PTILOTIS FLAVIGULA, Gouwid. 
Yellow-throated Honey-eater. 
Ptilotis flavigula, Gould in Proc. of Zool. Soc,, Part VI. p. 24 ; and in Syn. Birds of Australia, Part IV. 
Turs fine and conspicuous species of Pei/ofis is abundant in all the ravines round Hobart Town, and 1s 
very generally dispersed over the whole of Van Diemen’s Land, to which island I[ believe it to be exclu- 
sively confined, for I neither observed it myself nor have I met with any example in the numerous collections 
I have received from South Australia and New South Wales. It is very animated and sprightly in its dis- 
position, extremely quick in its actions, elegant in its form, and graceful in all its movements; but as 
its colouring assimilates in a remarkable degree with that of the leaves of the trees it frequents, it Is some- 
what dificult of detection. When engaged in searching for food it frequently expands its wings and tail, 
creeps and clings among the branches in a variety of beautiful attitudes, and often suspends itself to 
the extreme ends of the outermost twigs; it occasionally perches on the dead branches of the highest 
trees, but is mostly to be met with in the dense thickets. It flies m an undulating manner like a Wood- 
pecker, but this power is rarely exercised. 
Its note is a full, loud, powerful and melodious call. 
The stomach is muscular, but of a very small size, and the food consists of bees, wasps and other Hyme- 
noptera, to which are added Coleoptera of various kinds, and the pollen of flowers. 
It is a very early breeder, as proved by my finding a nest containing two young birds covered with black 
down and about two days old, on the 28th of September. 
The nest of this species, which ts generally placed in a low bush, differs very considerably from those of 
all the other Honey-eaters with which I am acquainted, particularly in the character of the material forming 
the lining; it is the largest and warmest of the whole, and is usually formed of ribbons of stringy bark, 
mixed with grass and the cocoons of spiders; towards the cavity it is more neatly built, and is lined inter- 
nally with opossum or kangaroo fur; im some instances the hair-like material at the base of the large leaf- 
stalks of the tree-fern is employed for the lining, and in others there is merely a flooring of wiry grasses and 
fine twigs. ‘The eggs, which are either two or three in number, are of the most delicate fleshy buff, rather 
strongly but thinly spotted with small, roundish, prominent dots of chestnut-red, intermingled with which 
are a few indistinct dots of purplish grey; their average length is eleven lines, and breadth eight lines. 
The only external difference in the sexes is the smaller size of the female, which is nearly a third less than 
that of the male. 
Lores and cheeks black ; crown of the head, ear-coverts, breast and under surface dark grey, with silvery 
reflexions; a few of the ear-coverts tipped with yellow; chin and upper part of the throat rich gamboge- 
yellow; all the upper surface, wings and tail rich yellowish olive, brightest on the margins of the quill- and 
tail-feathers ; inner webs of the primaries and secondaries dark brown; under surface of the shoulder and 
wing gamboge-yellow ; abdomen and flanks washed with olive; bill black; interior of the bill, throat and 
tongue rich orange; irides wood-brown ; legs and feet brownish lead-colour. 
The young birds assume the adult colouring from the time they leave the nest. 
The Plate represents a male and a female of the natural size.
