So photographed the black darters and chatted with Sam and Gary. Watched a female/imm marsh harrier hunting some way off and then 5 buzzards playing with a male kestrel.
Walked down to the hide, looking at more dragonflies, including a few Highland darters and golden-ringed but didn't get to identify two large hawkers with blue spots down the abdomen.
A cuckoo flashed past the hide. I'll be honest and say that I thought it was a male sprog but Gary corrected me and yes, I'll admit it, a cuckoo it was.
3 roe deer were out on the marsh and a couple of dark green fritillaries were on the grassy slopes nearby.
Back to the centre and met a local RSPB volunteer who invited me to go for an evening meal at his house, so thanks Laura for the mackeral and new potatoes. We also went to see the nearby Ruthven Barracks, scene of various Jacobite battles.
Slept nearby [!] and watched the Perseides shooting stars and occasional satellite go over in the clear sky.
A lovely day.
