Parrotlet

Yes. These "pocket parrots" are only around 12–13cm long but often have a personality as big as any large parrot, and can be nippy or territorial, especially without early, consistent socialisation.

Much quieter than most parrot species, which makes them a popular choice for apartments. They're still capable of chirping and calling, just without the piercing volume of a conure or cockatoo.

A pellet-based diet with fresh vegetables and a small-seed blend.

Feather Chef Lovebird Blend ($15.99–$89.99) is formulated for lovebirds and parrotlets specifically, and Vetafarm Nutriblend Mini Pellet ($15.99–$124.99) is a palatable mini pellet option.

A single parrotlet bonds closely to its owner and needs daily interaction to stay content. A pair will keep each other company, but unlike lovebirds, parrotlets can sometimes squabble with a same-sex companion, so introductions are best done gradually in neutral space.

Smaller than a standard parrot cage, but with narrow bar spacing given how small they are. A Small Bird Bath ($10.99) is a nice, appropriately sized addition, parrotlets are among the species it's designed for.
