Sightings: The highlight of the morning was the immature Marsh Harrier circling over the reed bed.

Just one Swift seen early in the session. Two Magpies spent a while harassing the male

Sparrowhawk. The biggest flock (20+) of Long-tailed Tit I’ve seen this year flew over us. 

Generally, both the scrub and reed bed were quiet.
