Yellow Blacks "in the pink".

Yesterday was a beautifully cool day; a max of 25C

The flock of a dozen or so Yellow Tailed Black cockatoos was back again.

Unlike yesterday, when they had sat in one place for as long as an hour at a time, with their wings held out from their bodies and beaks open, they were very active.

They ate, talking quietly to each other, and then at intervals took short flights around their currently preferred food source here (PInus radiata) and longer ones along the valley, calling all the way,  and back again.
It was great to see.



It's been two years since I have been able to get a good photo of them, so today was a special treat.


There is some dispute about what to do with the Pine Trees.
Pinus radiata

They are a pest plant in our bush.
Many want to remove them, but imo a staged removal is vital for these birds, although they are a major means of spreading the seeds, so it is a vexed issue.

We need to undertake major replanting of their original food plants, notably Hakeas, Banksias and Sheoaks before removing any more of the pine trees.

"Dispersal
Seeds spread some distance on the wind, and are also carried into bushland by Yellow-tailed Black Cockatoos.
Impact on Bushland
Radiata Pine establishes readily, creates dense shade, and carpets the ground thickly with needles. It depletes the soil of nutrients and water, changes soil chemistry, and excludes native plants. It favours the growth of weed seeds dropped by perching birds. A significant fire hazard."

And what we most certainly do NOT need here is anything that adds to our already VERY significant bushfire hazard.
