Poem for a bird departed

Oh sweet thrush
That’s flown it’s last;
That met its end
As autumn passed.
So perfect, bright
In all your bird-like shape.
So soft, forlorn
In my hand your subtle weight
Focussed, still
And yet so full of life.
Departing departing
Oh grim and dreadful day
Your death leaves me more alone
Than even I might say.
