Quakers have banded tails?

[zERo]

I just found one of Tony’s tail feathers and saw it has faint bands on the entire underside.
I broke out his feather bag and saw that all of his tail feathers are this way.
These aren’t stress bars or bronzing so they’re just barring?
They aren’t on the short tail feathers, only the longer ones.

That’s utterly fascinating! I’ve never seen such a thing before. I looked it up and it’s apparently froth bars!

I had long believed that horizontal bands are sourced to Stress and have seen them referred to as Stress stripes or Stress bands. I have not seen anything new /current, but have not specifically looked either.

The last I saw it was with Parrots entering as part of the Import facilities years ago.

Likely causes now a days can be diet transition (starvation fear), New Home /New Family, etc..

Have not seen anything that would define their development to growth as the feather grows within its cover over a short period of time and there would be great variation and not the precise pattern commonly seen.

He used to have really pronounced stress bars, as did my GCC before their firsts molts with me.
I wasn’t sure if these were too as they look really different to me.

Yeah, I wasn’t aware of them either! But now we both (and others who read it) do know! Also, you can find images of them on safari, google, bing, etc. and they also look identical to your quake’s feathers! The more ya know!
