Nightjars are nocturnal birds and could be seen hawking for food as dawn and dusk. Along with long tails and pointed wings, their shape is the same with a cuckoo or kestrel.
Their grey-brown, cryptic, streaked, barred and streaked plumage offers perfect camouflage during the daytime. Further, they have an almost mystical reputation with their silent flight and their supernatural ability to take milk from goats.
They are typically seen on the heathlands, open woodland, moorlands with clearings and lately felled conifer plantations. Nightjars reach around 25 to 28 cm long and with a reddish-brown plumage, which resembled tree barks.
