THE AUSTRALIAN NATURALIST, ‘ 43 
feathers to the scalp, purposely produced a point witli this 
object, then the border-line between the mere tool-user 
and the tool-maker has been crossed. 
Mr. Froggatt contributes notes as follow:—In regard 
to the intelligence of Cockatoos and Parrots, this is a very 
interesting note to Field Naturalists. It is more remark- 
able for a bird to make a scratching tool than to, build 
some of the wonderful nests which they construct. In 
the Brewarrina district my attention was often called to 
large patches of bark being nibbled off the stems of 
White Gums by the Galah Parrots below the openings to 
their nests. Bushmen declare that the bird does this the 
keep the Monitor ‘‘Gohanna’’ Lizard getting a foothold 
when trying to rob the nest, which it could readily do if 
the bark remained. 
MisTAKEN Burrerruies—In Nature, Vol. 95, there 
are a number of most interesting communications on But- 
terflies mistaking various brightly-coloured objects for 
flowers, and attempting to feed thereon. 
Prof. E. E. Barnard, of Yerke’s Observatory, Wis- 
consin, U.S.A., relates seeing a butterfly (not named) 
alighting on a peacock’s feather, which a man had in his 
hat, and attempting to find food in the ‘‘eye’’ of the 
feather. 
Prof. H. O. Forbes describes seeing a species of 
Pieride, Appias nero, in Sumatra, deceived by brown 
withered leaves, to which the butterfly itself bears a close 
resemblance, and endeavouring to associate with them, 
thinking they were fellow-butterflies. This incident is 
fully described in Forbes’ ‘‘A Naturalist’s Wanderings,”’ 
p. 130. 
Prof. G. H. Bryan says: ‘‘In this connection the case 
should be recalled of the Cleopatra butterfly of southern 
France and Italy, the close relative of our English Brim- 
stone. By waving a grass-green butterfly net in its vicinity 
I have frequently attracted the yellow-and-orange coloured 
males, which will flutter after the net and endeavour to 
settle on it. “The female is similarly coloured to the fe- 
male Brimstone, but is rather larger. A blue net fails 
to attract them.”’ 
A highly-interesting incident is related by Mr. E. A. 
“Martin, of the Grange Wood Museum, South Norwood :—
