WESTERN PACIFIC GULL. 
Nestling. Buffy-wliite, with longitudinal streaks of brown on the upper surface, the brown 
pattern somewhat darker on the head but scarcely pronounced on the under 
surface ; bill bluish horn-colour, tip hght horn-colour ; feet and iris black. 
Nest and Eggs. Undescribed. 
Breeding-season. September (Campbell). 
Nothing appears to have been written regarding the habits of this bird. 
A perfect-plumaged female killed by Mr. G. C. Shortridge has on the 
label, “ Iris ash-grey, eyelid scarlet, bill bright yellow, terminal third rose- 
red with edges of mandibles dark slate ; legs ochre yellow, pale olivaceous 
at joints, claws slate black. (During life the white of the under parts and 
neck tinged with a delicate pink, like the colour looking through a thin 
white egg.” 
An immature assuming adult plumage, procured at the same time, has : 
“ Iris dusky slate grey, eyelid brick red, bill ochre yellow, terminal third 
mottled rose-red and dark slate, legs dull ochre tinged with olivaceous ; tarsi 
in front olivaceous slate, feet (not webs) tinged above with light olivaceous 
slate, claws black.” 
The tail-coloration is quite different to that of the Eastern bird, as the 
band is much more irregular and narrower, the broadest part only 20 mm. 
deep. 
The original description reads : —

This bird was found at King George the Third’s Sound on the South-west Coast, in 
the vicinity of Seal Island. 
Is it too much to ask for field-observations to be made on this bird or its 
Eastern representative as to its plumage-changes ? It should be noted that 
birds in captivity do not exactly follow those variations which take place in 
nature, owing to the different feeding and cramped situations of the former. 
The bird figured and described is a male, collected on Mondrain Island 
on the south-east of West Australia by Mr. J. T. ' Tunney, on ^October 
29th, 1907.
