What is the prettiest bird?

A Swan.

I agree. Swans are beautiful and graceful.

Parrot

I like the Robin birds.

Doves are a very pretty bird and also represent peace:).

Egrets are pretty cool. I saw one on tv last week in China that an old man had tamed. He loved it like a pet dog. It ruled the house and didnt like the mans wife. He rode a bike with the egret sitting on the handle bars.
I live in Australia and my garden is full of these parrots.

American Bold Eagle.

I think the prettiest bird is a scarlet Ibis.

I like flamingos because I think that it is cool that the shrimp they eat is what gives them their pink coloring.
