Caroline Reed Warbler Acrocephalus syrinx

Medium-sized drab brown endemic of Micronesia’s Caroline Islands, where it inhabits a range of habitats, from native forest to degraded coastal scrub and patches of tall grass. Capable of persisting on even tiny coral atolls if there is sufficient vegetation. Often forages in dense bushes or grasses, but also ventures onto the ground and into the treetops. Song is a rather pleasant series of whistles, warbles, trills and chatters, often with repeating notes.
