both these forms were living together and inter-breeding. O n 
June 8, 1919, he took the eggs and made skins of a nesting pair, 
in which the striations were absent in one sex and present in 
the other. These skins are now in the South Australian 
Museum. 
It is fairly evident that these variations are not seasonal, 
though they are probably in some measure affected by both sex 
and age. More material from these very widely separated 
localities is needed to enable one to assess fully the value of 
these factors.

A Wonderful Cockatoo. —A tennis match was played at Bell- 
trees to-day, and a number of players came from Stewart's 
Brook, some 14 miles distant. Among them was Miss Dulcie 
towns, who owns a pet White Cockatoo (Kakatoc galerita) 
which is about ten years old, very tame, and was secured from 
a nest in the district. This fine bird followed Miss Towns 
during her 14 miles drive to Belltrees, frequently flying well 
ahead, settling in a tree, and waiting until Miss Towns drove 
near; then the bird flew on again. This was kept up until Bell 
tiees was reached. On arriving at the boarding-house, the bird 
followed Miss towns through the front door, and alighted on 
the dining table. On the way down from Stewart’s *Brook a 
lock of White Cockatoos was passed in the forest, but the pet 
bird flew on, and took no notice of them. At Belltrees to-dav 
this Cockatoo flew after Miss Towns to the tennis court (about a 
quarter of a mile from the boarding-house), and there sat in a 
tiee watching the game. When afternoon tea was served it 
came down out of the tree, had something to eat, returned to 
the tree, and sat there until the game was finished. Eater, Miss 
I owns started back to Stewart’s Brook, the bird following her 
frequently flying high overhead, but keeping well in front most 
of the time It was dusk when they arrived home. The Cockatoo 
made a flight to-day of 28 miles when following Miss Towns—a 
wonderful performance. 
At her home Miss Towns generally keeps the Cockatoo chained 
up, and states that sometimes he bites the chain through, or 
smashes ,t with h.s powerful bill. The bird is a good talker, and 
mnmes well -Sid Wm. Jackson, R.A.O.U., Belltrees, Scone
