I do not understand why 'anxiety' has become so commonplace in todays World. Likely, people feel a sense of general helplessness, and as a result, they become stress as a result of not knowing what to do. This stalled response is likely results in anxiety.
Our Certified Avian Vet had elected to return to where her parents live, out of a need to care for them as they become older. That has left a huge void in Avian care in my area. Because we had a true expert, the number of other Vets that see Parrots had become smaller and they have become overly busy with the influx of clients switching to they clinic. This could cause anxiety, but by simply pre-scheduling wellness appointments that does not become an issue. Point being, action displaces anxiety.
NOTE: Parrots pick-up on the emotional state of their Humans and as a result, that is more important at this point than for you to worry about something that is not likely to happen.
