Thank you for the prompt reply Joel.
My bird, Mario, and the budgie, Gaston, have been together for the past 3 years. They've been with me for the past two years in the same cage with the same conditions, food, etc. Nothing has changed. They are next to a window that gives indirect sunlight (no drafts). Aside from millett every Sunday and recommended parakeet seed from a pet store, neither of them will eat any fruit or vegetables, though I've tried multiple kinds several times. The bird exhibits the same eating patterns as before so I have no reason to assume it's not eating.

I haven't checked the breast bone, but I will do so.
He's started to breathe heavily in the past few days in the PM, but not in the morning. He eats gravel, there's a calcium block, cuttle fish in the cage.
Cage and water dish are cleaned regularly and thoroughly. I use corn cob for bedding. Droppings look OK to me.
I've owned other parakeets, but this is weird behavior. It's like he's depressed.
