the birds to make sure they are getting along.

White-backed Munia †
Tier 2 – Pushy
These birds may be housed together in a large enclosure with visual barriers, but watch them to make sure they are not unduly harassing each other. Shaft-tail Finches may be suitable companions for some of the birds from Tier 1 as well.
Dark Firefinch ‡
Green Singing Finch ‡
Lavender Finch † ‡
Orange-winged Pytilia † ‡ (do not mix with Melba Finches)
Purple Grenadier (do not mix with Cordon Bleus or Violet Eared Waxbills)
Shaft-tail Finch (Long-tailed or Heck’s Grassfinch) – (do not mix with Parsons or Masked Grassfinch)
Tier 3 – Aggressive
These birds need a very spacious enclosure with plenty of visual barriers in order to be housed together. Keep a close eye on them and separate birds that quarrel. *Note that the Java Finch is a peaceful bird that may be housed with birds from Tier 2 and possibly Tier 1, but is placed in Tier 3 because of its intimidating size and ability to coexist with the other birds in Tier 3.
Cutthroat Finch (do not mix with waxbills)
Diamond Firetail Finch (do not mix with other Australian finches)
Gray Singing Finch ‡
Java Sparrow/Finch (see *Note above)
Melba Finch ‡ (do not mix with other Pytilias, or finches with red masks [e.g. Star Finches])
Finches which are generally not suited for a mixed aviary include: Bar-breasted Firefinches, Crimson Finches, Cuban Melodious Finches, Parson Finches, Peter’s Twinspots, Red-headed Finches, and Violet Eared Waxbills.
