The Nightingale in empty skies

I wake at dawn. No cars disturb the peace, only the joyful greeting of the birds awakening in the garden trees to join their morning chorus, not as a choir but as a company of different voices, like a great Mozart opera where individual soloists sing their own lines to make something whole, greater than its parts. Above all, the nightingale, who never sings the same note twice, or in the words of an old English writer who did not mess with short terse phrases:

But, independent of all combinations of time and place, so various, sweet, and continuous, are the notes of this bird, that, in comparison, the songs of other warblers, in their utmost extent, are insignificant. His variety appears inexhaustible; he never repeats the same note twice without some change of key or embellishment. As often, indeed, as this leader of the feathered choir prepares to conduct the hymn of natures he begins by feeble, timid, and indecisive tones, as if to try his instrument. By degrees he assumes more confidence, becomes gradually more warm and animated, till he captivates and overwhelms his audience, with the full exertion of his astonishing powers.
Nature displayed in the Heavens, and on the Earth, according to the latest Observations and Discoveries. By Simeon Shaw. (1823).

Or, apt now for our present time, Keats' Ode to a Nightingale:

That I might drink, and leave the world unseen,
    And with thee fade away into the forest dim:
Fade far away, dissolve, and quite forget
  What thou among the leaves hast never known,
The weariness, the fever, and the fret
  Here, where men sit and hear each other groan;
Where palsy shakes a few, sad, last gray hairs,
  Where youth grows pale, and spectre-thin, and dies;
Where but to think is to be full of sorrow
   And leaden-eyed despairs,
Where Beauty cannot keep her lustrous eyes,
   Or new Love pine at them beyond to-morrow.

though what, one wonders, drew Keats into contemplations of age and death at the age of 23? But he died aged 25, so perhaps his foreboding was not misplaced.

My window looks East towards the approach path for planes coming into Stansted. Usually, it is criss-crossed with contrails but this morning, the air is clean and still. Not a single plane litters the sky, and Flight Radar, usually heavy with its yellow-flagged morning traffic, confirms the desolation of lost holidays and business. Two solitary crosses mark the death of aviation.
