The Comoro olive pigeon (Columba pollenii), also known as the Comoros Rameron pigeon or simply the Comoro pigeon, is a species of bird in the family Columbidae. It is found in Comoros and Mayotte. It is becoming rare due to habitat loss.
Easily distinguishable from other pigeon species, the Comoros olive pigeon is the largest bird in the Comoro Islands. [2] It has a dark plumage. Adolescent pigeons have a bright yellow bill, whereas older ones have a dull green or brown bill. The Comoros olive pigeon makes a very deep coo of "guk-ohoooo hoo hooo". [3]
Its natural habitat is subtropical or tropical moist montane forests and it can be found in Comoros (especially Mount Karthala) and Mayotte, with a higher-density population being observed in the latter. [3]
Although described as locally common in parts of Grand Comoro, the Comoros olive pigeon is in general a fairly scarce bird with a small total population. The chief threat it faces is the clearance of the forest habitat in which it lives, but it is also hunted on each of the four islands on which it is found. The population trend is unknown, but the total population is probably fewer than 10,000 individuals, and the International Union for Conservation of Nature has assessed its conservation status as "near threatened". [1]
The Comoros archipelago consists of four main islands aligned along a northwest–southeast axis at the north end of the Mozambique Channel, between Mozambique and the island of Madagascar. Still widely known by their French names, the islands officially have been called by their Swahili names by the Comorian government. They are Grande Comore (Njazidja), Mohéli (Mwali), Anjouan (Nzwani), and Mayotte (Mahoré). The islands' distance from each other—Grande Comore is some 200 kilometers from Mayotte, forty kilometers from Mohéli, and eighty kilometers from Anjouan—along with a lack of good harbor facilities, make transportation and communication difficult. Comoros are sunny islands.
The trocaz pigeon, Madeira laurel pigeon or long-toed pigeon is a pigeon which is endemic to the island of Madeira, Portugal. It is a mainly grey bird with a pinkish breast; its silvery neck patch and lack of white wing markings distinguish it from its close relative and probable ancestor, the common wood pigeon. Its call is a characteristic six-note cooing, weaker and lower-pitched than that of the wood pigeon. Despite its bulky, long-tailed appearance, this pigeon has a fast, direct flight.
The pink pigeon is a species of pigeon in the family Columbidae endemic to Mauritius. The pink pigeon nearly became extinct in the 1970s and the 1990s and is still very rare. It is the only Mascarene pigeon that has not become extinct. It was on the brink of extinction in 1991 when only 10 individuals remained, but its numbers have increased due to the efforts of the Durrell Wildlife Conservation Trust since 1977. While the population remains at below 500 birds as of 2011, the IUCN downlisted the species from Critically endangered to Endangered on the IUCN Red List in 2000, and then downlisted it again to Vulnerable in 2018.
The lemon dove or cinnamon dove is a species of bird in the pigeon family Columbidae found in montane forests of sub-Saharan Africa. The São Tomé lemon dove is usually treated as a subspecies. The lemon dove has a generally brownish-grey plumage with a cinnamon brown breast. Males have a greenish-glossed neck and white markings on the head, and females and juveniles are rather more brown and have grey facial markings. This dove is a common species, and the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
The African olive pigeon or Rameron pigeon is a pigeon which is a resident breeding bird in much of eastern and southern Africa from Ethiopia to the Cape. Populations also are found in western Angola, southwestern Saudi Arabia and northern Yemen. It is locally common, although sizeable gaps in its distribution occur due to its habitat requirements.
The Malagasy harrier is a bird of prey belonging to the marsh harrier group of harriers. It inhabits Madagascar and the Comoro Islands in the Indian Ocean. It was formerly regarded as a subspecies of the Réunion harrier but is increasingly treated as a separate species. It is also known as the Madagascar harrier, Madagascar marsh harrier or Malagasy marsh harrier.
Humblot's flycatcher or the Grand Comore flycatcher, is a small passerine bird belonging to the Old World flycatcher family. It is the only member of its genus. Humblot's flycatcher is endemic to the island of Grand Comoro in the Comoros where it inhabits forest on the slopes of Mount Karthala. The scientific name commemorates the French naturalist Léon Humblot.
The Comoro blue pigeon is a species of bird in the family Columbidae. It is endemic to the Comoros and the coralline Seychelles. It is rated as a species of near threatened on the International Union for Conservation of Nature Red List of Endangered Species.
The island bronze-naped pigeon, also known as the São Tomé bronze-naped pigeon or São Tomé pigeon, is a species of bird in the pigeon family, Columbidae. It is endemic to the Gulf of Guinea, where it is found on the islands of São Tomé, Príncipe, and Annobón. It inhabits rainforest, secondary forests, and plantations at elevations of up to 1,668 m (5,472 ft), although it is more common at lower elevations. A small, darkish pigeon, it has a total length of 28 cm (11 in). Adult males have slate-grey heads and upper backs, blackish-grey wings, backs, and tails, buffy-white throats, ashy-grey breasts and bellies, and rufous vents. The back of the neck and upper back are glossy pink or green, while the wings have a green tinge to them. Females are similar, but have browner undersides, duller and less glossy upperparts, and more rusty-orange outer tail feathers.
The Wetar ground dove is a species of bird in the family Columbidae found on Wetar, Indonesia, and on Timor. Its natural habitats are monsoon forests and gallery forests, and possibly woodland and bamboos. Threatened by habitat loss and hunting, the species is assessed as endangered by the IUCN.
The Malagasy turtle dove or Madagascar turtle dove is a bird species in the pigeon and dove family, Columbidae. It is found in Mauritian-Indian Ocean Territory, the Comoros, Madagascar, Mauritius, Mayotte, Réunion, and the Seychelles.
The Madagascar green pigeon or Madagascan green pigeon is a species of bird in the family Columbidae. It is found in Madagascar, Comoros, and Mayotte. The taxon griveaudi, by most authorities considered a subspecies of the Madagascan green pigeon, is sometimes considered a separate species, the Comoros green pigeon. Its natural habitats are subtropical or tropical dry forest and subtropical or tropical moist lowland forest.
The black cuckoo-dove, also known as the slaty cuckoo-dove, is a species of bird in the family Columbidae. It is endemic to the Lesser Sunda Islands, being found on Timor, Wetar, Rote, and Atauro. It inhabits primary and secondary monsoon forest, eucalyptus forest, and woodlands. It is 38.5 cm (15.2 in) long on average and is mainly dark bluish-gray, lighter on the head and underparts and darker on the wings and tail. It has yellow orbital skin.

The Comoros forests is a terrestrial ecoregion which covers the Comoro Islands, which lie in the Mozambique Channel between Madagascar and East Africa. These include four main islands: Grande Comore, Anjouan and Mohéli, of the Union of the Comoros, and Mayotte, a department and region of France.
Mont Choungui is a distinctively conical volcanic mountain in the southern part of the French island of Mayotte, in the Comoro archipelago of the western Indian Ocean. It is the second highest point of the island at 593 m (1,946 ft), the highest being Mont Bénara, and is visible from far out at sea.
