Acrocephalus longirostris

Appearance
It has two color morphs. A light morph that is pale yellow with mottled brownish above, and an olive-brown dark morph.

Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Habits
Perching birds hold with three toes forward and one back. A named island starling or leafbird in this catalog is a wild population, not a cage type.
In crisis
It was last seen in 1987, and was previously feared to have gone extinct due to habitat destruction by hydroelectric power, road-building, and exploitation of bamboo, as well as the introduction of the invasive species such as the miconia tree, the common myna, and the feral cat. A 2018 study recommended downlisting the species from Critically Endangered or possibly extinct to just Critically Endangered.
