Grey Nightjar

The grey nightjar is a medium-sized nightjar with a large head, large eye, long tail, weak bill and short legs, with mottled plumage very like that of the Himalayan subspecies of the jungle nightjar. The feathers on the nape have pale brown spots at the tips. It breeds from south-eastern Russia south through China, the Korean Peninsula and Japan to northern Indochina and westward along the Himalaya (Wikipedia, general species account).

It is largely migratory, wintering in Indochina south to Java, but resident in warmer areas in the south of its breeding range. Its habitat can be up to 3,300 m and includes forest, shrubland, cliffs and buildings. Crepuscular to nocturnal, it feeds on flying insects, and its song is a series of hollow byuck notes lasting 2–4 seconds. Breeding is between May and July, with two eggs per clutch and one nesting cycle a year. SoIB 2023 lists it as a resident and summer migrant of non-specialised habitat that eats invertebrates, and does not assign a priority category (Wikipedia, general species account; SoIB 2023).
