I will certainly give a report Glen. It was in my late teens when I last went to watch and hear some Nightjars. That was with a local club myself and a few friends belonged to at the time. They are very territorial and I very much remember one swooping close enough to feel the air move a bit, which they are aparently are renowned for doing. I really looking forward to going.
Dan .. Whip -poor- whill, is certainly another fab and mysterious name used widely over here. But also in different countys in the UK where they reside they have even more local variations other to Nightjar ie bracken owl, moth hawk, dew-fall hawk, churr owl. One name in Ireland is a spinner, and in Scotland wheel -bird.
