The phenomena you are thinking of is not visible light, like colors we perceive as "bright". It's the reflection of UV light....and this has more to do with the material properties and brighteners than any specific color. Cotton glows and so do a lot of synthetic materials, especially when washed with brighteners.
Colors are just different wavelengths, and so is UV. We see colors because the pigments absorb all the other wavelengths and reflect the ones we can perceive with the Cones in our eyes....and this absorption/reflection depends on the properties of the object in question.
Now, some feathers are actually designed to reflect UV light like reflective tape and a flashlight. This is because birds can see very well in both color and UV wavelengths, and use these patches of UV-reflective feathers for mating rituals, communication, etc.
Here's what a Saw-whet Owl wing looks like to us:
And to other birds:
I know that natural turkey wings do not reflect UV at all. However, I wouldn't be surprised if some of the artificial barred feather materials do reflect UV.....quick search found these images.

Hope that helps,
