Purple Martin. This, the largest and in many respects the most beautiful of all our Swallow tribe, is the most local and the least numerous. In New England and, perhaps, in most of the northern states generally, this fine bird is steadily diminishing in numbers. The English Sparrow often takes possession of its boxes, ruthlessly kills the young Martins or throws out the eggs, and usually succeeds in routing the colony and appropriating the boxes. When measures are not taken to abate the Sparrow nuisance in the immediate vicinity of Martin colonies, the usual result is that the Martins are forced to abandon their houses. The habit of putting up houses for the accommodation of Martin colonies is not as common in the north as it formerly was, and to this indifference to the Martins’ presence, to persecution by the Sparrow, and to losses due to the prevalence of cold storms during the nesting season, no doubt, is due the present scarcity of the bird. From the standpoint of the farmer and the fruit grower, perhaps, no birds more useful than the Swallows exist. They have been described as the light cavalry of the avian army. Specially adapted for flight and unexcelled in aërial evolutions, they have few rivals in the art of capturing insects in mid-air. They eat nothing of value to man except a few predaceous wasps and bugs, and, in return for their services in destroying vast numbers of noxious insects, ask only for harbourage and protection. It is to the fact that they capture their prey on the wing that their peculiar value to the cotton grower is due. Orioles do royal service in catching weevils on the bolls; and Blackbirds, Wrens, Flycatchers, and others contribute to the good work; but when Swallows are migrating over the cotton-fields they find the weevils flying in the open and wage active war against them. —H. W. Henshaw, B.B.S., in _Value of Swallows as Insect Destroyers_. “That Wise Man didn’t say anything about Chimney Swallows, and, please, Gray Lady, you left them out, too,” said Sarah Barnes, the moment the scrap-book closed, “and I know they catch lots of flying bugs.”
