The nest being finished, which is the work of five or six days, but a day or two elapse, and the female is ready to deposit her eggs. The latter, to the number of two, are laid in as many consecutive days. Incubation immediately ensues, and continues for a period of eight days. Its duties devolve upon the female, who sits with commendable patience until her task is accomplished. While thus employed, her mate stands guard, or is abroad in quest of food. If any attempt is made to interfere with the nest while he is on duty, the most menacing gestures and loudest remonstrances are indulged in. Should these not have the desired effect of frightening away the intruder, he darts at his foe with wide, open bill, and endeavors to inflict summary punishment. He is so persistent in these attacks that it is often very hard to beat him off. The female, on the contrary, is of a more passive nature, quietly keeping the nest, although not unmindful of the proceedings being enacted, and only venturing therefrom when danger is imminent. These assaults continue while the nest is endangered, and even for a short time afterwards, when the birds retire to a neighboring tree to brood over their mishaps, and consider what is best to be done.
The young are objects of special interest to the parents, who render them every needed attention. When one is absent for food, the other stays at home to protect them from danger. Their food consists of a prepared mixture of nectar and soft insects, which they procure by thrusting their bills into the mouths of their parents. It was formerly supposed that this diet consisted entirely of the honey of flowers, but this opinion of the ancients was not wholly a fallacy, since a portion of nectar is taken with the insects, and supplies to the Humming-bird that kind of nourishment which the larger insectivorous birds derive from fruit. When eleven days old, these tiny creatures, in their beautiful robes of green, quit the nest, but necessarily remain under parental control a week longer, before they are able to support themselves. By some inexplicable circumstance, the young do not leave for their winter-homes until some time after their parents have departed.
The eggs are beautifully elliptical in outline, and of a pure dull white color. They measure .50 by .34 of an inch. Never more than a single brood is raised annually. Nests with eggs have been taken as late as the 20th of July, but these were doubtless laid by females whose early efforts had been interfered with.

Plate VIII.—PIPILO ERYTHROPHTIIALMUS, Vieillot.—Towhee Bunting.
The Towhee Bunting, or Ciieavink, has an extended distribution throughout the eastern portions of the United States, ranging from Florida and Georgia on the south-east to the Selkirk settlements on the northwest, and westward to the border of the Great Plains, where it is replaced by closely allied races. It breeds wherever found, certainly in Georgia, and, doubtless, in Florida, although sparingly.
According to Wilson, it is found in the middle districts of Virginia, and thence south to Florida, during the months of January, February and March; but as the weather grows mild, and Nature begins to don her livery of green, many forsake these haunts, and wing their flight to distant localities; reaching the Middle Atlantic States about the fifteenth of April, Massachusetts and Connecticut towards the last of the month, Maine and New Hampshire early in May, and the North-western States a little later.
