Flightless bird of Tristan Da Cunha Island.



The Inaccessible Island Rail, (Atlantisia rogersi), is a small bird of the rail family, Rallidae. It is found only on Inaccessible Island in the Tristan Archipelago, and is notable for being the smallest extant flightless bird in the world. Unlike many other islands, Inaccessible Island has remained free from introduced predators, allowing this species to flourish while many other flightless birds, including the even smaller Stephens Island Wren, have perished.

This rail has an average weight of 30 grams and a length of 17 centimeters. It is dark rusty-brown above and dark grey below, with a short black bill and a red eye.

This rail is found throughout Inaccessible Island, but prefers grassland and open fern-bush. Its diet includes earthworms, moths, berries, and seeds.

A clutch of two eggs is laid between October and January; chicks are vulnerable to predation by the Tristan Thrush.

The Ascension Flightless Rail (Mundia elpenor) which disappeared some time before 1700 but was briefly mentioned and described by traveller and hobby naturalist Peter Mundy in 1656 and Aphanocrex podarces, the St Helena Swamphen which disappeared before 1600 and has never been encountered by scientists were once considered congeners of A. rogersi. As they are considered to have evolved independently (with A. podarces probably not even being closely related), they have each been moved to a separate genus. Both species became extinct due to predation by introduced species, mainly cats and rats.

Fiji 2009. Pigeons.



The Many-coloured Fruit-dove (Ptilinopus perousii) is a species of bird in the Columbidae family. It occurs on islands in the south-west Pacific Ocean where it is found in Fiji, the Samoan Islands, and Tonga. Its natural habitat is subtropical or tropical moist lowland forests. It usually feeds high in the canopy on fruit and berries, especially figs. The nest is a small platform of twigs where one white egg is laid.

It is a small dove, 23 cm in length. The male is mostly pale yellow-white with a red crown and red bar across the back. The female is mostly green, darker on the back and greyer on the head and breast. Her crown is red while the undertail-coverts are red in Samoan birds and yellow in birds from Fiji and Tonga.


The Purple-capped Fruit-dove (Ptilinopus porphyraceus), also known as the Crimson-crowned Fruit-dove (leading to easy confusion with the Beautiful Fruit-dove, alternatively known as the Crimson-capped Fruit-dove), is a species of bird in the Columbidae family. It is found in American Samoa, Fiji, Marshall Islands, Micronesia, Niue, Samoa, Tonga, and Wallis and Futuna Islands. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical mangrove forests.


The Whistling Dove, (Ptilinopus layardi) is a small fruit dove from Fiji. The species is endemic to the islands of Kadavu and Ono in the Kadavu Group in the south of Fiji. It is the most primitive of the "golden doves" a small subgroup of the genus Ptilinopus which includes two other small Fijian fruit doves, the Golden Dove and the Orange Dove. The group was once split into its own genus, Chrysoenas. The species has two other common names, the Velvet Dove and the Yellow-headed Dove.

The Whistling Dove is a small dove (20 cm) that is sexually dimorphic in its velvety plumage. The plumage of the male is dark green with a yellow head and undertail coverts, the female lacks the yellow plumage. They are difficult to see in the forest canopy, but can be found due to their distinctive whistling call, a clear rising whistle followed by a falling 'tinkle' (Pratt et al. 1987). The species feeds on fruits in the canopy.

The breeding of this species has not been studied much, a nest described in 1982 was a 'loose thin platform' constructed with twig-like vines 3m above the ground (Beckon 1982). When breeding only the female takes care of the young, an unusual adaption within the pigeon family. This difference in the levels of parental care has been suggested as an explnation of the sexual dimorphism in the golden doves. A single nestling was described.



The Orange Dove (Ptilinopus victor), also known as Flame Dove, is a small, approximately 20 cm (8 in) long, short-tailed fruit-dove in the family Columbidae. One of the most colorful doves, the male has a golden olive head and elongated bright orange "hair-like" body feathers. The golden-olive remiges are typically covered by the long orange wing coverts when perched. The legs, bill and orbital skin are bluish-green and the iris is whitish. The female is a dark green bird with blackish tail and orange-yellow undertail coverts. The young resembles female.

The Orange Dove is distributed and endemic to forests of Vanua Levu, Taveuni, Rabi, Kioa, Qamea and Laucala islands of Fiji. The diet consists mainly of various small fruits, berries, caterpillars and insects. The female usually lays one white egg.

The Orange Dove is closely related to the allopatric Whistling Dove and Golden Dove.

Birds of Vanuatu 1999.



The Chestnut-bellied Kingfisher (Todiramphus farquhari; also called Vanuatu Kingfisher) is a medium-sized kingfisher found only on the islands of Espiritu Santo, Malo and Malakula in Vanuatu.

It is dark blue above with richly-coloured orange underparts. There is a white spot in front of the eye and a broad black band on the side of the head. It has a white throat and collar. It measures 19-21cm in length and weighs 32-42 grams. The call is a series of loud, shrill, piping notes. The only other kingfisher in Vanuatu is the Collared Kingfisher which has paler blue-green upperparts, whiter underparts and a buff stripe above the eye.

The Chestnut-bellied Kingfisher mainly eats insects, especially beetles, and will also take spiders and small lizards. It usually hunts by perching on a branch and waiting for prey to appear. When it spots something it flies into the air or dives down to the ground or a tree trunk to catch it.

The nest is sometimes built in a hole in a palm tree or tree fern but usually a pair will excavate a burrow in a termite mound in a tree. They dig with their large bill and clear out material with their feet. After about fifteen days the burrow is completed and the termites seal off their sections. Three or four white eggs are laid. The breeding season is mostly from November to February with eggs laid in December.

The birds mainly inhabit dense rainforest in the interior of the islands, particularly above 200m. They are thought to be declining due to loss and degradation of the forest.



The Shining Bronze-Cuckoo (Chrysococcyx lucidus layardi Mathews, 1912) is a species of cuckoos in the Cuculidae family, found in Australia, Indonesia, New Caledonia, New Zealand, Papua New Guinea, Solomon Islands, and Vanuatu. It was previously also known as Chalcites lucidus.


The Peregrine Falcon (Falco peregrinus nesiotes Mayr, 1941)
The Peregrine's breeding range includes land regions from the Arctic tundra to the Tropics. It can be found nearly everywhere on Earth, except extreme polar regions, very high mountains, and most tropical rainforests; the only major ice-free landmass from which it is entirely absent is New Zealand. This makes it the world's most widespread bird of prey.[7] Both the English and scientific names of this species mean "wandering falcon", referring to the migratory habits of many northern populations.

While its diet consists almost exclusively of medium-sized birds, the Peregrine will occasionally hunt small mammals, small reptiles or even insects. It reaches sexual maturity at one year, and mates for life. It nests in a scrape, normally on cliff edges or, in recent times, on tall human-made structures.



The Rainbow Lorikeet, (Trichoglossus haematodus) is a species of Australasian parrot found in Australia, eastern Indonesia, Papua New Guinea, New Caledonia, Solomon Islands and Vanuatu. In Australia, it is common along the eastern seaboard, from Queensland to South Australia and northwest Tasmania. Its habitat is rainforest, coastal bush and woodland areas.


Rainbow Lorikeets travel together as pairs mostly and often pick up calls to fly as a flock, then dispersing again into pairs. Rainbow Lorikeet pairs defend their feeding and nesting areas aggressively against other Rainbow Lorikeets, and other bird species. They chase off not only smaller birds such as the Noisy Miner, but also larger and more powerful birds such as the Australian Magpie.

Although individual Rainbow Lorikeets are difficult to distinguish by their plumage they are possible to distinguish by their behaviour, size and eye colour differences at the very outside of the iris.
Rainbow Lorikeets feed mainly on pollen and nectar, and possess a tongue adapted especially for their particular diet. The end of the tongue is equipped with a papillate appendage adapted to collecting nectar from flowers. They are also frequent visitors at bird feeders that supply lorikeet-friendly treats, such as store-bought nectar, sunflower seeds, and fruits such as apples, grapes and pears.

In many places, including campsites and suburban gardens, wild lorikeets are so used to humans that they can be hand-fed. The Currumbin Wildlife Sanctuary in Queensland, Australia, is noted for its numerous lorikeets, which number in the thousands. Around 8am and 4pm each day the birds gather in a huge, noisy flock in the park's main area. Visitors are encouraged to feed them a specially-prepared nectar, and the birds will happily settle on arms and heads to consume it. Wild Rainbow Lorikeets can also be hand-fed by visitors at Lone Pine Koala Sanctuary in Brisbane, Queensland, Australia. Semi-tame lorikeets are common daily visitors in Sydney backyards, often by the dozens.

Fox Sparrow (Passerella iliaca).



The Fox Sparrow (Passerella iliaca) is a large American sparrow. It is the only member of the genus Passerella, although some authors split the genus into four species.

These birds forage by scratching the ground, which makes them vulnerable to cats and other predators, though they are generally plentiful. Fox sparrows birds migrate south on the west coast and to the eastern United States.

They mainly eat seeds and insects, as well as some berries. Coastal fox sparrows may also eat crustaceans.

House Sparrow (Passer domesticus).


The House Sparrow (Passer domesticus) is a member of the Old World sparrow family Passeridae, considered by some to be a relative of the Weaver Finch Family. It occurs naturally in most of Europe and much of Asia. It has also followed humans all over the world and has been intentionally or accidentally introduced to most of the Americas, sub-Saharan Africa, New Zealand and Australia as well as urban areas in other parts of the world. It is now the most widely distributed wild bird on the planet.


Yugoslavia 1982. Michel number: 1925.

This 14 to 16 cm long bird is abundant in temperate climates, but not universally common, and is scarce in many hilly districts. In cities, towns and villages, even around isolated farms, it can be the most abundant bird.

The male House Sparrow has a grey crown, cheeks and underparts, black on the throat, upper breast and between the bill and eyes. The bill in summer is blue-black, and the legs are brown. In winter the plumage is dulled by pale edgings, and the bill is yellowish brown. The female has no black on head or throat, nor a grey crown; her upperparts are streaked with brown. The juveniles are deeper brown, and the white is replaced by buff; the beak is pink to dull yellow. The House Sparrow is often confused with the smaller and more slender Tree Sparrow, which, however, has a chestnut and not grey crown, two distinct wing bars, and a black patch on each cheek.



Yugoslavia 1982. Michel number: 1926.

The House Sparrow is gregarious at all seasons in its nesting colonies, when feeding and in communal roosts. Although the Sparrows' young are fed on the larvae of insects, often destructive species, this species eats seeds, including grain where it is available.
In spring, flowers — especially those with yellow colours — are often eaten; crocuses, primroses and aconites seem to attract the house sparrow most. The bird will also hunt butterflies.
The Sparrow's most common call is a short and incessant chirp. It also has a double call note phillip which originated the now obsolete name of "phillip sparrow". While the young are in their nests, the older birds utter a long churr. At least three broods are reared in the season.
The common, but declining House Sparrow was the most common garden bird in 2006, calculated by the Royal Society for the Protection of Birds (RSPB).



Estonia 2002. Michel number: 430.

The nesting site is varied; under eaves, in holes in masonry or rocks, in ivy or creepers on houses or banks, on the sea-cliffs, or in bushes in bays and inlets. When built in holes or ivy, the nest is an untidy litter of straw and rubbish, abundantly filled with feathers. Large, well-constructed domed nests are often built when the bird nests in trees or shrubs, especially in rural areas.

The House Sparrow is quite aggressive in usurping the nesting sites of other birds, often forcibly evicting the previous occupants, and sometimes even building a new nest directly on top of another active nest with live nestlings. House Martins, Bluebirds, and Sand Martins are especially susceptible to this behavior. However, though this tendency has occasionally been observed in its native habitats (particularly concerning House Martins), it appears to be far more common in habitats in which it has been introduced, such as North America.

Five to six eggs, profusely dusted, speckled or blotched with black, brown or ash-grey on a blue-tinted or creamy white ground, are usual types of the very variable eggs. They are variable in size and shape as well as markings. Eggs are incubated by the female. The House Sparrow has the shortest incubation period of all the birds: 10-12 days, and a female can lay 25 eggs a summer in New England.

The reproductive success increases with age and this is mainly by changes in timing, with older birds breeding earlier in the season.
