in Thoreau’s Journal:

Green early blue-berries on hill sides passim remind you of the time when berries will be ripe. This is the ante-huckleberry season–when fruits are green.

Maybe the huckleberry- bird best expresses the season, or the red-eye.

What subtle differences between one season and another! The warmest weather has, perchance, arrived and the longest days, but not the driest. When I remember gathering ripe blackberries on sandy fields or stones by the roadside, the very berries warmed by the sun, I am convinced of this. The seasons admit of infinite degrees in their revolutions.
