The Night Heron suddenly re-appeared in flight at around 7:30 p.m. and eventually landed in the large tree opposite the main bridge. It then took off, flew high down E lake and landed in a tree on the far shore of E lake [from the cafe]. Difficult to see there [into the sun] but viewed thro’ a scope from the square platform halfway along the main boardwalk. Hopefully it will stay until tomorrow. Got some stonking pix which I will post in due course. Well done Annie for recognising it as something different.
