T h i s beautiful species of Gull is abundantly dispersed over the coast of Van Diemen’s Land and the southern
coasts of Australia generally; it also frequents the rivers and inland lakes wherever they occur of any extent.
There is a Gull in Torres’ Straits so similar to the bird here represented, that its larger size is the only
difference I have been able to detect between them; should future research prove them to be mere local
varieties, then the range o f this species may be said to extend over the whole o f the coasts of Australia.
Although never characterized by any dark colouring o f the head, it is in every respect a true X em a ; like
the other members o f that genus, it frequently congregates in immense flocks, and colonies of many hundreds
have been found breeding together, sometimes on the marshes, at other times on the low small islands ; a
colony of this kind existed on Great Actason Island in D’Entrecasteaux’ Channel when I visited it in 1838.
The flight of this little. Gull is light and buoyant in the extreme, it runs over the surface of the ground
with lightness and great facility, and it is altogether one of the most beautiful and fairy-like birds I have
ever met with.
Its nest is formed o f a few rushes and grasses, and it lays four or five eggs, which differ considerably in
colour, hardly any two being alike; the ground colour varying from pale greenish to dark brownish olive;
in some instances slightly, in others largely blotched and streaked with blackish brown ; they also vary in
shape, some being shorter and thicker than others.
The two sexes are precisely alike in colour and may be thus described:—
Head, neck, all the under surface, spurious wing, rump and tail white ; back and wings delicate grey;
primaries white, eccentrically marked with black, largely on their inner and narrowly on their outer webs,
and largely tipped with the same hue with a slight fringe of white at the extremity ; eyelash, bill, legs and
feet deep blood-red ; nails black ; irides pearl-white.
The figures are of the natural size.
