The squeak or sharp note of the Great Crested Flycatcher is easily distinguished from that of any of the genus, as it transcends all others in shrillness, and is heard mostly in those dark woods where, recluse-like, it seems to delight. During the love-season, and as long as the male is paying his addresses to the female, or proving to her that he is happy in her society, it is heard for hours both at early dawn and sometimes after sunset; but as soon as the young are out, the whole family are mute.
It feeds principally upon insects, so long as these are abundant; but frequently in autumn, and as it retrogrades from the Middle Districts, its food is grapes and several species of berries, among which those of the pokeweed are conspicuous. While in the woods, its flight is peculiarly rapid: it dashes through the upper branches of the tallest trees like an arrow, and often sweeps from this elevated range close to the earth, to seize an insect, which it has espied issuing from among the grass or the fallen leaves.
