Conure poop

[Theo_the _best_birb!!!]

Hey everyone! So this morning I have my conure dragon fruit with his other leafy greens and fruit he also had a sprinkle of plain oats, chia seeds, and tops pellets as well as tropical pellets. It was the first time I saw it in his feces. There was little black specks. So my question is do you think it is caused by the dragonfruit he has not had it in awhile. Thanks ! He has a vet appointment in December with our avian vet and gets one every six months. Or occasionally annually
