Macaws use many different types of visual communications.
Blushing their bare facial skin patch can mean excitement (E.g. if seeing their favourite person), aggression (E.g. when fending off competition), or can be used to attract a mate.
The raising of the head feathers can again have several meanings - aggression, arousal, excitement, etc. On the other hand, if the head feathers are held flay tightly against the head, this generally means the macaw is frightened,, stressed or unsure.
Macaws can use stomping to display their feelings too. By stomping up & down a perch on tall legs, they can use this to intimidate competition, to attract a mate, or as a way to interact with their human (dancing).
Raising wings is used to make a macaw look bigger than what it really is & is used to scare off aggressors or intimidate competition. It can also be used as part of the breeding display. Beware approaching a macaw that has raised its wings!
Tail fanning again can have different meanings. It can be a warning to predators, a display as part of the mating ritual, excitement, etc etc.
Basically, visual displays of macaws (& any parrot) can mean different things, but to understand them properly, you need to look at the factors surrounding that display.
