Colonel C.H.T. Marshall observes:--"A nest of the Chestnut-bellied Nuthatch was pointed out to me at Umballa in the next garden to mine. It was about 12 feet above the ground in an old mango-tree; the locality chosen was the stump of a branch which had been cut off and had rotted down. Outside there was a great deal of masonry work as hard and firm as that on white-ant hills, in the middle of which was a neat circular hole just large enough for the passage of the bird. The masonry continued down inside the hole as far as I could see; I did not break it open, as there were nearly fledged young ones inside. I knew this because the parent birds had been seen for some days carrying in food. I did not see the nest till the end of May. The following spring I found another nest at Kurnal in a bokain tree; it was constructed after the same fashion; the nest itself, which consisted only of dead leaves, was not very far down. I was unfortunately this time (March 15th) too early for the eggs. The holes are not easy to see from the ground, as they are most skilfully concealed from view." The eggs of this species are very regular, slightly elongated ovals, scarcely compressed or pointed towards the small end at all. The shell is fragile, and is either entirely glossless or has only a trace of gloss. The ground-colour is white, with at times a faint pinkish tinge, and the markings consist of spooks, spots, and splashes (always most numerous at the large end, where they usually form a more or less conspicuous though irregular cap) of dull or bright brick-red, more or less intermingled in most specimens with dull reddish lilac. The arrangement and size of the markings are very variable. In some eggs they are all mere specks, forming a small speckly cap at the large end, and elsewhere very thinly scattered about the surface; in others many of the spots are (for the size of the egg) large, the majority are well-marked spots and not mere specks, and the whole surface of the egg is pretty thickly studded with them, while the broad end exhibits a large blotched and mottled cap. The majority of the eggs are intermediate between these two extremes. In length the eggs vary from 0·61 to 0·72 and in breadth from. 0·5 to 0·54, but the average of numerous specimens is 0·67 by 0·52.[A] [Footnote A: SITTA TEPHRONOTA, Sharpe. _The Eastern Rock-Nuthatch_ Sitta neumayeri, _Mich., Hume, cat._ no. 248 quint.
