Swift passage

One of my enduring memories of my time in Dubrovnik will be of the swifts - both common and Alpine - which swoop up and down the streets screeching for all they are worth. The sky is full of them in the mornings and early evenings. They were mesmerising. This is a shadow of just one of them.
My extras, for those who can bear to look, are some of the stray cats of Dubrovnik.
