Back to the common for more dragonflies and saw:
Common Blue Damselfly
Large Red Damselfly
An unfortunate Mallard duckling was snatched from the water by a Grey Heron and while the duck Mallard went totally ballistic the heron drowned the youngster and then swallow it whole.
A couple of girls who were chatting nearby while I was trying to photograph the Downy Emeralds (one of which landed very briefly) pointed out that a Grass Snake was swimming across the lake - the same one as I saw last time?
Finally, around the heath I saw 4 Woodlarks and at least 2 Hobbies.
