Solomon Islands: Solomon Islands is a sovereign country consisting of six major islands and over 900 smaller islands in Oceania lying to the east of Papua New Guinea and northwest of Vanuatu and covering a land area of 28400 km2 .  The country's capital, Honiara, is located on the island of Guadalcanal.  The country takes its name from the Solomon Islands archipelago, which is a collection of Melanesian islands that also includes the North Solomon Islands (part of Papua New Guinea), but excludes outlying islands, such as Rennell and Bellona, and the Santa Cruz Islands.

Ionian Islands: The Ionian Islands (Modern Greek: Ιόνια νησιά, "Ionia nisia" ; Ancient Greek, Katharevousa: Ἰόνιοι Νῆσοι, "Ionioi Nēsoi" ; Italian: "Isole Ionie" ) are a group of islands in Greece.  They are traditionally called the Heptanese, i.e. "the Seven Islands" (Greek: Ἑπτάνησα, "Heptanēsa" or Ἑπτάνησος, "Heptanēsos" ; Italian: "Eptaneso" ), but the group includes many smaller islands as well as the seven principal ones.  As a distinct historic region they date to the centuries-long Venetian rule, which preserved them from becoming part of the Ottoman Empire, and created a distinct cultural identity with many Italian influences.  The Ionian Islands became part of the modern Greek state in 1864.  Administratively today they belong to the Ionian Islands Region except for Kythera, which belongs to the Attica Region.

Caracoles: The Caracol people are an ethnic people of mainly European/English-African-Caribbean descent, who have been concentrated in Northern Honduras (specifically, the Bay Islands) since the early 19th century.  They speak an English-based creole.  "Caracol" is a Spanish term that literally translates as conch, or snail shell; it associates the people of the Bay Islands to their environment and seafaring culture.  In its current usage, the term Caracol refers to all people born in the Bay Islands region and their descendants.  The region of the Bay Islands encompasses the three major islands of Roatán, Útila, Guanaja, and the smaller islands or keys.

Babuyan Islands: The Babuyan Islands ( ), also known as the Babuyan Group of Islands, is an archipelago in the Philippines, located in the Luzon Strait north of the main island of Luzon.  The archipelago consists of four major islands and their surrounding smaller islands.

Lemon-bellied white-eye: The lemon-bellied white-eye ("Zosterops chloris") is a species of bird in the family Zosteropidae.  It is endemic to Indonesia, where it occurs on a number of islands from the Sunda Strait to the Aru Islands.  It is present on several of the Lesser Sunda Islands as well as on parts of Sulawesi, as well as many smaller islands, but is absent from the larger islands of Borneo, Java, Sumatra and Timor.  Currently (May 2017), HBW describes five sub-species of lemon-bellied white-eye.  However, the extensive distribution of "Z. c. intermedius" (including S. Sulawesi, SE.  Sulawesi, C. Lesser Sundas and small islands in between) is likely to contain more than one reproductively isolated population (cf. "Z.c. intermedius" and "Z. c. flavissimus").
