My wife captured a few shots and, as well as the lead image, there are more in the video.
She spotted the creature and was definitely on form because, prior to that, she pointed out a ‘goldcrest’ which, as soon as I looked at it through the binoculars realised that it was actually a firecrest.
Unfortunately, we weren’t able to get any photographs of that as it ‘disappeared’.
Birds have a habit of doing that.
