Mr. Paine states that this Warbler is a resident, but not very common bird, in Randolph, Vt. He has usually noticed it in the midst of thick woods, not generally in tall trees, but among the lower branches or in bushes. The song he describes as very short and insignificant, its tones sharp and wiry, and not to be heard at any great distance. He knows nothing as to its nest. They arrive at Randolph from the South about the middle of May. We are indebted to Mr. John Burroughs for all the knowledge we possess in relation to the nest and eggs of this species, which had previously baffled the search of other naturalists. He was so fortunate as to meet with their nest in the summer of 1871. Early in July, in company with his nephew, Mr. C. B. Deyoe, Mr. Burroughs visited the same woods, in Roxbury, Delaware County, N. Y., in which he had in a previous year found the nest of the Mourning Ground Warbler. The trees were mostly hemlock, with an undergrowth of birch and beech. They first noticed the parent birds with food in their bills, and then set about deliberately to find their nest by watching their movements. But the birds were equally vigilant, and watched them quite as determinedly. “It was diamond cut diamond.” They were so suspicious, that, after loading their beaks with food, they would swallow it themselves, rather than run the risk of betraying their secret by approaching the nest. They even apparently attempted to mislead them by being very private and confidential at a point some distance from the nest. The two watched the birds for over an hour, when the mosquitoes made it too hot for them to hold out any longer, and they made a rush upon the ground, determined to hunt it over inch by inch. The birds then manifested the greatest consternation, and when, on leaping over an old log, the young sprang out with a scream, but a few feet from them, the distracted pair fairly threw themselves under their very feet. The male bird trailed his bright new plumage in the dust; and his much more humbly clad mate was, if anything, more solicitous and venturesome, coming within easy reach. The nest was placed in the fork of a small hemlock, about fifteen inches from the ground. There were four, and perhaps five, young in the nest, and one egg unhatched, which, on blowing, proved to have been fresh. The nest measures three and a half inches in diameter, and a trifle more than two in height. The cavity is broad and deep, two and a third inches in diameter at the rim, and one and a half deep. Its base and periphery are loose aggregations of strips of decayed inner bark from dead deciduous trees, chiefly basswood, strengthened by fine twigs, rootlets, and bits of wood and bark. Within this is a firm, compact, well-woven nest, made by an elaborate interweaving of slender roots and twigs, hair, fine pine-needles, and similar materials.
