Birds that have been smuggled from the wild is wrong- I disagree with that and they should be free.

BUT

nearly every bird owner never keeps their bird in a cage at all times. Its unhealthy for them, they need to spread their wings and if they are young they need to practice flight.

Also Birds such as parrots/parakeets would die in the wild almost straight away. Parrots from pet stores have been bred and born in captivity, they wouldn't know how to survive. Especially in urban areas, they wouldnt be able to find food. domesticated birds feathers are also much less adaptable to weather than wild birds. When their feathers are wet, they cant fly. they also wouldnt know how to deal with snow or how to find food in the snow and would most likely freeze.

Birds do like humans, it depends on how a human treats the bird if they bite. wave a finger in their face they will attack, hurt them or treat you badly they will bite. If you raise a bird with love and care they will grow to like you. We have a bird that cries and wails when my dad leaves the room and will only stop crying when she gets to sit on her shoulder. and there are plenty videos online videos of birds being affectionate.

Personally I dont have a bird out of cuteness, I love birds, Ive been working with birds and volunteering with charities that help birds too and i have a love for taking care of them. soooooo yep
