According to Mr. Hodgson's notes and drawings this species begins to lay in April, constructing a shallow saucer-like nest of moss lined with moss-roots, in holes of trees at no great elevation from the ground. One such nest, the measurements of which are recorded, was 3.25 inches in diameter and 2 in height externally; the cavity was 2·25 inches in diameter and 1·25 inch in depth. They lay three or four pure white eggs slightly speckled with red, which measure about 0·72 inch in length by 0·55 inch in width. They breed once a year, and both sexes assist in incubating the eggs and rearing the young. Mr. R. Thompson says:--"In Kumaon the White-tailed Nuthatch breeds in May and June, laying five or six eggs, in holes in trees, especially in oaks." Colonel G.F.L. Marshall writes:--"This bird is an early breeder in Naini Tal; a nest found on the 25th April contained half-fledged young. It was in a natural hollow of a tree about 10 feet from the ground in a thick trunk; the hole was closed up with a kind of stiff gummy substance, leaving only a circular entrance about an inch in diameter, just as I have seen in nests of _Sitta europaea_. The old birds were busily engaged in feeding the young. Another nest containing young was found on the 28th April in an oak tree at about 7000 feet elevation; both birds were feeding the young, and the nest was similar to the last except that in this case it was so low down in the trunk that, sitting on the ground, I could put my ear against the hole. From a third nest, found on the 2nd May, the young had apparently just fled. My experience bears out Mr. Hodgson's observations: I have often been up here in May and June searching closely and never found a nest; this year I came up for the first time in April, and within a few days find three nests with young. I may add that after the 10th May all the Nuthatches I have seen were in small parties, apparently parents with their young." 316. Sitta cinnamomeiventris, Blyth. _The Cinnamon-bellied Nuthatch_.
