Best Macaw Cages UK: Large Parrot Cages and Aviaries
Short answer: a macaw needs a strong, wide cage with bar spacing of about 2.5 cm, heavy-gauge wire (around 4–5 mm on serious large cages) and enough room to stretch both wings and climb without the tail touching the bars. Width matters more than height. Start at around 100–120 cm wide for a large macaw and go bigger if your room allows. Even a big cage is a base rather than a full-time home, so plan for daily supervised time out of it too.
This page is our shortlist of the large cages and aviaries we sell that are described for macaws, with the measurements from each product page. For sizing in more depth, read what size cage a macaw needs.

What makes a good macaw cage?
Width and footprint
Macaws are long-tailed, heavy-bodied birds. A tall, narrow cage forces them to climb up and down instead of moving sideways and stretching out. Look at the internal width and depth, not just the outside size. Your macaw should be able to open both wings fully without touching the sides, and turn on its perch without its tail hitting the bars or the floor grille.
Bar spacing
Bar spacing has to stop the head passing through the bars. For large macaws, about 2.5 cm is the usual starting point; our bird cage size guide puts large birds at 2.5 cm or more. Smaller macaws, such as mini macaws, may suit slightly closer bars. Check the figure against your own bird and the manufacturer’s guidance. If your bird can fit its head between the bars, the cage isn’t right for it.
Wire strength and build
A macaw’s beak can bend light wire and pick at weak welds. On large cages, look for wire of around 4–5 mm, solid welds, and locks that a clever beak can’t lift. Most of the large Rainforest cages in our range list 5 mm wire.
Doors, trays and cleaning
Large front doors make it easier to get your bird in and out and to fit perches and toys. Pull-out trays, a floor grille and seed catchers keep mess down. Castors help you clean behind the cage, but only on a level floor.
Room and delivery access
Large cages often come on a pallet. Measure your doorways, stair turns and the space the finished cage will take up, including seed-catcher overhang, before you order. Check the delivery options shown on each product page.
Our macaw cage shortlist
Rainforest Rio Ara: the all-round macaw cage
The Rainforest Rio Ara is built for large parrots such as macaws. It measures 102 × 76 × 186 cm, or 122 × 96 × 186 cm with the seed catchers fitted, and has 2.5 cm bar spacing and 5 mm wire. It comes with a 100 cm internal perch and four 15 cm bowls, and it fits Cage Cover Size 6 (sold separately). It’s a good fit for one large macaw in a normal living room.
Rainforest Parrot Double (Antique): two long perches
The Rainforest Parrot Double measures 100 × 76 × 190 cm, with 2.5 cm bars and 5 mm wire. It includes two 102 cm perches and four 13 cm bowls, so there’s room to set perches at different heights from the start.
Rainforest Castello II: extra width and a divider
The Rainforest Castello II is approx. 162 × 81 × 185 cm, the widest cage on this list (the aviaries apart). It has a removable divider, seed catchers, pull-out trays and castors. The divider lets you house two birds or separate one during introductions; take it out and one macaw gets the whole interior. Its product page doesn’t give a bar-spacing figure, so check this with us before you order.
Liberta Endeavor: wide and dividable
The Liberta Endeavor is a wide, dividable large-parrot cage with 5 mm wire, a seed catcher, a pull-out tray, castors and four stainless-steel bowls. Its bars are 2 cm apart, closer than the 2.5 cm we’d usually look for on a large macaw. That suits smaller macaws and large parrots with smaller heads, but check it against your own bird.
Rainforest Nova 2 Aviary: an indoor aviary
If you have the room, the Rainforest Nova 2 Stone Aviary gives a macaw far more space. It measures 206 × 101 × 220 cm (internal 205 × 100 × 200 cm), with 2.5 cm bars and 5 mm wire. Its removable divider splits it into two 102 × 100 × 200 cm sections. It comes with two 102 cm perches and four 15 cm bowls.
Rainforest Parrot Aviary: the most space
The Rainforest Parrot Aviary is 219 × 158 × 210 cm (internal 214 × 153 × 200 cm), with 2.5 cm bars and 5 mm wire. It includes three 13 cm bowls and works with the Parrot Aviary Base (sold separately). It’s the closest thing in our range to a room of its own for a macaw.
Rainforest Santos Play: for smaller macaws
The Rainforest Santos Play (Stone) is 92 × 71 × 168 cm outside, but 89 × 69 × 120 cm inside, with 2.5 cm bars and 5 mm wire. The play top adds two 91 cm perches and two bowls for time out of the cage. Its interior is too small for a large macaw to live in full time, so treat it as an option for smaller macaws. A Santos Dome version is also available.
Setting up a macaw cage
- Perches: use natural wood perches of different diameters, thick enough that the toes don’t wrap all the way round. Set them so the tail stays clear of bowls and the floor.
- Toys: choose large, macaw-rated chew toys and rotate them. Read our bird-safe rope guide before adding rope.
- Bowls: stainless-steel bowls, with food and water kept apart and away from perches above.
- Placement: put the cage against a wall in a room the family uses, away from draughts, kitchens and direct sun.
- Checks: inspect the bars, welds, locks and castors every week. A macaw will find a weak point.
Macaw cage FAQs
What size cage does a macaw need?
Start at around 100–120 cm wide for a large macaw, with enough depth and height to stretch both wings and climb without the tail touching the bars. Bigger is better. See our macaw cage size guide for detail.
What bar spacing is right for a macaw?
About 2.5 cm for large macaws, with heavy-gauge wire. Smaller macaws may suit slightly closer bars. Your bird must not be able to fit its head through the bars.
Can a macaw live in an African Grey cage?
Usually not. Grey cages are often narrower, with lighter wire. A large macaw needs more width and stronger bars. Some medium-to-large cages, such as the Santos, list both, but check the internal size against your macaw.
Is an aviary better than a cage for a macaw?
If you have the room, yes. An indoor aviary like the Nova 2 gives far more space to move. Your macaw still needs daily time out and attention either way.
How do I get a large cage into my house?
Measure doors, hallways and stair turns before you order, and check the delivery options on the product page. Large cages usually arrive flat-packed or part-assembled on a pallet.
