SITTA. 127 



batched in the end of March, and eggs sent me by Col. Harington, 

 taken on the 22nd of that month, were on the point of hatching. 



Habits. Those of the genus, and there seems to be nothing 

 calling for notice. They are found between 2,000 and 5,000 feet, 

 never in the plains, and are forest birds, thougli like most 

 jSTuthatches they keep to the more open parts, the outskirts, or 

 to partially cleared or deserted cultivation clearings in which the 

 dead trees are still standing. 



(113) Sitta europaea nagaensis. 



Austen's Xutiiaxch. 



SiUa ncK/aensis Godw.-Aust., P. Z. S., 1874, p. 41 (Sopremak, Naga 

 Hills/ ; Blanf. & Gates, i, p. .302. 



Vernacular names. Baomojo-r/ophu (Cachari); Hnet-pija-chouk 

 (Burmese). 



Description. Upper plumage, closed wings and central tail- 

 feathers slaty-blue-grey ; a black line from the bill, through the 

 eye to the nape; primaries and secondaries black on the inner 

 webs; outer tail-feathers black, the three or four outer pairs with 

 a white subterminal spot on the inner web and the outermost 

 pair with an oblique white band on the outer edge ; sides of the 

 head and neck and lower plumage grey ; sides of the body rich 

 chestnut ; lower tail-coverts white tipped and edged with chestnut ; 

 the usual white patch on base of quills. 



The female only differs in being a trifle duller. 



Colours of soft parts. Iris dark brown, bill slaty-grey, the 

 terminal half blackish ; legs and feet greenish brown. 



Measurements. Length about 130 mm. ; wing 74 to 78 mm. ; 

 tail about 40 mm. ; tarsus about 18 mm. ; culmen about 15 mm. 



Distribution. Hills South of the Brahmaputra, Chin Hills and 

 Kachin Hills. Kinuear's Sitta e. grlseiveniris (Bull. B. O. C. 

 Ix, p. 142, 1920) seems to be the same as this bird. It is possibly 

 a purer grey, but as all the specimens of Austen's Nuthatch in the 

 British Museum are very poor specimens and some of the Chin 

 Hills birds taken elsewhere are quite indistinguishable, I consider 

 this name to be merely a synonym of nagaensis, 



Nidification. This jN"uthatch breeds in the Kachin Hills in 

 April and probably also March and May. Eggs taken by 

 Col. Harington were placed in the usual kind of holes in trees and 

 were plastered up with clay masonry, reducing the entrance to a 

 size just sufficient to allow ingress and egress to the parents. 

 The nests were of moss with a lining of fur, and contained two to 

 four eggs just like those of S. c. castaneiventris and measurino- 

 about 18-9 xl41 mm. 



Habits. This is a forest form found up to the highest hills, 

 9,000 or 10,000 feet and apparently down to about 5,000 feet, 

 below which S. c. neglecta takes its place.
