Those markings are not normal but are almost certainly the result of
psittacine beak and feather (circovirus) disease.
See how the bird is missing flight feathers? Supposing it comes down the
ground it should be euthanised
It may have circovirus but it may also be an escaped pet bird with
clipped wings that have partially moulted out. The photo isn't clear on
this - the bird would need capturing and examined to see if the flight
feathers are cut or missing. Yellow feathers are often a sign of liver
disease - a side effect of circovirus, but also due to other causes such
as an inappropriate captive diet. There are also some pied mutations of
King parrots in aviculture.
