Hop Hop

It's him again.    I say him but I read today that the way to tell the difference between male and female robins is the shape of their hairline.  Apparently females have a v shape and males a u shape.   
I don't know whether that is a load of googling cobblers but since Hop Hop is still a youngster and has not developed his full colours yet I can't tell.  
Still a bit on the hot side but there is a welcome breeze.
