How do I safely introduce a new second bird to my current one?

I'm thinking of getting a second bird to keep my current one company. But I've heard introductions can go badly. What's the safe, proper way to introduce two birds so they (hopefully) get along?

QUARANTINE FIRST — minimum 30–45 days, separate room, ideally a vet check on the newcomer. New birds can carry diseases that don't show immediately. Skipping quarantine is how people accidentally infect a healthy bird. After that, slow introductions.

After quarantine: separate cages in the same room so they see each other, then neutral-territory out-of-cage time, supervised. Never just put a new bird into the resident bird's cage — that's the resident's territory and it can turn aggressive fast.

Smart to research first — rushed introductions are how they go wrong. The safe sequence:

1. Quarantine the newcomer first — a separate room (different air space ideally) for 30–45 days, with an avian-vet new-bird check. Birds can carry diseases that aren't visible early; this protects your current bird.
2. Visual introduction: after quarantine, place their separate cages in the same room, a comfortable distance apart, so they can see and hear each other for several days.
3. Neutral territory: supervised out-of-cage time in a space that isn't either bird's cage — never put the new bird straight into the resident's cage (that triggers territorial aggression).
4. Go slow & watch body language: brief, positive sessions; separate at any real aggression and try again later. Some birds bond fast, others coexist as 'neighbours' — and that's okay.
5. Keep separate cages available even if they get along.
