A rather cool first week of August, however there were warm periods, in which plenty of dragonflies and butterflies were seen.

Birdwise, there are still plenty of young marsh harriers receiving food from their patient parents, bitterns have been seen from Fen and Tower Hide as have kingfishers. The passerines have seemingly found their summer hiding places, they are still there, but are quiet and quite indiscreet, until a feeding tit flock is found.

Insects include a good number of willow emeralds seen all over the reserve, small red eyed damselflies are viewable on the small pool next to reception and migrant hawkers are starting to fill the air.

 

The reserve is fully open and paths are in good condition.

Lots of stats for you there, but gives you an idea of what breeds on the reserve, the list only includes those birds surveyed, there are clearly a very large number of birds breeding which are not included. Also the surveys are mainly a snapshot of sample areas, it would be very difficult to survey the entire reedbed for example. The same locations are surveyed each year so the snapshot is directly comparable, giving us some really useful data!
