GUARDIANS AT NIGHT 

Many birds are diurnal, but some nocturnal avian predators excel in low-light hunting, showcasing remarkable adaptations that make them vital to the night-time ecosystem.

Here are some birds who are nocturnal: 

Barn owls are mostly nocturnal, using their acute hearing and heart-shaped faces to hunt, even locating prey beneath snow without sight. 

Nightjars are crepuscular and nocturnal birds that rest on the ground during the day, utilizing their cryptic plumage for camouflage. They forage for insects at dusk and dawn. 

Nightingales are notable for their night singing. They attract mates by singing loudly in urban areas, often prompting robins. 

Corncrakes are secretive birds related to moorhens. They remain concealed but they produce a loud call at night, causing disturbances for nearby residents.

Stone-curlews, or thick-knees, are nocturnal birds with yellow eyes, known for their wailing call. They visit the UK from March to October.
