The Emu. 
adult male has concluded its moult. With the female the two 
centre tail quills are about two-thirds grown, while the others 
appear full grown. 
In the tail of the immature male there are two ages in quills 
of the full length, one being dull nutty-brown, the other half 
being yellowish. Both are very much mutilated. However, the 
yellowish set is the new one, because there is a single half- 
grown quill, fresh and yellowish. The bill of the immature 
specimen is pale brown on the proximal half and deep brown 
on the distal half There is a tendency withal to have a 
brown line at the base of the white patch near the ear coverts, 
not separating the white from the auricular patch, but with an 
inclination to do so.

[Here this is a very shy bird, flying away rapidly when 
approached, and being difficult to get near. It is generally seen 
in low scrubby bushes.]

[My experience with this bird is to find it never away from 
the thick scrub along the Fitzroy River. It is very quiet, so 
much so that I have never heard its note. It is very fond of the 
small fruit of the native fig (6/12/00). C^n 20th September I 
saw the young of this species. It is very unusual to see the 
young of Honey-eaters at this time of the year, as it is usual for 
them to breed in the heavy tropical rains. Where I saw these 
birds a heavy storm had recently occurred, and possibly that 
accounts for the diversion.]

Nine skins, including four males and five females, of which one 
is a nestling and two are young. 
The young are dated 2/2/00 and 20/5/00, and the nestling 
1/6/01. While the back of one of the young is in agreement with 
Mr. North's diagnosis — " Young birds have the upper surface
