Jacanidae
The jacanas (sometimes referred to as Jesus birds or lily trotters) are a group of tropical waders in the family Jacanidae. They are found in the tropical regions around the world. They are noted for their elongated toes and toenails that allow them to spread out their weight while foraging on floating or semi-emergent aquatic vegetation. They are also among the rare groups of birds in which females are larger, and several species maintain harems of males in the breeding season with males solely responsible for incubating eggs and taking care of the chicks. Etymology and pronunciation The pronunciation of the word jacana is debated. ''Jacana'' is Linnæus' scientific Latin spelling of the Portuguese ''jaçanã'' which in turn is derived from a Tupi name of the bird, ''ñaha'nã''. The Portuguese word is pronounced approximately . As in façade, Provençal, and araçari, the Ç is meant to be pronounced as an S. US dictionaries give various pronunciations: , , as well as th ...

Hydrophasianus Chirurgus
The pheasant-tailed jacana (''Hydrophasianus chirurgus'') is a jacana in the monotypic genus ''Hydrophasianus''. Like all other jacanas, they have elongated toes and nails that enable them to walk on floating vegetation in shallow lakes, their preferred habitat. They may also swim or wade in water reaching their body while foraging mainly for invertebrate prey. They are found in tropical Asia from Yemen in the west to the Philippines in the east and move seasonally in parts of their range. They are the only jacanas that migrate long distances and have different non-breeding and breeding plumages. The pheasant-tailed jacana forages by swimming or by walking on aquatic vegetation. Females are larger than males and are polyandrous, laying several clutches that are raised by different males in their harem. Description The pheasant-tailed jacana is conspicuous and unmistakable. It is the longest species in the jacana family when the tail streamers are included. The breeding plumage i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Comb-crested Jacana
The comb-crested jacana (''Irediparra gallinacea''), also known as the lotusbird or lilytrotter, is the only species of jacana in the genus ''Irediparra''. Like other jacana species, it is adapted to the floating vegetation of tropical freshwater wetlands. Description This species is unmistakable. It has a black crown and hindneck with a fleshy red wattle covering the forehead and forecrown, contrasting with a white face and throat. The comb is pinker in breeding adults, more orange when not breeding. There is a broad black band on the lower breast with white belly. The underwing and flight feathers, which show most prominently in flight, are black. Back and upperwing mainly grey-brown with black primary coverts, rump and tail. The long legs with extremely long toes trail in flight. The male is slightly smaller than the female and measures in length and weighs .

Jacana (genus)
''Jacana'' is the genus comprising the two jacanas of the Americas: the northern jacana, ''Jacana spinosa'', and the wattled jacana, ''Jacana jacana''. The two species are very similar to each other: about long, with long necks and fairly long yellow bills. Adults are black and chestnut-brown, with pale yellow-green flight feathers that contrast conspicuously when a bird flies. Their legs are long and grayish, and as in all jacanas, their toes are extremely long for walking on aquatic vegetation such as lily pads. They have frontal shields (like those of coots) and wattles; differences in these are the most noticeable differences between the species. Juveniles are brown above and white below, with a buff-white stripe above the eye and a dark stripe behind it. The dark colors are somewhat darker on the juvenile wattled jacana than on the northern. Together the species occur in marshes in the American tropics and subtropics. The northern jacana's range meets that of the wattled ...

Wader

The term "wader" is used in Europe, while "shorebird" is used in North America, where "wader" may be used instead to refer to long-legged wading birds such as storks and herons. There are about 210 species of wader, most of which live in wetland or coastal environments. Many species of Arctic and temperate regions are strongly migratory, but tropical birds are often resident, or move only in response to rainfall patterns. Some of the Arctic species, such as the little stint, are amongst the longest distance migrants, spending the non- breeding season in the southern hemisphere. Many of the s ...

Actophilornis
''Actophilornis'' is a genus of jacana. It contains two species restricted to Africa and its surrounding islands. Taxonomy The genus ''Actophilornis'' was introduced in 1925 by the American ornithologist Harry C. Oberholser with the African jacana as the type species. ''Actophilornis'' was a replacement name for ''Actophilus'' which was pre-occupied. The name combines the Ancient Greek ''aktē'' meaning "river bank" or "coastal strand", ''-philos'' meaning "-loving" and ''ornis'' meaning "bird". The genus contains two species: * African jacana, ''Actophilornis africanus'' * Madagascar jacana The Madagascar jacana (''Actophilornis albinucha'') is a species of bird in the family Jacanidae.

Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia.
