The moon in April is an important factor in the progress of that event—the coming of the birds—which makes every spring memorable¹. While not disposed to wait upon it too long, still, there is little doubt but that the birds that have been wintering afar south travel very largely by its light, and when it happens that the moon fulls between the middle and the twenty-fifth of the month, the flights of thrushes, orioles, wrens², and other migrants reach us a week earlier than when the nights are dark during the same period. Temperature, storms, and general backwardness of the season do not seem to have a like importance in bird economy.

Of course, by the coming of the birds I do not refer to the pioneers that are in advance of every company. Indeed, I have seldom announced the first of the season, but 72I have been met by the man who was at least one day ahead of me; so firstlings are not favorites.

There is every year the one memorable morning when we can say, in broad terms, “The birds are here.” When the oriole whistles from the tallest tree in the lawn; when the wren³ chatters⁴ from the portal of his old-time home; when the indigo-finch sings in the weedy pasture; when lisping warblers throng⁵ every tree and shrub⁶; while over all, high in air, the twittering swallows dart⁷ in ecstasy⁸; and at last, the day-long concert over, whippoorwills in the woods pipe their monotonous⁹ refrain. The Indians were right: when there came such days as this, they had no further fear of frost, and we need have but little. Our climate certainly has changed slightly since their time, but we have in such a bird-full day an assurance that the clinging finger-tips of Winter have at last relaxed and his hold upon our fields and forests is lost.
