White lines on new feathers?

We are getting the hang of it. I think Yoshi has it figured out better than me now, however!

His diet for the most part is pretty good. He always has Harrison's High Potency Fine in his cage, and eats a good amount of it. I feed him peppers from the garden, frozen peas, green beans, and corn. I've been giving him a strawberry every other day for the past couple weeks. He gets a pumpkin seed each morning when I put him in his cage so I can go to sleep. He gets maybe 5-6 safflower seeds of the evening after I get up.

Tho for the past month or so we've both been eating some junk. I've been having things like pizza, and give him pieces of crust.

Stress is a big possibility. With him never knowing when I put him to bed if I'm leaving that night or not, and him having to keep himself entertained during the day, when just 2 months ago I was here with him all the time. And when I'm off, I'm up all night being noisey. Tho I'm not sure if that really bothers him, as he never makes a peep as long as I keep the lights off. If I have to turn the lights on, I'm allowed approximately two minutes before he lets me know he's not happy. His timing is pretty accurate too, lol!

Definitely gonna get him into the vet soon, cause now I'm a little worried.

They don't look like stress bars. By the way, stress for a bird is not really how we conceive of it, and is most often linked to a period of hunger or malnutrition. I looked through my collection of Peppy feathers and found some flights with the same pattern. I hesitate to use him to illustrate what is normal, but if you look at some of the Quaker pictures here, you can see several that seem to show the same pattern. Look about halfway down: www.dreamstime.com/photos-images/quaker-parrot.html

I think what you're seeing is pretty common, and you shouldn't get too stressed about it. (Who needs stress bars?) I'll be interested to see what your vet says.

Diet sounds pretty good. I doubt he has any major malnutrition from that... I think Easttex is probably right, it probably is a normal variation in feathers. Vet visit can't hurt though.

Just wanted to let you know that Bonnie's flight feathers have white edging on them...never noticed before reading your post, but she seems happy enough, so hopefully it means nothing.

Maya's have a lighter edge too, though she's grey so it's not as easy to spot. She also has white tips on her tail feathers. Sometimes this can be an individual thing in birds, a bit like a person's finger print. I agree with the other that a vet visit won't hurt but if he's eats and pooping fine it's unlikely to be all that serious. Best of luck and let us know what the vet says!
