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.
Description and taxonomy
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.
Subspecies
Two subspecies are recognized:
- C. g. griseatus– Found on Luzon, Catanduanes, Sibuyan Island, Mindoro, Negros and Cebu
- C. g. mindanensis – Found on Mindanao; poorly known and no recent confirmed records, may possibly be a different species altogether.
Ecology and behavior
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.
Habitat and conservation status
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]
