PTILOTIS UNICOLOR, Gould. 
Uniform Honey-eater. 
Ptilotis unicolor, Gould in Proc. of Zool. Soc., Part X. p. 136. 
Although I have placed this species in the genus Ptilotis, it is more than probable that it will hereafter be 
found necessary to constitute it the type of a distinct form, as on a careful comparison it will be seen that 
it differs from the true Ptiloti in some parts of its structure and in the uniform colouring of its plumage ; 
besides which, its habits and manners are also somewhat different. It is one of the many species that 
rewarded Mr. Gilbert’s researches at Port Essington ; where he states it was seldom met with in the im- 
mediate vicinity of the harbour, but that it gradually increased in number as he approached the narrow 
neck of the peninsula and the mainland about Mountnorris Bay. The situations in which it was usually 
observed were those adjacent to swampy thickets, and here it was generally seen in pairs : it appears to be 
of a most lively disposition, being always in motion ; its actions much resemble those of the Tropidorhyn- 
chus argenticeps, with which bird it often fights severe battles. When among the trees its movements are 
very amusing, and its agility in running upon and creeping round the branches in search of insects is fully 
equal to that of the Sittellce. Its flight is very short, feeble and peculiar, rarely extending to a greater distance 
than from branch to branch or from tree to tree, and is performed with a very rapid motion of the 
wings ; the tail being at the same time much retroverted over the back, gives the bird a most ludicrous 
appearance. It emits a great variety of notes and calls ; frequently giving utterance to a loud chattering 
cry much resembling that of the Myzanthce, but more often a note so similar to the well-known chirrup of 
the common English Sparrow, that it might be easily mistaken for the note of that bird. 
The stomach is diminutive but muscular, and the food consists of honey, insects of various kinds, seeds 
and berries. 
Lores and orbits deep brown ; all the plumage brownish olive ; the under surface paler than the upper ; 
primaries margined with brighter olive than the other parts of the body ; under surface of the shoulder pale 
buff; irides obscure red ; bill dark olive-brown ; naked gape fleshy white, passing into yellow at the corner 
of the mouth ; legs and feet light ash grey. 
The Plate represents the bird of the natural size.
