Caique feather colors changing on wings

Postby cooperquinn » Thu Jul 19, 2018 11:20 pm

Hello all, this is my 1st post. I've had my little White Bellied Caique for about 15 years. We bought him when he was still an egg! He has been very healthy or so I thought, very active, glossy feathers, good appetite, etc. Within the past 3 weeks, has started to grow new feathers on his wings that are bright yellow, patches of them, and I can't find any info on why this is happening and I'm getting worried that it might be a symptom of an illness. Could anybody please tell us if they have had a similar experience and what causes it? We are 50 miles from the nearest avian vet but will go if we need to.

Hi, and welcome to the forum! Just as an FYI, I have a black-capped caique myself. Now, green feathers that turn yellow happen when the feather loses the structure that gives it a blue color. See, the thing with green feathers is that, in reality, they are not green per se, they are 'tinted' with a yellow pigment but made to look green by having a special structure that reflects only blue light so the combination of the yellow pigment plus the blue-reflecting structure makes them look green [cool, isn't it?}. Ergo, when a green feather turns yellow what happened was that the structure of the feather has been compromised in some way.

I have a male senegal that plucks himself and, whenever he allows a formerly often plucked feather to grow back, it comes out yellow because the frequent plucking damaged the follicle [the root that 'grows' the feather]. Now, which feathers are the ones that are coming out yellow now? The contours, the secondaries or the remiges?

I've seen yellow on tops of lots of caiques. Seems to be normal.

Yes, yellow is normal on them but not on the wings, those are supposed to be a solid, bright emerald green -at least the contours...

Yes, they do get yellow edges on their rectrices but I think [I am not sure because Javi has been in soft molt until recently so he hasn't had a full molt with me, yet] this is because the integrity of the feather is compromised from the rubbing of the edges against whatever so they 'lose' the blue-reflecting capability and show the yellow color given by a pigment. But the OP was asking about yellow feathers on his bird's wings which are not supposed to have any yellow on them.
