The chirruping nightjar or kayumanggi nightjar (Caprimulgus griseatus) is a species of nightjar found in the Philippines. This species was formerly conspecific with the Savanna nightjar but was designated as its own distinct species due to its differrence in calls.
EBird describes this as "Well-camouflaged nightbird, endemic to the Philippines. Inhabits open areas in grasslands, as well as scrubby forest edge and rocky river margins. Intricately patterned gray-brown, but without the white throat and tail-tips of Philippine Nightjar, and has a less contrasting wing pattern at rest. Listen for its song, a bright, rising “j’wee!”, averaging clearer and less buzzy than the song of the closely related Savanna Nightjar (under which Chirruping was once treated as a subspecies). Little-known Mindanao population may be a distinct taxa." [1]
It was once considered conspecific with the savanna nightjar, while it is significantly different in vocalization. [2] [3] This name Chirruping is based on its distinct high pitched call. Its alternate name Kayumanggi is a Tagolog word for brown, often used when describing a person's skin color.
Two subspecies are recognized:
This species is an insectivore. It forages in flight and hawks flying insects.
Breeding habits are poorly known but season is believed to be around March to May.
It occurs in grassland, open woodland, forest with scrubby outcrops, farmland, riverbanks and dried riverbeds. This species has been recorded in areas as high as 1,500 meters above sea level.
This is a newly split species and has yet to be assessed by the International Union for Conservation of Nature. This bird is believed to be common in its habitat. However, like most species in the Philippines, its population is still likely on the decline due to rapid urbanization and habitat degradation. [4]
Caprimulgus is a large and very widespread genus of nightjars, medium-sized nocturnal birds with long pointed wings, short legs and short bills. Caprimulgus is derived from the Latin capra, "nanny goat", and mulgere, "to milk", referring to an old myth that nightjars suck milk from goats. The common name "nightjar", first recorded in 1630, refers to the nocturnal habits of the bird, the second part of the name deriving from the distinctive churring song.
The savanna nightjar, also known as allied nightjar or Franklin's nightjar, is a species of nightjar found in South and Southeast Asia. The IUCN Red List has assessed the species to be of least concern because it has a large range and its population trend is stable. As other nightjars, this nocturnal bird is characterised by its large eyes, gaping mouth and excellent camouflage. It can be distinguished from similar southasian nightjar species, like the chirruping nightjar, by its unique vocalisations.
The blue-backed parrot, also known as Müller's parrot and Burbridge's parrot is a large, endangered species of parrot endemic to the Philippines. It is found in tropical moist lowland forest but is now feared locally extinct in a large part of its range including Negros, Panay, Leyte, Luzon and Polilio. The only recent records are in Samar, Mindanao and Tawi-tawi. Flocks are small and often active at night. Its main threats are habitat loss and trapping for the pet trade.
The blue-crowned racket-tail is a parrot found endemic to the Philippines. It is 27cm, basically green with a blue crown, bluish undertail, whitish beak, and dark underwings with green coverts. It was formerly conspecific with, Mindoro racket-tail and Blue-headed racket-tail
The Ameline swiftlet, also known as the grey swiftlet, was formerly considered as a subspecies of the uniform swiftlet. It is endemic to the Philippines. Its natural habitat is tropical moist lowland forests. Despite some fears around conservation, the species remains a Least-concern species.
The white-tailed nightjar is a species of nightjar in the family Caprimulgidae. It is found in the tropic regions of Central and South America.
The Long-tailed Nightjar is one of 98 species of nightjar in the family Caprimulgidae, the "true nightjars". It is a nocturnal, insectivorous bird characterized by its distinctive long tail. It is found throughout mainland Africa in open areas, arid semi-deserts, and savannas, with common sightings alongside roadways.
The Philippine nightjar is a species of nightjar in the family Caprimulgidae. It is endemic to the Philippines. Its local names are kandarapa (Tagalog) and tagolilong (Cebuano).
The Mindanao racket-tail is a species of parrot in the family Psittaculidae. It is endemic to Mindanao in the Philippines. It was previously conspecific with the Luzon Racket-tail. Two subspecies are recognized: the nominate waterstradti in the south-east, and malindangensis in the west. Its natural habitat is tropical moist montane forests. It is becoming rare due to habitat loss and trapping for the pet trade.
The Taiwan green pigeon or whistling green pigeon is a bird in the family Columbidae. The species was first described by Robert Swinhoe in 1863. It is found in Taiwan and Batanes in the Philippines.
The yellow-crowned flowerpecker is a species of bird in the family Dicaeidae. It is endemic to Luzon Island in the Philippines. It was formerly conspecific with the Flame-crowned flowerpecker of Mindanao. Its natural habitat is tropical moist montane forest. It is becoming rare due to habitat loss.
The northern sooty woodpecker is a species of bird in the family Picidae. It is endemic to Luzon, Marinduque, Catanduanes and the Polillo Islands in the Philippines. Its natural habitats are tropical moist lowland forests and tropical moist montane forests.
The grey nightjar is a species of nightjar found in East Asia, breeding from southeastern Russia south through China, the Korean Peninsula and Japan to northern Indochina and westward along the Himalayas. It is largely migratory, wintering in Indochina south to Java in Indonesia, but is resident in warmer areas in the south of its breeding range. It is sometimes treated as a subspecies of the jungle nightjar, its South Asian relative. The grey nightjar breeds and forages in early successional habitats surrounded by forests; its populations have declined since the 1970s in Japan. Like all nightjars, it is crepuscular to nocturnal, feeding on flying insects, including moths, beetles, flying ants, grasshoppers, and others.
The Philippine collared dove is a species of bird in the family Columbidae. It was formerly considered a subspecies of the island collared dove.
The flame-crowned flowerpecker is a species of bird in the family Dicaeidae. It is endemic to Mindanao in the Philippines. The yellow-crowned flowerpecker, which is endemic to Luzon, was formerly considered conspecific.

Its natural habitats are primary tropical moist lowland forest. It is now extremely rare and likely endangered. It is threatened by habitat loss and hunting.
