The swallows and swifts spend hours on the wing, turning to the right or to the left, upward or back, in pursuit of winged insects. Many other birds, notably the warbler family, take occasional flights after some insect which they have startled from the leaves. The habits of another large family of birds, the Flycatchers, are a compromise between these two methods of obtaining food. Selecting some post of observation, such as a dead limb, a fence, or the stalk of a stout weed, they wait patiently, keeping a sharp watch of the air about them. At sight of an insect flying near, they fly out in pursuit. If one is near enough to the bird, a click of its bill will announce the fate of the insect. The Flycatchers then return to the same or a neighboring perch.

The family is not, on the whole, very good-humored; in fact, they might justly be accused of irritability and pugnacity. The Kingbird, in particular, the head of the house, is noted for his constant attacks on any winged creature that approaches his nest. It must be admitted, however, that when nesting time is over, he lives very peaceably with his neighbors; but while the female is brooding the eggs or young, the excited cry of the male is constantly heard, and every Crow that comes in sight is pursued, sometimes for a mile. The Kingbird gets above his victim and darts down at its head; the Crow can be seen wincing at each vicious jab of the bill. One or two observers have actually seen the Kingbird ride on the Crow's back for some distance. The Kingbird has a patch of red concealed under the black feathers of his crown; when he is angry or excited, these red feathers blaze out. They are very rarely seen by men, but I imagine the Crows see them oftener than they like.

Apple trees in old orchards are favorite nesting places of the Kingbird, and no pains are taken to conceal the nest. It is composed of twigs loosely laid together, and often festooned with white strings or the dry, woolly heads of the mouse-ear everlasting. The inside of the nest is neatly lined with feathers, horsehair, or roots, and contains from three to five white eggs spotted with brown. The Kingbird is here from the first of May to the first of September, but like all strictly insectivorous birds, it must spend the winter far to the southward. The bird's only notes are the shrill cries, kipper, kipper, given singly or quickly repeated. In spring the birds often mount to a considerable height, uttering this cry continually, and apparently attempting, by this exhibition, to express the emotion common to all creatures at this period of the year.

The Kingbird is a very satisfactory bird to beginners; the color pattern is so marked and the bird is so fond of exposed situations that it is seen and recognized without difficulty. Except the Cedarbird, whose tail is tipped with yellow, I know no other small bird of the eastern United States whose tail feathers are all tipped with a regular edge of light color. The Kingbird is the bird most commonly seen from a car window; in almost every field, the mullein stalks or wire fences will display one or more individuals, their white breasts or black and white tails showing conspicuously in the landscape.

The Kingbird has often been accused of destroying honeybees. Even allowing that individuals occasionally do some damage in this way, the good services of the race in destroying harmful insects far outweigh these injuries, and the remedy is to drive the bird away from the hives, not to kill it.
