While I asked myself this question, it was not really one I wanted to spend much time answering. So, below is what ChatGPT suggested.
1. Wilson’s Bird-of-Paradise

2. Gouldian Finch

3. Painted Bunting

4. Resplendent Quetzal

5. Lilac-breasted Roller

6. Mandarin Duck

7. Scarlet Macaw
This one is overrated, in my opinion. Colorful? Yes. Stylish? Definitely not.

8. Violet-backed Starling
The inclusion of this one is a bit of a mystery to me, as the species basically only has two colors. If the list of colorful birds were prepared by FIFA and the Violet-backed Starling was a US bird, I could see a clearer rationale.

9. Indian Peafowl

10. Rainbow Lorikeet

I was surprised to realize that I have already seen half of these species, and shocked that no pitta made it into the list. I guess AI still has some way to go.

The violet-backed starling is a jewel. Deserves its place on the list.
Not bad, 5 out of 10.
Seems the color of Violet is special. In China, purple is the color of royalty, and the Forbidden City is literally “Purple Forbidden City”. And in the fashion world, this is probably the most difficult color, “If you can wear purple well, you can wear anything.”
What, no kingfishers? No bee-eaters? A curious selection.
Euria gave the following list : Scarlet Macaw, Rainbow Bee-eater, Hooded Merganser, Northern Cardinal, Blue-and-Gold Macaw, Peacock, the Eurasian Kingfisher, any Toucan, Ruby-throated Hummingbird, any Bird of Paradise. Good list and addressing some of the omissions. Of course, AI will never mention pittas, Kai, as AI invented pittas in the first place.
