In America we call them Whip or wills
I don’t know where they go to rest by day, but Austin has Chimney Swifts. They don’t seem to be bothered by lights at night, as they like to swoop around big parking lots with tall lights. The lights attract bugs which attract the swifts. You hear them call but generally can’t see them unless they pass extremely close to a light. They stay above the lamps which block the glare of the lights.
