Where there's water there's nearly always nature - a rule of thumb brought home to me again on Monday as I took a lunchtime stroll along the River Derwent in Derby.
Pleasant surprise #1 was that a female goosander (probably one of the three I first spotted a month ago) had moved up from the edge of town and was now swimming opposite the Council House in the very heart of the the city.
Pleasant surprise #2 came just a few hundred yards further on, when I was able to watch my first ever american mink as it picked its way along the far bank for several minutes.
It never ceases to amaze me what you can find if you've got a patch of water and a spare 20 minutes to explore. Keep 'em peeled!
