Do not buy a second bird to fix a problem
A second bird will not automatically solve screaming, biting, boredom, or loneliness. It adds another personality, another care routine, and another safety plan.

Bird behavior
A second bird is a relationship, not a shortcut.
Some birds thrive with bird companionship, some do not, and some pair so strongly that human handling changes. Introductions need time, separate space, and supervision.

A second bird will not automatically solve screaming, biting, boredom, or loneliness. It adds another personality, another care routine, and another safety plan.
A new bird needs separation before introductions, not an immediate cage share. A practical starting point is at least 30 days of separate housing with avian-vet guidance, separate bowls and tools, and careful observation before shared space. Wash hands between birds and avoid sharing perches, toys, carriers, or cleaning tools during the separation period.
Start with distance. Reward calm looking, relaxed posture, and easy redirection. Do not force birds onto the same stand or into the same cage.
Chasing, pinning, blocking food, guarding a person, beak fencing, foot grabbing, or one bird trying to escape are signs to separate and slow down.
A bird that bonds to another bird may want less handling from people, or may guard a person more strongly. That is not betrayal. Adjust expectations and keep routines kind.
Blood, repeated chasing, exhaustion, food blocking, injury, severe fear, or sudden aggression means the birds need space and a better plan.
Use supplies as structure, not shortcuts. The goal is to make calm choices easier for the bird.

Only after careful introductions and only if the birds are compatible, healthy, and safe together. Many birds should keep separate cages.
The relationship may change. Some birds become more bird-focused, some become jealous, and some balance both.
