Bee orchids - Also, on the footpath by the river behind Derby Arena, a white flower, which I thought might be a mallow, or is it a garden escape?
Plus between the river footpath and Pride Park stadium: green alkanet, weld and possible perforate St Johns Wort and square stemmed St Johns Wort and in the car park on the corner of Locomotive Way and Roundhouse road there is Common Centaury in bud. I also heard greenfinches in several places, skylarks across the river and the peregrine falcon calling over the football ground. It was an amazing lunchtime walk!
