Oʻahu ʻelepaio

provided by wikipedia EN

The Oʻahu ʻelepaio (Chasiempis ibidis) is a monarch flycatcher found on the Hawaiian Island of Oahu.

Taxonomy and systematics

The Oʻahu ʻelepaio was formerly considered as a subspecies of the Hawaii ʻelepaio until reclassified as a separate species in 2010.[2]

Description

This species looks very similar to the Hawaiʻi ʻelepaio, but the white underside extends to the flanks and further up the breast, and the upperside - especially the head - is more rust-colored.

Threats

Avian malaria and fowlpox are widespread in the population and although it appears to have weathered the worst of it, it is threatened by a combination of these diseases and predation of nestlings, eggs and adult females by rats. In areas where rats are controlled, survival and nest success are higher.

Status

It is now restricted to an area of 47 square kilometers (18 sq mi) in the Koʻolau and Waiʻanae ranges, where a fragmented population of 1,200-1,400 birds occurs. It is listed as endangered. Recently completed surveys of populations in the Koʻolau range have unexpectedly revealed that the population has largely remained stable since surveys conducted in the 1990s. However, only about 20 individuals are left on the windward side of the Koʻolau range, with some valleys containing only a single ʻelepaio. Without intervention, this population faces extirpation in the near future due to small population phenomena.

Chasiempis ibidis ( Spanish; Castilian )

provided by wikipedia ES

El monarca de Oahu o elepaio de Oahu (Chasiempis ibidis) es una especie de ave paseriforme de la familia Monarchidae nativo de la isla hawaiana de Oahu. Ahora está restringido a un área de 47 kilómetros cuadrados en las cordilleras de Koʻolau y Waiʻanae, donde se reproduce en una población fragmentada de 1200-1400 aves.

Conservación

La especie está catalogada como en peligro de extinción, la malaria aviar y la viruela aviar están extendidas en la población y aunque parece haber resistido la peor parte, se ve amenazada por una combinación de estas enfermedades y la depredación de pichones, huevos y hembras adultas por las ratas. En las áreas donde se han controlado las ratas, la supervivencia y el éxito de los nidos es más alto. Encuestas recientes en las poblaciones de Koʻolau han revelado de forma inesperada que la población se ha mantenido prácticamente estable desde las encuestas realizadas en la década de 1990. Sin embargo, solo alrededor de 20 individuos quedan en el barlovento de la cordillera de Koʻolau, algunos valles contienen un único ejemplar. Sin intervención, esta población se enfrenta a la extirpación en un futuro próximo debido a los pequeños fenómenos poblacionales.

Vogels

De Oahu-elepaio (Chasiempis ibidis) is een vogelsoort uit het geslacht Chasiempis uit de familie monarchen en waaierstaartvliegenvangers (Monarchidae), een familie van oscine zangvogels. De De Oahu-elepaio is een inheemse soort op Oahu het dichtst bevolkte eiland van Hawaï. Sinds 2010 wordt de vogel door gezaghebbende organisaties zoals de American Ornithologists' Union als een aparte soort beschouwd; daarvoor was het de ondersoort Chasiempis sandwichensis ibidis.

Natuurbescherming

De Oahu-elepaio is een bedreigde soort waarvan in 2005 nog maar 1200 tot 1400 individuen bestaan die leven in een verbrokkeld habitat in verschillende deelpopulaties. De vogels worden bedreigd door een vogelziekte die verspreid wordt door geïmporteerde steekmuggen.[2]
