Taxonomía

The duchess lorikeet was formally described in 1879 by the English clergyman and ornithologist Henry Baker Tristram from a specimen collected at Makira Harbour, San Cristoval, Solomon Islands. Tristam coined the binomial name Charmosyna margarethae. The specific epithet was chosen to honour Princess Louise Margaret of Prussia who became the Duchess of Connaught and Strathearn when she married Queen Victoria's son Prince Arthur in 1879. The lorikeet was moved to its own genus, Charmosynoides, based on a molecular phylogenetic study published in 2020. The name Charmosynoides is a combination of the genus name Charmosyna with the Ancient Greek -oides meaning "resembling".

Distribución y hábitat

The species is found only on Bougainville Island and 6 islands in the Solomon Islands. It is a localised species that is absent from large areas of habitat in its range that are potentially suitable for it. It is most often found in lower montane forest and in coconut plantations. It is found from sea level to an elevation of 1,350 m (4,430 ft) asl. It may be nomadic and inhabit habitats at different altitudes.

Comportamiento

The calls of the duchess lorikeet are generally more squeaky than that of other species of lorikeets. Their flight calls are loud and high-pitched, while high-pitched screek notes are made while feeding.<p>The lorikeet mostly feed on nectar, pollen, and small fruits, especially Schefflera.<p>Much of the lowland forest in its range is scheduled to be logged, although it could survive at higher altitudes. Another threat to the species is the possibility of large scale pet trade.
