If you look up at the darkening sky, you might see the silhouette of a bird with pointed wings and a long tail, a nightjar. Nightjars are summer migrants, arriving from their winter home in the scrub grasslands of the Democratic Republic of the Congo in late April or May. One of their favoured breeding areas is heathland, but also moorland, and they have taken to nesting in recently cleared conifer plantations. Luckily he noticed the bird at the last minute and took this picture. If you want to experience the thrill of hearing this strange bird over the darkening heath, or perhaps seeing one, then you only have a few weeks left.
