Sticklebacks swim over the bare mud near the centre of the stream. There are 20 or 30 of them within a square yard. They're all facing upstream, but they don't behave like a shoal, moving as one. They react and interact as individuals. If I could get a closer view I would probably see some nesting activity in progress.
Just yards away from this quiet backwater the traffic rumbles away continuously along Westgate, one of the main thoroughfares into Wakefield.
Westgate Beck links with the stream I mentioned yesterday - but their are no obvious signs of Water Voles here. The banks are entirely encased in brick, so the voles can't make their burrows here.
By the way, this is old brickwork so I guess that the bricks were probably dug as clay and fired at Westgate Brickworks which until the 1960s stood half a mile upstream on the site of the present Morrison's supermarket.
