COLLARED SPARROW-HAWK. 
little birds were met with. Near our camp, in January, I was surprised 
to see a small male bird attacking a pair of Rose-breasted Cockatoos. 
The Cockatoos had selected the hollow branch of a tree for their nest^ 
and whilst they were trimming the entrance to their future domicile, the 
Hawk made frequent swoops at them, knocking out bunches of feathers and 
causing the Cockatoos, which were more than twice his weight, to cry out 
with pain. This battle was continued for some time, and was eventually 
terminated with a cartridge, as I hoped to have the chance of robbing the 
Cockatoo’s nest myself.” 
Macgillivray {Emu, Vol. XIII., p. 150, 1914) simply notes ; “ Seen 
several times on Cloncurry and Leichhardt Rivers. At Cape York, on 24th 
November, 1910, a nest of this species was found containing three fully 
fledged young birds^ in a Moreton Bay ash. The birds were not at all 
common.” 
A note should be given concerning Falco melanops Latham, as in 
the synonymy will be noted Accipiter melanops Strickland, Ornith. Syn., 
p. Ill, 1855. 
In the Index Ornith. Suppl., p. xii., 1801, Latham named F{alco) melanops, 
based on the Black-eyed Falcon, Gen. Syn. Suppl., II., p. 52. This name 
was founded on a drawing, and the following notes will explain the matter. 
In my List Birds Austr.^ p. 327, 1913, in Appendix B, I wrote : “ This 
was determined by Strickland as having been based upon a drawing which 
he recognised as that of A. torquatus Temm., and in the Ornithological 
Synonyms he displaces that by Latham’s species name.” Earlier in the 
Nov. Zool., Vol. XVIII., p. 246, 1912, I had explained : “ Falco melanops 
Latham, Index Ornith. Suppl., p. xii., 1801, New South Wales, may be 
referable to this species ; but in any case it is unavailable, being preoccupied 
by the same author {Index Ornith., p. 37, 1790).”
