X, FAMILY COLOPLERIDZO, (THE Genus Tyrannus. Kingbird fly-catcher. Summer resi dent, common; insectivorous. Beetles, grasshoppers, crickets, and winged insects of all descriptions form his principal summer food; in autumn berries constitute a favorite repast. Reader, see him. perched on an old mullen stalk, watching all around, and capturing every insect that comes in his sight, and say whether he does not pay for the few bees he may destroy.
Genus Myiarehus. Great-crested fly catcher. Summer re. i den t, frequent ; insectivorous; dwells m ostly in f °rests and feeds on such insects as are found there Genus Sayornis. Pewee fly-catcher. Summer resident, common; insectivorous. This familiar and industrious destroyer of insects needs no introduction, and is capable of telling ite own story.
Gentle Coutopus. Olive-si led fly-catcher. Summer resident, not frequent; insectivorous; feeds on others of the genue.—Wood pewee fly-catcher. Summer resident, common; insectivorous. These two species are very
similar and among the most active and industrious fly catchers.
Genus Empidonax. Trail's fiy-catcher. Slimmer resi dent, frequent; insectivorous.—Least fly-catcher. Summer resident, frequent; insectivorous.—Small green-created fly-catcher. Summer resident, common; insectivorous.— Yellow-bellied fly-catcher. Summer resident, frequent; insectivorous. All the species of this genue, indeed all the family, possess similar habits. We can hardly walk out on a summer day without seeing some of them perched on a fence stake or dead bongh intently watching for their prey, and woe betide the insect, whether beetle, moth, or fly, which may dare to show itself either on the ground or wing. Tbe feat accomplished, they return to the same perch to await the appearance of other prey. Surely no observer can be so obtuse as not to appreciate the service thus rendered.
