Please do not venture into the ‘conservation area’ at the back of W lake [which requires agreement from the rangers in any case], to avoid disturbance of [a] the heron and [b] other species breeding in that area. The best viewpoint is the grassy ‘beach’ at the S end of W lake where you can view with a ‘scope into the trees into which it went this morning.

PS this afternoon best viewing point was from the viewing area on the left halfway along the central path about 50m before the main bridge.
