There are some things that cannot be easily photographed; the scent of bluebells in Croft Wood (also known as the Great Copse) on a spring morning; the subtle fragrance of cherry blossom in the evening. It is unlikely that you could photograph a wren as it flits across your path into shrubbery and, for me at least, it is nigh on impossible to capture on camera a swooping swallow.
Today I heard the first swallows return over Radnor Street Cemetery and later saw them swooping over Kent Road. As I walked along Bath Road I watched three swallows high against the blue sky, in circled flight. When I came to Swindon just about a decade ago, the swallows in Old Town on a warm summer's evening seemed magical; they still do. I recall also them being over on Ermin Street in Stratton St Margaret; the sun was going down one warm evening as I was given an aerial display by the swallows.
If I had to pick just one thing to say I loved about Swindon, it would have to be the swallows in the summer .... mysteriously returning each year to the same terraced houses to roost in the eaves.
Note: my swallows could possibly be swifts or house martins; not entirely sure but harbingers of the happiness of summer anyway.
