Distribution

Region

Cenderawasih Bay Islands

Typical Environment

Occurs throughout Numfor Island in lowland evergreen and semi-evergreen forest, secondary growth, and scrubby edges. It forages from understory to canopy but is most frequently seen in the mid-story and crowns of taller trees. The species adapts to lightly disturbed habitats, including gardens with mature trees, yet remains most common in forested tracts. Proximity to watercourses and forest edges can increase prey availability. It is absent from open, treeless areas.

Useful to know

The Numfor leaf warbler is a small Old World warbler restricted to Numfor (Noemfoor) Island in Indonesia’s Cenderawasih Bay. It is an active canopy gleaner that often joins mixed-species flocks in forests and edge habitats. Like many island endemics, it may be sensitive to habitat alteration, so intact lowland forest is important for its persistence.

Social Behavior

Often joins mixed-species flocks, moving restlessly through foliage while gleaning prey. Pairs defend small nesting territories during the breeding season and build domed or cup-like nests low in dense vegetation. Both adults typically participate in chick provisioning.

Numfor paradise kingfisher

The Numfor paradise kingfisher, also known as the cobalt paradise kingfisher, is a tree kingfisher endemic to the Indonesian island of Numfor off the northwestern coast of New Guinea. It is a common species, but the forests where it lives are being affected by logging and the IUCN has rated its conservation status as "near-threatened".

Oʻahu ʻakepa

The Oʻahu ʻākepa is an extinct species of ʻākepa that was endemic to the island of Oahu. It was commonly sighted throughout the 19th century. This brick red Hawaiian honeycreeper was found in the mountain peaks in densely forested areas. The females were mostly gray with a tinge of green. The birds had a slight crossbill just like the other Loxops species. It used its crossbill to open up buds in search for nectar and insects for it to eat. Its most common haunts were the ʻōhiʻa and koa forests that were filled with the many flowers and insects that this species liked to eat. The Oʻahu ʻākepa is one of three different species of ʻākepa that were spread by possible weather and migration. The movement of the species stopped causing the species to break into four branches. The first branch was the Hawaiian ʻākepa, a scarlet- red bird that lives only on the Big Island and may be the ancestor of the genus Loxops. Next is the Maui ʻākepa, which was found as fossils on all the islands of Maui Nui, but was historically seen on Maui. It is a grayish-orange bird that was the first of the ʻākepa species to disappear. Then came the Oʻahu ʻākepa, which is a brick-red color and was seen till around the 1900s when it became extinct. The last branch was the akeke‘e, a green bird that is only found on the island of Kauaʻi.
