On a hot day in August...
In summer this year (2016) the warm dry weather enabled the local swallows to have two broods. On a hot week in August as many as 30 swallows visited my site. The wild flower areas meant plenty of flies for them. every now and then they dived to my pond for a drink. I set up an HD TVI CCTV camera with a camera next to the pond to film them . Fortunately mains power was close at hand, which made it easier to using an HD camera. the swallows move so fast, they can only be seen clearly by slowing down the video playback.
