A very short visit this afternoon to see if the Bittern was showing on the streamside lake resulted in no Bittern but I didn`t mind because I was more than compensated by some great action flying by two Sparrowhawks,both over and through the west scrub.I at first took them to be a pair but they appear to be two males (they look the same size) their underparts are bright and both look to have greyish heads.
