Canaries and finches in one aviary

Cage size is the single most important factor when keeping birds — most commercially available cages are far too small for birds to extend their wings fully, which is a genuine welfare issue, not just a comfort one. Bar spacing matters just as much: too wide and birds can trap their heads. Before I point you toward the right aviary setup for five birds, I need to know: what size are your canaries and finches specifically, do you need the partition to be permanent or removable, and how much floor space do you have available for the aviary?

Good — zebra finches and canaries are actually well matched in size, which makes bar spacing straightforward. Both need bar spacing no wider than 12–14mm, and both need enough horizontal length to fly back and forth rather than just hop. With 150cm of width to play with, you're in a strong position. Are you happy with a freestanding floor aviary, or do you need something that sits on a surface or a stand?

That narrows it down nicely. For five small finch-type birds with a permanent partition, I'd recommend the Rainforest Cages Bali Bird Aviary. It's 150cm wide, 50cm deep, and 180cm tall — your space fits it almost exactly — and it comes with a full-height internal divider that separates the space into two equal sections. Bar spacing is 12mm, which is correct for both canaries and zebra finches. The double-door system on each section is the key feature for you: it has an antechamber entry so you can open the outer door, step in, and close it before opening the inner door, which eliminates escape risk entirely during cleaning and feeding. It's powder-coated steel, holds up to cleaning well, and the removable base trays on each side make daily maintenance quick. It's available on Amazon UK and typically ships within a few days.

It's a fair concern but in practice canaries and zebra finches tolerate each other well as neighbours. Canaries can be territorial with other canaries, which is actually why your three-and-two split across two sections works in your favour — keeping the canaries together and the finches together matches their natural social groupings. They'll be aware of each other through the partition but it rarely causes stress. What to watch for in the first week or two is whether any individual bird is spending all its time pressed against the divider in an agitated way — if that happens, a visual barrier like a piece of card on that section of the partition usually settles it quickly. But most people find they adapt without any issue.

Great choice — it's one of the few aviaries at that price point that actually gets the bar spacing and double-door entry right. Make sure you position it away from direct windows to avoid temperature swings, and give each section a mix of horizontal perches at different heights so all five birds can exercise properly. Enjoy the new setup.
