I made two visits to the local Trinity Hill Nature reserve whilst in Dorset. The first visit was with Justin and we had two churring Nightjars exactly thirty minutes after sunset but no flight views. A Tawny Owl was calling throughout our visit.
The following night I returned later and stayed longer. The churring was more prolonged and I did observe some wing clapping and a close fly by. Not quite Forest of Dean standards but it was perhaps a little early.
