THE BIRDS OE AUSTRALIA. 
“ The breeding-season about Broome Hill seemed to commence in August 
and continue until November. Two eggs appear to be the full clutch, and 
very frequently one egg is not hatched. A neighbour of mine, who found 
several nests, told me that the second egg is laid about a fortnight after the 
first, and is not sat upon after the first chick is hatched. The nesting cavity 
is usually a considerable height from the ground, but I saw one not more than 
twelve feet from the ground that contained eggs. Although the birds are 
usually shy in their habits, I have seen two nesting-sites in trees alongside 
high roads where there was considerable traffic. At Broome Hill the following 
notes were made. August 7th, 1908. A nest containing eggs. Sept. 22nd, 1908. 
Young birds were heard in above nest. . Oct. 19th, 1908. Fledged young 
bird seen. Sept. 1st, 1910. Nest containing two eggs. Sept. 19th, 1910. Noted 
a flock of fifteen birds. Why not nesting ? Oct. 8th, 1910. Two birds noted 
moulting. Oct. 3rd, 1910. While travelling with the mail coach on the main 
high road running east from Broome Hill, the mailman pointed out to me a 
nesting cavity in a large Morrell tree, about 25 feet from the ground, on the 
edge of the road. He told me that a pair of these Cockatoos bred there for 
several consecutive years in October or November, and that as he passed 
with his mail coach, the sitting bird used to emerge from the nest and perch 
in the tree until the coach had passed. 
“ The fledged young birds are fed by the parents for many weeks after 
leaving the nest : thus on February 10th, 1914, I noted young birds being 
fed by adults in the stunted Jarrah timber close to Albany in West Australia. 
Flocks of these Cockatoos often flew over this town, which is of considerable 
size. 
North, in the Austr. Mus . Spec. Cat., No. 1, Vol. III., p. 73, 1911, has but 
few notes on this species. I quote one by Mr. G. A. Keartland : “ Although 
Calyptorhynchus baudinii is generally confined to South-western Australia, 
I saw several pairs near Mullawa, about sixty miles from Geraldton. They 
were generally out of range, but I managed to shoot one, which proved to be 
a female. Near Quindalup they are fairly common, and breed in the 
neighbourhood. Their habits are similar to those of Calyptorhynchus funereus. 
Their eggs are usually smooth and the shell fine in texture.” 
The very restricted range of this species is conducive to no subspecific 
forms. I separated an inland form, as the specimens had very strikingly 
narrow bills, but I have since received coastal birds showing nearly the same 
bill formation. In consonance with the conservative policy I have adopted 
in this work, I am not admitting the inland form as a distinct subspecies. 
It must be emphasized, however, that this non-recognition does not dismiss 
the idea of an inland subspecies altogether, but only for the time being, with
