In such situations immense numbers congregate at the breeding-season, separating into pairs to assume the parental joys and cares. "When incubation has fairly commenced," observes Sir William Jardine, "the common or moor often appears alive with their active motions; no stranger or intruder can enter upon their haunts without an examination, and both, or one of the pair, hover and fly around, tumbling and darting at him, and all along uttering their vehement cry of Peeswit.
