There's something I often say when asked for this kind of advice: when in doubt call the vet. A vet visit may not actually be necessary but it would be a good idea if your parrot shows any signs of illness or distress. Some questions you would likely be asked... Is your parrot eating and drinking normally? Do his poops appear normal? Is he as active and vocal as usual? If there's anything that doesn't seem right then a vet visit is needed. If things are normal, a phone conversation or E-mail exchange with your vet might be enough.
