8 May 2023 Pink & Grey Gallah Flock joined by White Cockatoos

i walk the dog at this oval atleast once a day and for the past week or so ive been seeing this mixed flock, White Cockatoos with Pink & Grey Gallahs. As the latter outnumber the former id say its pretty safe to assume that the white cockies have joined the flock. They may have separated from thier own famalies in stormy westher or they have been driven out, like leper were once treated, first you segregate then you isolate with misery and death to follow as in the case of leper colonies. Most of the cockies are/look very old and this may have been one of the reasons behind not only being driven from the flock but also one of the alternatives of simply getting lost ? Anyway, the whites are outnumbered by pink & grey gallahs and these look like the gallahs flock looks like its made up of parents and/or grand parents with other paired off younger birds and then juveniles and teens or vis a vis. This is conjecture on my part so feel free too correct me.
