The Blyth's Hornbill (Rhyticeros plicatus) is also known as Papuan Hornbill. Its local name in Tok Pisin is kokomo. It is a large hornbill species inhabiting the forest canopy in the Wallacea and Melanesia.

Previously, this hornbill was placed in the genus Aceros. It has in the past been often lumped with the Plain-pouched Hornbill (R. subruficollis), and sometimes considered to include the Narcondam Hornbill (R. narcondami) and the Wreathed Hornbill (R. undulatus) as subspecies.

This is a list of the bird species recorded in the Solomon Islands. The avifauna of the Solomon Islands, including the island of Bougainville (to Papua New Guinea) includes a total of 289 species, of which 71 are endemic, 3 have been introduced by humans, and 39 are rare or accidental. 26 species are globally threatened.

This list's taxonomic treatment (designation and sequence of orders, families, and species) and nomenclature (common and scientific names) follow the conventions of Clements's 5th edition. The family accounts at the beginning of each heading reflects this taxonomy, as do the species counts found in each family account. Introduced and accidental species are included in the total counts for the Solomon Islands.

The following tags have been used to highlight certain relevant categories. The commonly occurring, native, species do not fall into any of these categories.

Order: Podicipediformes Family: Podicipedidae

Grebes are small to medium-large sized freshwater diving birds. They have lobed toes, and are excellent swimmers and divers. However, they have their feet placed far back on the body, making them quite ungainly on land. There are 20 species worldwide and 2 species which occur in the Solomon Islands.

Order: Procellariiformes Family: Procellariidae

The fauna of New Guinea comprises a large number of species of mammals, reptiles, birds, fish, invertebrates and amphibians.

As the world’s largest and highest tropical island, New Guinea occupies less than 0.5% of world's land surface, yet supports a high percentage of global biodiversity. Approximately 4,642 vertebrate species inhabit the island of New Guinea and its surrounding waters, which constitutes about 8% of the recognized world vertebrates. This ranges from an estimated 4% of the world's lizards and mammals, to about 10% of the world's fish species.

The numbers of global and New Guinea invertebrate species are poorly known, and thus an accurate comparison is difficult. Butterflies are the best known invertebrate group, and are represented in New Guinea by about 735 species, which is about 4.2% of the world total of 17,500 species.
