Tracey Emin, recalling Madeline Basset, described birds as "the angels of this earth".
I prefer Ted Hughes’ take on them:
by Ted Hughes
Terrifying are the attent sleek thrushes on the lawn,
More coiled steel than living - a poised
Dark deadly eye, those delicate legs
Triggered to stirrings beyond sense - with a start, a bounce, a stab
Overtake the instant and drag out some writhing thing.
No indolent procrastinations and no yawning states,
No sighs or head-scratchings. Nothing but bounce and stab
And a ravening second.
Is it their single-mind-sized skulls, or a trained
Body, or genius, or a nestful of brats
Gives their days this bullet and automatic
Purpose? Mozart's brain had it, and the shark's mouth
That hungers down the blood-smell even to a leak of its own
Side and devouring of itself: efficiency which
Strikes too streamlined for any doubt to pluck at it
Or obstruction deflect.
With a man it is otherwise. Heroisms on horseback,
Outstripping his desk-diary at a broad desk,
Carving at a tiny ivory ornament
For years: his act worships itself - while for him,
Though he bends to be blent in the prayer, how loud and above what
Furious spaces of fire do the distracting devils
Orgy and hosannah, under what wilderness
Of black silent waters weep.
As anyone who has to make up words for a living (or has ever tried to write the perfect letter, or school essay, or note in a colleague’s birthday card) might recognise, this is really a poem about the horrors of writer’s block.
