The Negros scops owl (Otus nigrorum), also known as the Visayan scops owl, is an owl, endemic to the islands of Negros and Panay in the Philippines, belonging to the family of the typical owls Strigidae. It was formerly classified as a subspecies of the Philippine scops owl. It is threatened by habitat loss and hunting for the pet trade.
EBird describes the bird as "A fairly small owl of lowland and foothill forest on the islands of Negros and Panay, where it is the only scops-owl. Dark brown above and pale gray below, with a rufous face bordered with a black line and a pale gray V-shape between the eyes. Occurs together with Luzon boobook, but Negros Scops-Owl has orange rather than yellow eyes and lacks the brown-streaked chest. Song is a descending series of upslurred yelps." [3]
It is the smallest and palest of the endemic Philippine scops owl complex. [4]
Negros scops owls prey at night on insects. They live alone or in monogamous pairs. They breed throughout the year, laying clutches of 1 or 2 eggs. They nest in tree hollows in forests of the Philippine lowlands. [4]
Its natural habitats are tropical moist lowland and montane primary and secondary forest up to 1,000 meters above sea level. [4] While they can tolerate secondary forest, they have the highest population densities and health in primary (old-growth) forest.
The IUCN Red List has assessed this bird as vulnerable with the population being estimated at 1,000 to 2,499 mature individuals. Its main threat is habitat destruction through both legal and Illegal logging, conversion into farmlands through slash-and-burn, charcoal burning, and mining. Habitat loss on both Negros and Panay has been extensive. By 2007, Negros and Panay had a 3% and 6% remaining forest cover with a huge chunk of this being in higher elevation forests where this bird does not thrive. Despite the already paltry numbers, these figures are still continuing to decline due to the above-mentioned threats.
There are currently no species-specific conservation plans. It occurs in a few protected areas in Northern Negros Natural Park, Mount Kanlaon National Park and Northwest Panay Peninsula Natural Park. However, as with most areas in the Philippines, protection from hunting and illegal logging is lax.
The Philippine scops owl is a common owl, endemic to the Philippines, belonging to the family of the typical owls Strigidae. Other common names include "Otus Whitehead", "Whitehead scops owl" and "Luzon lowland scops owl". Everett's scops owl and Negros scops owls were formerly considered conspecific but are now classified as separate species.
Walden's hornbill locally called dulungan, also known as the Visayan wrinkled hornbill, rufous-headed hornbill or writhe-billed hornbill, is a critically endangered species of hornbill living in the rainforests on the islands of Negros and Panay in the Philippines. It is closely related to the writhed hornbill, but can be recognized by the yellow throat and ocular skin in the male, and the blue throat and ocular skin in the female. Its binomial name commemorates the Scottish ornithologist Viscount Walden.
The Philippine eagle-owl is a vulnerable species of owl belonging to the family Strigidae. It is endemic to the Philippines, where it is found in lowland forests on the islands of Catanduanes, Samar, Bohol, Mindanao, Luzon, Leyte and possibly Sibuyan. The Philippine eagle-owl feeds on rodents and amphibians. Due to its reliance on living in large lowland forests, forest conservation is important in order to maintain populations of the Philippine eagle-owl, which is becoming increasingly vulnerable to going extinct. The Philippine eagle-owl was previously listed as endangered, but due to destruction of lowland habitat and possible hunting, the eagle-owl has since been adjusted to the vulnerability of extinction.
The Palawan scops owl is an owl endemic to the Philippines only being found on the island of Palawan. It is found on tropical moist lowland forest. It is threatened by habitat loss.
The Luzon scops owl or the Luzon highland scops owl is a species of scops owl endemic to Luzon, Philippines. Not to be confused with the Philippine scops owl, sometimes referred to as the Luzon lowland scops owl, which is a more common species that shares the same range. The Luzon scops owl, however, is smaller and inhabits higher altitudes than its lowland relative.
The Mindanao brown dove is a threatened species of bird in the family Columbidae. It is endemic to forests on the Philippine islands of Mindanao and Basilan, but it has not been recorded from the latter island since 1937. It is threatened by habitat loss and hunting. Until recently, it was considered conspecific with the Tawitawi brown dove and collectively called the dark-eared brown dove.
The white-winged cuckooshrike, also known as white-winged cicadabird or white-winged graybird, is a species of bird in the family Campephagidae. It is endemic to the Philippines found on the islands of Negros, Panay and formerly on Guimaras. Some taxonomists place this species in the genus Analisoma.
The flame-templed babbler is a species of bird of the family Zosteropidae, in the genus Dasycrotapha. It is one of the most remarkable and distinctive birds with its complex head markings with orange crown tufts, black ears and yellow beak and face. It is endemic to the Philippines, where it is found on the islands of Panay and Negros. Its natural habitat is tropical moist lowland forest. It is threatened by habitat loss. Along with the Negros striped babbler, it is one of the two babbler species extremely sought after by birdwatchers on Negros.
The black-belted flowerpecker or Visayan flowerpecker, is a species of bird in the family Dicaeidae. It is endemic to the Philippines where it is restricted to Panay, Negros and Guimaras islands. It was formerly regarded as a subspecies of the more widespread red-keeled flowerpecker. Sometimes the name red-keeled flowerpecker is used for D. haematostictum and D. australe is then known as the red-sided flowerpecker.
The celestial monarch is a species of bird in the family Monarchidae, and one of the most attractive of all the monarch flycatchers, with its spectacular blue crest and large greenish-yellow wattle. It is endemic to the Philippines with its extant range being in Luzon, Samar, Mindanao Tawi-Tawi and Basilan and it being possibly extinct on Negros and Sibuyan Island. It is often observed in mixed flocks with other birds such as blue fantails, rusty-crowned babblers, rufous paradise flycatchers, both short-crested monarchs and black-naped monarchs and other small forest birds. Its natural habitat is tropical moist lowland forests up to 750 masl. It is one of the most sought after birds by birdwatchers in the Philippines and in the world.
