There was a small, but fairly steady flow of Honey Buzzards (total: 35) and Marsh Harriers (total: 52) until late afternoon. While 11 and 18 Marsh harriers came down to roost at dusk. A few Kestrel species (4)passed high above us. A Sparrowhawk came lower down giving better views. Also 1 Hobby and 6 Common Kestrel. Maybe the highlight of the day was a flock of 71 Grey herons (my biggest flock ever) which flew by in the distance. What's more there were large numbers of Barn Swallows (600+) as well as 100+ House Martin and around 3 Sand Martin. Some "hunter" passed the time shooting at them! What a hobby! Finally a Turtle Dove, an Alpine swift, 4 Common Swift, 17 Starling, my first Grey wagtail of the season and 5 Bee-eaters of which there hasn't been many of, resting on the wires.
