Distribution

Region

Central Philippines (Visayas)

Typical Environment

Primarily inhabits montane and mossy evergreen forests on Negros Island, using the midstory and canopy to glean small arthropods. It also occurs along forest edges, in secondary growth near intact forest, and in ravines with dense understory. The species is most frequently encountered in relatively undisturbed highland forest, where it often forages with mixed-species flocks. It avoids open, heavily degraded habitats. Nesting is typically within dense vegetation or low trees in secluded forest patches.

Useful to know

The Negros leaf warbler is a small, active insect-hunter that flits through foliage, often joining mixed-species flocks. It favors montane forests on Negros Island in the central Philippines and was once grouped within the broader 'Old World warblers.' Its thin, high-pitched song can be hard to localize in dense vegetation. Continued forest loss on Negros makes intact high-elevation habitats especially important for this species.

Behaviour

Temperament

active and alert

Flight Pattern

short rapid wingbeats

Social Behavior

Usually seen singly, in pairs, or small family groups, and frequently joins mixed-species flocks in the canopy. Builds a small cup nest concealed in dense foliage or low trees. Both parents typically attend and feed the young. Territorial singing increases during the breeding season.

Migratory Pattern

Song Description

A series of thin, high-pitched whistles and trills that can seem ventriloquial in dense forest. Calls include short, sharp tsip notes given during foraging and flocking.

Negros scops owl

The Negros scops owl, 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 has a distinct and striking rufous or reddish brown crown, nape and face. It was formerly classified as a subspecies of the Philippine scops owl. It is threatened by habitat loss and hunting for the pet trade.

Nelicourvi weaver

The nelicourvi weaver is a species of bird in the family Ploceidae. It is endemic to Madagascar. Together with its closest relative, the sakalava weaver, it is sometimes placed in a separate genus Nelicurvius. A slender, sparrow-like bird, it is 15 cm (5.9 in) long and weighing 20–28 g (0.71–0.99 oz). Breeding males have a black bill and head, brown eyes, yellow collar, grey belly, chestnut-brown lower tail coverts, olive back, and blackish flight feathers edged greenish. Non-breeding males have mottled grey and green heads. In the breeding female the front of the head is yellow and the back olive green, with a broad yellow eyebrow. It builds solitary, roofed, retort-shaped nests, hanging by a rope from a branch, vine or bamboo stem, in an open space. It primarily feeds on insects, looking on its own or in very small groups, often together with long-billed bernieria. Its natural habitat is subtropical or tropical moist lowland and mountain forests. The conservation status of Nelicourvi weaver is least concern according to the IUCN Red List.

Neotropic cormorant

The neotropic cormorant or olivaceous cormorant is a medium-sized cormorant found throughout the American tropics and subtropics, from the middle Rio Grande and the Gulf and Californian coasts of the United States south through Mexico and Central America to southern South America, where it is called by the indigenous name of biguá. It also breeds in the Bahamas, Cuba, and Trinidad. It can be found both on coasts and in inland waters. There are at least two subspecies: N. b. mexicanum from Nicaragua northwards and N. b. brasilianum further south. In Peru, the neotropic cormorant is used by the Uru people for fishing.
