Black-cheeked Warbler

Large and social starling of fields, parks, and farmland. Adult’s contrastingly and sharply demarcated white head in both sexes is unique amongst the region's starlings. Females are duller than males, but both have gray bodies and dark wings with a white patch. Juveniles are brown overall with a pale face. Gathers in immense roosts in the winter, often with White-cheeked Starlings. Noisy, often giving harsh and ear-splitting calls, particularly when flying in to roost.

A highly variable species that seemingly changes its appearance on every island. Generally green or blue above and white or buffy orange below. Most subspecies have some degree of orange or buff eyebrow, most notably lacking in the Vanikoro Island population. In Tonga and Samoa, birds are much whiter, with a broad white eyebrow bordering a small greenish cap and a clean white underside. Generally coastal, preferring mangroves, but common in most habitat types to 1500 meters of elevation. Sacred Kingfisher is very similar but has a slimmer bill and is always buff below. Juvenile Sacred Kingfisher has a more scaly breast. Pacific’s most common call is a loud, harsh “kee-kee-kee-kee” often given in flight.

Very small grayish-brown flycatcher, with brighter orangey color on the face and forehead. Occurs in dry areas and pastures with scattered trees and bushes where it mostly forages near the ground and is typically difficult to spot. It is very noisy, emitting squeaky “plee-plit-irick” calls, sometimes in a duet. Occurs in western Ecuador and northwestern Peru.
