Cowslips and Primroses

In and around our" lawn" right now are lots of cowslips and primroses. Over the years,these have hybridised to give rise to  a variety of different  forms. There is just one plant with these orange flowers, the others bearing flowers of  different shades of yellow.  In extras, is an upright form of primrose (rather resembling an oxlip), followed by a more typical cowslip. While I was out in the garden looking at these varieties, I was surprised  to see five Ravens fly over! They were quite high up, and croaking loudly. ( I recorded them on my Merlin  phone  app, which also said they they were Ravens.)
