The souimanga sunbird (Cinnyris sovimanga) is a small passerine bird of the sunbird family, Nectariniidae. It is native to the islands of the western Indian Ocean where it occurs on Madagascar, the Aldabra Group and the Glorioso Islands.

Taxonomy

The souimanga sunbird was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae . He placed it with the tree-creepers in the genus Certhia and coined the binomial name Certhia sovimanga. [2] The specific epithet sovimanga comes from a French name for the bird, Souï-manga. [3] Gmelin based his account on "Le grimpereau violet de Madagascar" that had been described and illustrated in 1760 by the French zoologist Mathurin Jacques Brisson and Le Soui-Manga that had been described in 1778 by the Comte de Buffon. [4] [5] The souimanga sunbird is now placed in the large genus Cinnyris that was introduced in 1816 by the French naturalist Georges Cuvier. [6]

Five subspecies are recognised: [6]

The subspecies C. s. abbotti was formerly sometimes treated as a separate species, Abbott's sunbird (Cinnyris abbotti). [6] [7]

Description

The souimanga sunbird is 10 centimetres (3.9 in) long with a wingspan of 13 centimetres (5.1 in). [8] The black bill is long, thin and curved. Males of the nominate subspecies have a metallic green head, back and throat. The breast is blackish with a more or less continuous red band while the belly is yellow and the wings and tail are brown. There are yellow tufts at the sides of the breast which become visible when the birds lift their wings in courtship display. Males presumably moult into a duller eclipse plumage by March–April, [9] losing most of the metallic and red feathering for a few months. Females have grey-brown upperparts, a dull yellow belly and a grey throat and breast with darker markings. Juveniles are similar to the adult females but the chin and throat are sometimes black and the upperparts may be more olive. [8]

Subspecies C. s. abbotti is larger - 11 centimetres (4.3 in) long with a 14 centimetres (5.5 in) wingspan. The males have a broader red breastband and there is no yellow on the underparts which are dark brown (ssp. abbotti) or blackish (ssp. buchenorum). [8]

Male birds of the nominate group have wings of c.50–58 millimetres (2.0–2.3 in), tails of c.31–41 millimetres (1.2–1.6 in) and 20–25 millimetres (0.79–0.98 in) long bills. Females measure 10% less. [9]

This bird has a chirruping flight call and a loud, hoarse alarm call. Only the male sings; a fast and scratchy song with frequently repeated phrases.

Behaviour and ecology

Together with the Malagasy white-eye and the Madagascar cisticola, souimanga sunbirds are the most common small landbirds across much of their range; [9] [10] ample stocks of the present species and the white-eye exist in the maybe 4 square kilometres (1.5 sq mi) of habitat in the Glorioso Islands. The IUCN considers it a species of least concern.

The souimanga sunbird can be found in a variety of habitats from mountain forests to mangroves and scrubland as well as in parks, gardens and other human-modified ecosystems. They use their curved bill to probe flowers for nectar and also feed on insects and spiders. They have few natural enemies and their nests are inaccessible to most predators.

Breeding

The long breeding season lasts from August to March on Aldabra at least. [9] The nest is dome-shaped and has an entrance hole on the side. It is made of plant material such as grass stems, coconut fibre and leaves. It is usually suspended from a branch about 1 to 2 metres (3 ft 3 in to 6 ft 7 in) above the ground but may be built on a building or in a sinkhole within eroded coral. Two eggs are laid and are incubated for 13 to 14 days; they are whitish with reddish mottling. The young birds fledge after 16 to 18 days. Nest-building and incubation of the eggs are done by the female who also plays a greater role than the male in feeding the chicks.

Seychelles is a small island country east of the African continent located in the Sea of Zanj due north of Madagascar, with Antsiranana as its nearest foreign city. Seychelles lies between approximately 4ºS and 10ºS and 46ºE and 54ºE. The nation is an archipelago of 155 tropical islands, some granite and some coral. the majority of which are small and uninhabited. The landmass is only 452 km2 (175 sq mi), but the islands are spread wide over an exclusive economic zone of 1,336,559 km2 (516,048 sq mi). About 90 percent of the population of 100,000 live on Mahé, 9 percent on Praslin and La Digue. Around a third of the land area is the island of Mahé and a further third the atoll of Aldabra.

Aldabra is the world's second-largest coral atoll, lying southeast of the continent of Africa. It is part of the Aldabra Group of islands in the Indian Ocean that are part of the Outer Islands of the Seychelles, with a distance of 1,120 km (700 mi) southwest of the capital, Victoria on Mahé Island. Initially named by Arab seafarers for its harsh environment, Aldabra became a French colony dependency in the 18th century, leading to the exploitation of its natural resources, particularly giant tortoises. After passing through British hands, Aldabra faced potential military use in the 1960s, but international protests resulted in its protection. The atoll boasts unique geography, featuring the world's largest raised coral reef and a large shallow lagoon. Aldabra's history involves human impact, including failed agricultural ventures.

The garden sunbird, previously known as the olive-backed sunbird, is a species of passerine bird in the family Nectariniidae that is found in the Philippines except on the Palawan island group. It was formerly considered to be conspecific with seven other species: the ornate sunbird, Palawan sunbird, Sahul sunbird, Tukangbesi sunbird, Flores Sea sunbird, South Moluccan sunbird and the Mamberamo sunbird. It is a small, brightly coloured bird with olive-green plumage on the wings and back with a bright yellow chest. It has a long downward-curved bill it uses for taking nectar and capturing insects. It is primarily nectarivorous, but will take insects and spiders, particularly when feeding chicks.

Named after Joan Gideon Loten, who was the Dutch governor of colonial Ceylon, it is very similar to the purple sunbird that is found in the same areas and also tends to hover at flowers for nectar, but can be distinguished by the longer bill, the maroon band on the breast and brownish wings. Like other sunbirds, it is also insectivorous and builds characteristic hanging nests.

The Aldabra fody is a passerine bird in the family Ploceidae. It is endemic to Aldabra, an atoll northwest of Madagascar, part of Seychelles. Regarded as conspecific with the Comoros fody in the past, it is now recognized as a distinct species by the International Union for the Conservation of Nature (IUCN). Both sexes are yellow in color across much of the body, with breeding males orange-scarlet on the head and neck. The species has a large and powerful bill, used to compete with other birds of Aldabra for food. Nesting occurs over several months, often in introduced coconut palms and Casuarina trees. The Aldabra fody is considered endangered by the IUCN, threatened by predation of nests and drought. Hybridization with the related Madagascar fody has occurred in the past, but is not currently considered a danger to the species.
