BiologyNightjars return from Africa in late April and May. Upon return, males attract a mate and establish a territory by calling. During courtship males fly around a female, often wing clapping or gliding with the tail spread out and wings held up. Nests are selected by males and are usually a shallow scrape on bare ground amongst heather or bracken. Eggs are laid between mid-May and mid- July. A typical clutch consists of 1-3 eggs, and if the first brood is produced early in the season, a second brood may be possible. The migration to Africa starts in August and September (2). Nightjars hunt for insects on the wing at dusk and dawn, their agility allows them to perform rapid twists and turns in pursuit of their prey. Most of the diet consists of moths, flies, craneflies, beetles, and ants. Nightjars have an unusual serrated middle claw which they use to preen their feathers (2).
