The Burmese Nuthatch probably breeds throughout Pegu and Tenasserim. Of its nidification in the latter division Major C.T. Bingham writes:—"On the 21st March, wandering about in a deserted clearing, I saw a couple of Nuthatches (Sitta neglecta) flying to and from a tree, carrying food apparently. Watching them closely with a pair of binoculars, I saw them disappear near a knot in a branch. The tree was a dead dry one and rather difficult to climb, but a peon of mine went up and reported five young ones unfledged, the nest-hole being 6 inches deep, and the opening, which was originally a large one, and probably caused by water wearing into the site of a broken branch, narrowed by an edging of clay. The young lay on a layer of broken leaves. As they were featherless, blind little things I left them alone, and was delighted to see the parents continuing to feed them."

The late Captain Cock furnished me with the following note a long time ago regarding the breeding of this Nuthatch:—"A very common bird at Sitapur in Oudh, every mango-tope containing one or more pairs. They pair early and commence making their nests in February, laying their eggs in March. The nests are in cavities of trees, at no great height from the ground, and unless observed in course of construction are difficult to find—the bird filling the whole cavity up with mud consolidated with some viscid seed of a parasitical plant, and merely leaving a small round hole for entrance. This composition hardens like pucca masonry in a very short time, and secures the nest from all marauders except the oologist. The nest consists of a few dry leaves at the bottom of the cavity at no great depth, and upon this four eggs are laid. The birds sit close and do not easily desert their nests, as the following instance will show. In 1873 I found a Sitta's nest in a mango-tree, and after watching the birds for some days, when the eggs had been laid I took the nest, placing my handkerchief in the nest to prevent bits of mud falling in on the eggs. I opened out the cavity, cleaning away the mud, and putting in my hand I caught the female bird. I looked at her and let her go. In 1874 curiosity induced me to look at the place again, and to my surprise I saw the cavity had been built up again. I caught a bird on the nest and took four eggs; it may have been a different bird, but there was only one pair in that tope of trees, and was probably the same bird I caught in 1873. I found another nest in my garden about 2 feet from the ground, and I often used to flash the sunlight from a small hand-mirror, that I use out birds' nesting, onto the hen bird while she sat on her eggs. Our collection contains a large series of these eggs, the produce of some five-and-twenty nests taken by myself at Sitapur."
Major C.T. Bingham writes:—"At Allahabad I found two nests of this little Nuthatch, one in July and one in September. I regret to say neither contained any eggs, though the birds were going in and out constantly. The nests were in tiny holes in mango-trees, the entrances being still more contracted by earth being plastered round."
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]
