Best rust-proof bird cage for coastal outdoor use

Coastal and humid environments are brutal on standard powder-coated cages — they rust within months, and flaking rust or zinc from degraded coatings is genuinely toxic to birds. So stainless steel isn't just a preference for outdoor use near the sea, it's really the only sensible material. Before I point you in the right direction: what species and approximate size is your bird, are you housing one or more, and how much outdoor space do you have available for the cage?

African Greys are large parrots with a wingspan of around 46–52 cm each, so a standard cage is nowhere near enough for two. With that patio space, you've actually got room for something proper. Are they bonded and housed together already, or currently in separate cages?

Perfect — that makes things straightforward. For two bonded African Greys going outdoors in a coastal environment, I'd recommend the Rainforest Cages Amazonia Stainless Steel Aviary. It's constructed from 304-grade stainless steel throughout — no powder coat, no zinc, no rust risk — and the bar spacing of 25mm is correct for Greys (wide enough to grip, not wide enough to trap a head). At roughly 120cm wide by 60cm deep by 150cm tall it gives them real room to move, and the design is robust enough for permanent outdoor placement under a covered area. It's a significant investment, but it's the last cage you'll buy — stainless steel at this gauge simply doesn't degrade the way coated cages do in salt air.

A few things worth thinking through. Even under a covered patio, make sure one side of the cage always has shade — direct sun on a metal cage can raise internal temperatures dangerously fast. You'll also want to check that the cover overhead prevents driving rain from reaching them, as prolonged wet feathers cause problems. Keep the cage raised off the ground slightly to avoid pooling water underneath, and check the door latches regularly — stainless holds up well but mechanisms can seize with salt deposit over time. A quick rinse down monthly keeps it in good shape.

Good choice for those two. The stainless steel cost is front-loaded but you won't be replacing it in three years like you would a standard cage in your conditions. If you want perch recommendations for the outdoor setup — natural wood varieties they can actually chew through — that's worth thinking about alongside the cage.
