SITTA. 131 



Measurements. Total length about 140 mm. ; wing 74 to 79 mm.; 

 tail about 42 mm. ; tarsus about 18 mm. ; culineii about 15 mm. 



Distribution. The whole of the North-West Himalayas from 

 the Baluchistan boundaries where well forested, Afghanistan, 

 N. Kashmir to the hills next the plains as far as the pines 

 continue and as far east as Garhwal. 



Nidification. This Nuthatch breeds freely throughout its range. 

 Eattray took many nests in the Murree Hills in June, and says 

 that a favourite site is high up in a tall fir-tree that has been 

 struck by lightning and cracked down the ceutre, a convenient 

 place in this crack being selected for the nest. They lay from, 

 four to eight eggs, which are just like those of the various forms 

 of Chestnut-bellied Nuthatches and measure on an average for 

 50 eggs about 18-2 x 13'7 mm. The nest is difficult to find, 

 both from its position and the cautious habits of the birds. 



Habits. This is a bird of high elevations, being found princi- 

 pally between 7,000 and 12,000 feet and, according to Rattrav and 

 others, seldom below 8,000 feet. Its range, however, seems to 

 be decided by the forest growth and it will not frequently be 

 found outside the regions of firs, pines and other coniferous 

 trees. Stoliczka says that it feeds principally on the seeds of 

 Pinus girardiana and that its voice is a loud, uniform, melan- 

 choly call, uttered while it is busily engaged in securing a pine- 

 seed in the bark of a large tree. Whitehead likens its call to the 

 French word " pain," and he and Davidson both say that the 

 monotonous, wailing cry is to be heard in the forests all day 

 dong.
