Thank you Frank and very interesting.

As a recent 'Perthling' I was told that they were going to be tricky birds to 
get locally. Good to see regardless.

I can confirm that at least two of these eight birds were begging juveniles, 
the others were one sub-adult male, 2 adult females and three adult males. They 
spent all day stripping the trees of seeds and only briefly returned today 
before moving on.
