Jacanidae Wing Bones
The jacanas (sometimes referred to as Jesus birds or lily trotters) are a group of tropical waders in the family (biology), 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 Polyandry, 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' binomial nomenclature, scientific Latin spelling of the Portuguese language, Portuguese ''jaçanã'' which in turn is derived from a Old Tupi language, Tupi name of the bird, ''ñaha'nã''.

Oligocene
The Oligocene ( ) is a geologic epoch of the Paleogene Period and extends from about 33.9 million to 23 million years before the present ( to ). As with other older geologic periods, the rock beds that define the epoch are well identified but the exact dates of the start and end of the epoch are slightly uncertain. The name Oligocene was coined in 1854 by the German paleontologist Heinrich Ernst Beyrich from his studies of marine beds in Belgium and Germany. The name comes from the Ancient Greek (''olígos'', "few") and (''kainós'', "new"), and refers to the sparsity of extant forms of molluscs. The Oligocene is preceded by the Eocene Epoch and is followed by the Miocene Epoch. The Oligocene is the third and final epoch of the Paleogene Period. The Oligocene is often considered an important time of transition, a link between the archaic world of the tropical Eocene and the more modern ecosystems of the Miocene. Major changes during the Oligocene included a global expansion o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Araçari
An aracari or araçari ( , , ) is any of the medium-sized toucans that, together with the saffron toucanet, make up the genus ''Pteroglossus''. They are brightly plumaged and have enormous, contrastingly patterned bills. These birds are residents in forests and woodlands in the Neotropics. Taxonomy The genus ''Pteroglossus'' was introduced in 1811 by the German zoologist Johann Karl Wilhelm Illiger. The name combines the Ancient Greek ''pteron'' meaning "feather" with ''glōssa'' meaning "tongue". George Robert Gray designated the black-necked aracari as the type species of the genus in 1840. The name "Aracari" was used in 1648 by the German naturalist Georg Marcgrave for the black-necked aracari in his book ''Historia Naturalis Brasiliae''. The name comes from the word ''Arassari'', the name of the bird in the Tupi language. One species, the distinctive saffron toucanet, was formerly placed in the monotypic genus ''Baillonius'', but Renato Kimura and collaborators showed ...

Polyandry
Polyandry (; ) is a form of polygamy in which a woman takes two or more husbands at the same time. Polyandry is contrasted with polygyny, involving one male and two or more females. If a marriage involves a plural number of "husbands and wives" participants of each gender, then it can be called polygamy, group marriage, group or conjoint marriage. In its broadest use, polyandry refers to sexual relations with multiple males within or without marriage. Of the 1,231 societies listed in the 1980 Ethnographic Atlas, 186 were found to be monogamous, 453 had occasional polygyny, 588 had more frequent polygyny, and 4 had polyandry.''Ethnographic Atlas Codebook'' derived from George P. Murdock's ''Ethnographic Atlas'' recording the marital composition of 1,231 societies from 1960 to 1980. Polyandry is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phalarope
__NOTOC__ A phalarope is any of three living species of slender-necked shorebirds in the genus ''Phalaropus'' of the bird family Scolopacidae. Phalaropes are close relatives of the shanks and tattlers, the ''Actitis'' and Terek sandpipers, and also of the turnstones and calidrids. They are especially notable for two things: their unusual nesting behavior, and their unique feeding technique. Two species, the red or grey phalarope (''Phalaropus fulicarius'') and the red-necked phalarope (''P. lobatus'') breed around the Arctic Circle and winter on tropical oceans. Wilson's phalarope (''P. tricolor'') breeds in western North America and migrates to South America. All are in length, with lobed toes and a straight, slender bill. Predominantly grey and white in winter, their plumage develops reddish markings in summer. Taxonomy The genus ''Phalaropus'' was introduced by the French zoologist Mathurin Jacques Brisson in 1760 with the red phalarope (''Phalaropus fulicarius'') as t ...

Wader
245px, A flock of Dunlins and Red knots">Red_knot.html" ;"title="Dunlins and Red knot">Dunlins and Red knots Waders or shorebirds are birds of the order Charadriiformes commonly found wikt:wade#Etymology 1, wading along shorelines and mudflats in order to foraging, forage for food crawling or burrowing in the mud and sand, usually small arthropods such as aquatic insects or crustaceans. 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 ...

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] |
Coraciidae
Coraciidae is a family of Old World birds, which is known as rollers because of the aerial acrobatics some of these birds perform during courtship or territorial flights. Rollers resemble crows in size and build, and share the colourful appearance of kingfishers and bee-eaters, blues and pinkish or cinnamon browns predominating. The two inner front toes are connected, but not the outer one. They are mainly insect eaters, with ''Eurystomus'' species taking their prey on the wing, and those of the genus ''Coracias'' diving from a perch to catch food items from on the ground, like giant shrikes. Although living rollers are birds of warm climates in the Old World, fossil records show that rollers were present in North America during the Eocene. They are monogamous and nest in an unlined hole in a tree or in masonry, and lay 2–4 eggs in the tropics, 3–6 at higher latitudes. The eggs, which are white, hatch after 17–20 days, and the young remain in the nest for approximately ano ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Thinocoridae
The seedsnipes are a small family, Thinocoridae, of small gregarious waders which have adapted to a herbivorous diet. The family is divided into two genera, ''Attagis'' and ''Thinocorus'', each containing two species. The family has a South American distribution, in the Andean and Patagonian regions. The relationships with other families within the order Charadriiformes are uncertain; it has been suggested that the plains wanderer of Australia, the jacanas and the painted snipes are their closest relatives. The plains wanderer in particular has a similar feeding ecology, although differs markedly in breeding biology. The family's common name is misleading, as they do not resemble true snipe, having short bills on small heads, and seeds do not form a major part of the diet.Fjeldså, J.
