I spent an hour yesterday and this morning waiting for a Little Bittern, without any serious expectation of seeing one. Too few bitterns, too much typha. However there were certainly two different birds calling yesterday. From the hide
this morning one could see at least 5 dragonflies being despatched by busy RWs. The D-flies seem to be all the one species. I can confirm the RWs can snatch them from the air. That motionless hovering might be clever, but is not necessarily advantageous
from a natural selection viewpoint. Catching the insects took less time than removing the wings.
