The Philippine frogmouth (Batrachostomus septimus) is a nocturnal bird that can be found throughout the Philippine archipelago. It is common in lowland forests and maturing second growth. There is little information about the bird. It feeds on grasshoppers, cicadas, crickets and beetles.
Like all frogmouths, the Philippine frogmouth has large eyes for better night vision, a large flat bill for capturing insects, and cryptic plumage which allows them to be camouflaged while perched during the day. They are found in the Philippines, and can be confused with the Philippine Nightjar, which despite its similar shape has very different plumage.
The Philippine frogmouth is a medium frogmouth, being 24–26 cm long, with two color morphs (and intermediate phases); one is a chestnut rufous with deep rufous ground color, the other a lighter brown with buff and black barring. [2] Both morphs have three distinct light buff or white bands; one on their hindneck, a second on their lower throat, and a third around the lower breast. They have a yellow-orange iris and brown feet and bill. Although males and females have a similar appearance, females are typically darker and plainer. [3]
The Philippine frogmouth is a sedentary bird, endemic to the Philippines, and is widely distributed within the archipelago, though noticeably absent from Palawan. Though rare, there have been sightings in India and Australia. They are thought to be found in lowland and maturing (but not mature) second growth forests, but their habitat is not known in detail as they are only active at night and do not sing songs or have loud calls. [4] [3]
The nest is built from a horizontal branch that is placed two to five meters above ground. It is made from the parent's own downy feathers which is held in place using spider silk, moss and lichens. The female lays one egg per season. The male incubates the egg during the day and the female at night.
Philippine frogmouths are adaptable, and eat large insects, such as grasshoppers, cicadas, crickets, and beetles. They feed by waiting on low branches and striking when they notice an insect moving below. [4] Like other species in the genus Batrachostomus, the Philippine frogmouth has elongated bristles around the base of their bill, believed to protect their eyes from prey. [5]
Male calls are a series of low, deep woah, wash, Guam, or g-aw noises, or a short even trill. [3] Female calls are louder, a short mewl that descends in pitch. Both sexes have a harsh growling call they repeat several times per minute, and a harsh staccato-like scream that is believed to be an alarm call. [6]
The Philippine frogmouth is currently listed as species of least concern by the IUCN as of 2012, though it is believed its population is slowly declining due to habitat destruction. The reason for this listing is the large range, the rate of decline not reaching the threshold to qualify as a vulnerable species, and while the population size has not been officially quantified, it is believed to exceed the threshold to be considered vulnerable based on the population size criterion. [1]
The frogmouths (Podargidae) are a group of nocturnal birds related to owlet-nightjars, swifts, and hummingbirds. Species in the group are distributed in the Indomalayan and Australasian realms.
The Sri Lanka frogmouth, Sri Lankan frogmouth or Ceylon frogmouth is a small frogmouth found in the Western Ghats of south India and Sri Lanka. Related to the nightjars, it is nocturnal and is found in forest habitats. The plumage coloration resembles that of dried leaves and the bird roosts quietly on branches, making it difficult to see. Each has a favourite roost that it uses regularly unless disturbed. It has a distinctive call that is usually heard at dawn and dusk. The sexes differ slightly in plumage.
The Indian nightjar is a small nightjar which is a resident breeder in open lands across South Asia and Southeast Asia. Like most nightjars it is crepuscular and is best detected from its characteristic calls at dawn and dusk that have been likened to a stone skipping on a frozen lake - a series of clicks that become shorter and more rapid. They are sometimes spotted on roads when their eyes gleam red in the spotlight of a vehicle. There is considerable plumage variation across its range and can be hard to differentiate from other nightjars in the region especially in the field.
The Australian owlet-nightjar is a nocturnal bird found in open woodland across Australia and in southern New Guinea. It is colloquially known as the moth owl. It is the most common nocturnal bird in Australia, and despite suffering from predation and competition by introduced species it is not considered threatened.
The tawny frogmouth is a species of frogmouth native to the Australian mainland and Tasmania and found throughout. It is a big-headed, stocky bird often mistaken for an owl due to its nocturnal habits and similar colouring.
The plain nightjar is a species of nightjar in the family Caprimulgidae. It breeds in the southern Sahel, Southern Sudan, the Horn of Africa and the southwestern Arabian Peninsula. It migrates to lower latitudes - including central Congo and northern Tanzania. A rather plain looking nightjar with grey-brown, brown, and rufous morphs. Males have white spots on primaries, large white corners to tail, and no white on the throat. Females have buffy-brown wing spots, and no white on the tail.
The rufous-cheeked nightjar is a species of nightjar in the family Caprimulgidae. It is an intra-African migrant that breeds in the south of its range. It spends the non-breeding season in eastern Nigeria, Cameroon, southern Chad and Sudan, the Republic of the Congo, the D.R.C. and western Central African Republic. Throughout the year it can be found in Southern Africa. It is a nocturnal species that feeds on flying insects, mainly hunting at dusk and the early night. They can hunt at night thanks to their large eyes that are adept at seeing in the dark. They cannot see in complete darkness and most likely cannot see colours either. The rufous-cheeked nightjar forms monogamous pairs and the egg laying period is from September to November. It looks very similar to other African nightjars and they are frequently misidentified during research and studies.
The silky-tailed nightjar is a species of nightjar birds in the family Caprimulgidae. It is found in Brazil, Argentina, Bolivia, Paraguay, and Peru. Its natural habitat is subtropical or tropical moist lowland forests.
The spotted nightjar or spotted eared-nightjar is a species of nightjar in the family Caprimulgidae. It inhabits much of mainland Australia and has also been found in several Indonesian islands. Its natural habitats are open forests and woodlands, scrub, spinifex and tussock grassland, savannah woodland and mangroves.
Blyth’s frogmouth is a species of bird in the family Podargidae. It was previously considered to be conspecific with the Javan frogmouth and Palawan frogmouth. The bird is a tropical species that ranges from India to Australia.
The large frogmouth is a species of bird in the family Podargidae. It is found in Brunei, Indonesia, Malaysia, and Thailand, in subtropical or tropical moist lowland forest. Logging of its habitat poses a risk to its survival, and the International Union for Conservation of Nature has listed it as being "near-threatened".
The Dulit frogmouth is a little-known species of bird in the frogmouth family, Podargidae, with a patchily recorded distribution in the mountain forests of northern and central Borneo to which it is endemic. The species is monotypic.
Hodgson's frogmouth is a species of bird in the family Podargidae. It is found in Bangladesh, Bhutan, China, India, Laos, Myanmar, Thailand, and Vietnam. Its natural habitat is temperate forests.
The Javan frogmouth, sometimes known as Horsfield's frogmouth, is a species of bird in the family Podargidae. It is sometimes considered conspecific with the Blyth's and Palawan frogmouths. Found in Southeast Asia, Indonesia and the Philippines, it lives in subtropical or tropical moist lowland forest.
The Sumatran frogmouth, also known as the short-tailed frogmouth and the pale-faced frogmouth, is a nocturnal bird belonging to the family Podargidae. It is endemic to the island of Sumatra in Indonesia.
Winchell's kingfisher or the rufous-lored kingfisher, is a species of bird in the family Alcedinidae, the kingfishers. It is endemic to the Philippines, its natural habitat being lowland forests. It is threatened by deforestation, and the International Union for Conservation of Nature (IUCN) has assessed it as a vulnerable species.
Antrostomus is a genus of nightjars formerly included in the genus Caprimulgus. They are medium-sized nocturnal birds with long pointed wings, short legs and short bills.
