THE AUSTRALIAN DICAEUM. 
of its plumage, and the restless activity of its movements, adds much to the beauty of the 
wondrous scenery among which it dwells. It is found spread over the whole of Brazil, 
and may always be found haunting the blossoming trees and plants, dashing to and fro 
with its glancing flight, hovering with tremulous wing over the flowers while undetermined 
in its choice, and plunging its long beak eagerly into their newly-opened blossoms, where 
it finds its food. It is not known to feed while on the wing, as is the case with the humming- 
birds, but perches near or upon the flower, and clings with its strong little feet while taking 
its meal. 
The Blue-headed Honey-sucker derives its name from the azure-blue which decorates its 
head, and which is very changeable in different lights. The throat, the back, the tail, and 
the wings are black, except that the quill-feathers are edged with blue. The female bird’ does 
not possess the beautiful tints of her mate, the greater part of her plumage being green, tinged 
with blue upon the head and the scapularies ; the throat is gray. This bird is known by 
several other titles, such as the Cayenne Warbler, the Blue-headed Warbler, and the Blue- 
headed Creeper. 
Largest of all the group, the Malachite Sun-bird has long attracted the attention of 
ornithologists, on account of its great comparative size and its beautiful plumage. 
It is one of the African species, being an inhabitant of the Cape of Good Hope, where it 
remains throughout the entire year, and is in the habit of frequenting the gardens, and soon 
becomes familiar with the proprietors, provided that it be not disturbed. Sometimes the 
Malachite Sun-birds take a violent fancy to some particular shrub or tree, and may be seen in 
flocks of forty or fifty in number congregating upon its branches and amusing themselves 
among its blossoms. Day after day these birds may be seen in the same spot, attracted by 
some irresistible though obscure charm resident in the tree which they favor. The nest of 
this species is composed of very tiny twigs covered with moss, and contains four or five 
green eggs. 
The title of Malachite Sun-bird has been given to this creature on account of the brilliant 
malachite green of its plumage. 
The male bird when dressed in full nuptial costume is a remarkably handsome bird, , and 
is nearly double the length of any other species, often exceeding nine inches in total length. 
The whole of the upper surface is rich golden-green marked with a reddish bronze. The 
feathers of the throat and forehead are of the same hue, but of so deep a tone that they 
apj ear to be velvety -black at first sight, and are so constructed that they have a velvet-like 
feel to the touch as well as to the sight. Whenever the bird moves, even by the act of respira- 
tion, waves of bright hues seem to ripple upon its surface, caused by the peculiar coloring of 
the feathers, which are black at their bases and colored at their extremities. The wings and 
tail are black, and the secondaries and wing-coverts are edged with green and violet. There 
is a tuft of bright yellow feathers under each shoulder. 
The female is much smaller than her mate, and is of a dull olive-brown, except the exte- 
rior feathers of the tail, which are edged with white. 
Among other long-tailed Sun -birds may be mentioned Nectarinia pulcltella , which may 
be known by its green-edged black tail-feathers and the bright double collar of carmine and 
golden-yellow that runs across the chest. Another species, also long-tailed, Nectarinia 
platura, is remarkable for the brilliant golden-yellow of the breast and abdomen, and the rich 
violet-purple of the upper tail-coverts. 
The beautiful little Dic^eum, although very common throughout the whole of Australia, 
and a remarkably interesting little bird, was, when Mr. Gould wrote his animated description, 
so little known among the colonists that there was no popular name for the bright little 
creature. 
This tiny bird is fond of inhabiting the extreme summits of the tallest trees, and habitually 
dwells at so great an elevation that its minute form is hardly perceptible, and not even th« 
bright scarlet hue of the throat and breast can betray its position to the unaccustomed eye of
