Cockerell's Fantail

Cockerell's fantail (Rhipidura cockerelli) is a lively, medium-sized flycatcher in the family Rhipiduridae, endemic to the Solomon Islands archipelago in the southwestern Pacific Ocean. Like other fantails, it is characterised by its habit of fanning and cocking its long tail while foraging aerially and among vegetation for small flying insects and other arthropods. The species occupies primary and mature secondary lowland and hill forest on several islands within the Solomon group, where it typically inhabits the middle and lower forest strata, often joining mixed-species foraging flocks. Males and females are similarly plumaged in shades of rufous, brown, and black, with the distinctive white brow stripe common to many Solomon Islands fantails. Rhipidura cockerelli is classified as Least Concern by the IUCN, reflecting adequate forest cover across much of its range and the relative remoteness of many of the islands it inhabits. However, growing pressure from logging, agricultural conversion, and human settlement in the Solomon Islands poses potential longer-term risks to forest-dependent species like this fantail. The species has no presence in Norway; database listings to that effect represent a data artifact. Its distribution is confined entirely to the Solomon Islands chain. The species was named after the British entomologist and naturalist T.D.A. Cockerell, who contributed extensively to natural history collections from the Pacific during the late nineteenth and early twentieth centuries.

Green Sea Turtle

The green sea turtle is one of the largest sea turtles. They are named for the green color of their cartilage and fat, not their shells.
