Rimbeak

Rimbeak is a small passerine bird described in field guides of the Rimblade Archipelago, a chain of islands in a temperate coastal region. It has a distinctive curved beak that is ivory to pale yellow toward the tip, and plumage that is slate-gray on the crown and back with a pale underside. The wings are short and rounded, and the tail is of medium length.

Size is about 12 to 13 centimeters in length, with little sexual dimorphism; adults maintain their plumage year-round, while juveniles appear duller with faint markings on the throat.

Distribution and habitat: Rimbeak is endemic to the Rimblade Archipelago, where it inhabits coastal forests, mangroves, and scrub on several islands. It is most common from sea level up to about 400 meters and tends to favor fruiting shrubs and patches with tubular flowers.

Behavior and diet: The species forages in the mid to upper canopy, feeding on nectar, fruit, seeds, and small invertebrates. It often forms small loose flocks outside the breeding season and participates in soft, high-pitched calls and, at times, a short duet with others.

Reproduction: The breeding season extends from early spring to early summer. Nests are cup-shaped and placed in shrubs or understory trees. Clutch size ranges from two to four eggs, with both parents incubating and feeding the chicks. Eggs are typically bluish-white with light brown speckles.

Conservation and notes: There is no formal global assessment for Rimbeak. Within its range it is considered locally common, but habitat loss from coastal development and mangrove clearance could threaten localized populations.
