Friday 18 August proved to be opening day of the best autumn passage of Black Terns in Britain for a good few years. In fact, after two blank autumns locally in 2020 and 2021, then just a single adult in September 2022, it was really nice to see a flock linger throughout the day, gradually increasing to a peak of 11 birds. Most were moulting adults, but among them were four juveniles – these were what I focused on with the camera.
As is often the case on 'Black Tern days', the light wasn't great, but it was interesting to see how an overcast sky could nonetheless throw up a variety of light conditions as both darker clouds and brighter patches passed by overhead. A selection of images below.
