BIRDS OF TENASSERIM. 167 



It is almost invariably found in pairs. These also feed apparently 

 entirely (I have dissected mauy) on insects. — W. D.] 



In this species, despite all that lias been said, there is no possi- 

 ble doubt, (as Davison has sexed scores of specimens in Tenas- 

 serim and the Malay Peninsula,) that the adult males have the 

 rufous head and black banded tails, and the females, the grey 

 heads and the cheftnut tails. 



The sexes do not vary in size. The following- are dimensions : — 



Length, 12-5 to 13*75; expanse, 1275 to 13*7; tail, 6'82 to 

 8-25; wing-, 4-26 to 4-62; tarsus, 0*95 to 1-12; bill from gape, 

 1-3 to 1-4 ; weight, 1-75 to 2 oz. 



Legs and feet dark plumbeous ; claws black ; bill apple green ; 

 orbital skin pale green, inclining to bluish ; hides, in the only 

 specimen in which these were recorded, dark brown. 



The males have the whole top and sides of the head, sides and 

 back of the neck, and entire mantle, and all but the tips of the 

 quills, (which are dusky or deep hair brown,) chestnut, brighter 

 on the head and neck, where the paler orange buff bases of the 

 feathers show through a good deal, darker on the other parts ; 

 rump, upper tail-coverts and tail blackish dusky ; all the feathers 

 of the latter tipped white for about half an inch, and the feathers 

 blackening and losing their bands about half an inch inside these 

 tippings ; the whole of the rest of the tail feathers narrowly, 

 closely, and rather obscurely banded with pale somewhat 

 yellowish brown ; upper tail-coverts more narrowly, more closely, 

 but somewhat less obscurely similarly banded ; rump with traces 

 of similar but still finer and closer banding ; chin, throat and 

 breast much paler than the head and back, a warm full-colored 

 buff ; upper abdomen this same color, shaded with smoky grey ; 

 lower abdomen and thigh coverts smoky grey, passing into 

 smoky dusky on the lower tail-coverts, and all these dusky parts 

 very finely and obsoletely banded. 



The females have the whole head, neck all round, chin, throat 

 and breast pale grey, becoming albescent on the lower surface, 

 and generally a little stained with fulvous on the middle of the 

 breast ; upper abdomen grey, shading into fulvous, and the 

 fulvous again passing to a dusky on the flanks and lower tail- 

 coverts and tibial plumes, which are all more or less fringed 

 with dull rusty towards the tips of the feathers ; the entire 

 tail chestnut (like the wings,) tipped for half an inch with pure 

 white, and with a sub-terminal black band of about the same 

 width.
