The birds flew past Sutton

Another weekday afternoon in south London. It is still BST. 

A non descript building by the railway station witnesses a flock of white geese slowly rise from the eastern sky.UFOs, said a colleague, unsure of the species.

The dark grey sky on the west, gloriously dotted with moving white silhouettes of the travellers. Rather like a clear night of stars. Croydon to Heathrow, the flight path.

Across and upward, climbing over a rainstorm, spanning large distances in only a few short minutes.

The sky full of birds moves as one towards the north west for possibly a thousand more miles.The city moves on detached and oblivious of this marvellous event!
