Autumn colours, autumn wings.

Autumn colours, autumn wings. The two arrive together, as if the season had only one great idea and spent itself carrying it out. While the trees turn red and gold and the days draw in, the storks lift off from the fields and head south, their white wings passing over the turning woods like a signature written across the season. Autumn is a departure, and the storks are its most faithful travellers.

The turning of the leaves

The leaves turn first. Almost overnight the greens give way, and the woods along the river catch fire in reds and golds that seem too bright to last. This colour is the season's way of letting go, a slow, beautiful release before the bareness of winter. And as the leaves loosen, so do the birds. The storks read the shortening days and the cooling air, and they know, without being told, that the time for going has arrived.

The shortening days

Light is the stork's real calendar. As the days shorten, the signal to move south grows stronger, and the birds answer it. There is a directness to this that has nothing to do with reason. A stork does not decide to leave the way a person decides; the waning light simply tips some balance inside the bird, and the bird goes. The shortening day is the wind of autumn, pushing the flock southward even before the first frost.

Wings over the colour

To see a flock of storks pass over an autumn wood is to see the season at its fullest. The birds fly high, white against the deep blue of an autumn afternoon, and below them the land is a patchwork of gold and rust. There is no hurry in the flight. The birds are using the last warm thermals of the year, climbing and gliding, covering the distance south in a series of long, unhurried strides through the air.

The last warm days

Autumn migration is timed to the last of the good weather. The storks leave while the days are still mild, riding the warm air before it fails them, and they keep to a route that lets them rest and feed along the way. These last warm days are the doorway of the year, the narrow season through which the birds pass on their way to a warmer one. Once the door closes, the north is theirs no longer.

A season of letting go

There is a melancholy to autumn that even the storks seem to carry, though the birds themselves would not call it that. The leaving of the leaves and the leaving of the birds are the same gesture, the same necessary release of a season that has run its course. And yet autumn is not only an ending. It is the beginning of the journey, the first chapter of the long winter story. The colours fade, the wings pass, and the year, having spent itself, turns quietly toward sleep.
