In most locations where I encounter a Grey Heron (Ardea cinerea) they are very flighty and don't allow a close approach. More recently I have had much better experiences with several individuals in Bushy Park where they are far more tolerant of human movements.
This week one individual was on sentry duty but later flew down to allow some rewarding close photos.
Camera Critters, Saturday's Critters and I'D-Rather-B-Birdin'. FAB.
