Proardea
''Proardea'' is an extinct genus of heron, containing two species, ''Proardea amissa'' ("lost proto-heron") and ''Proardea? deschutteri'' from the Borgloon Formation of Belgium. It stood about 70 cm (2 ft 4 in) tall and was very similar to a modern heron in shape. The species is known from rather fragmentary fossils in the area of Quercy, France; dated remains are from Pech Desse, a Late Oligocene locality, but the original fossil, a single right tarsometatarsus (MNHN QU-15720), isn't precisely dated and may have come from deposits as early as Late Eocene in age. ''Proardea'' was apparently closely related to the true herons and egrets (Ardeinae). As these genera are only known from the Miocene onwards, ''Proardea'' possibly was a direct ancestor of today's herons and/or egrets. However, the Miocene genus ''Proardeola'' is closely related, or perhaps even synonymous, with ''Proardea''; the former's single species ''Proardeola walkeri'' may thus be ''Proardea walkeri ...

Herons
The herons are long-legged, long-necked, freshwater and coastal birds in the family Ardeidae, with 72 recognised species, some of which are referred to as egrets or bitterns rather than herons. Members of the genera ''Botaurus'' and ''Ixobrychus'' are referred to as bitterns, and, together with the zigzag heron, or zigzag bittern, in the monotypic genus ''Zebrilus'', form a monophyletic group within the Ardeidae. Egrets do not form a biologically distinct group from herons, and tend to be named differently because they are mainly white or have decorative plumes in breeding plumage. Herons, by evolutionary adaptation, have long beaks. The classification of the individual heron/egret species is fraught with difficulty, and no clear consensus exists about the correct placement of many species into either of the two major genera, '' Ardea'' and '' Egretta''. Similarly, the relationships of the genera in the family are not completely resolved. However, one species formerly considered ...

Geronticus Perplexus
__NOTOC__ The small bird genus ''Geronticus'' belongs to the ibis subfamily (Threskiornithinae). Its name is derived from the Greek ''gérontos'' (γέρωντος, "old man") in reference to the bald head of these dark-plumaged birds; in English they are called bald ibises. The genus was erected by the German naturalist Johann Georg Wagler in 1832. The type species was subsequently designated as the southern bald ibis (''Geronticus calvus''). Species Like most ibises, they are gregarious long-legged wading birds with long down-curved bills; they form one subfamily of the Threskiornithidae, the other subfamily being the spoonbills. The two ''Geronticus'' species differ from other ibises in that they have unfeathered faces and heads, breed on cliffs rather than in trees, and prefer arid habitats to the wetlands used by their relatives. Their food contains fewer aquatic animals and more terrestrial ones; they are known to gather together and feed on locust swarms, killing ma ...

Late Eocene
The Eocene ( ) Epoch is a geological epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope 13C in the atmosphere was exceptionally low in comparison with the more common isotope 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Siberia and in what is now Chesapeake Bay. As with other geologic periods, the strata that define the start and end o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MNHN
The French National Museum of Natural History, known in French as the ' (abbreviation MNHN), is the national natural history museum of France and a ' of higher education part of Sorbonne Universities. The main museum, with four galleries, is located in Paris, France, within the Jardin des Plantes on the left bank of the River Seine. It was formally founded in 1793 during the French Revolution, but was begun even earlier in 1635 as the royal garden of medicinal plants. The museum now has 14 sites throughout France.

Oligocene Birds
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] |
Bird Genera
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Bird ...

Phasianidae
The Phasianidae are a family of heavy, ground-living birds, which includes pheasants, partridges, junglefowl, chickens, turkeys, Old World quail, and peafowl. The family includes many of the most popular gamebirds. The family is a large one and includes 185 species divided into 54 genera. It was formerly broken up into two subfamilies, the Phasianinae and the Perdicinae. However, this treatment is now known to be paraphyletic and polyphyletic, respectively, and more recent evidence supports breaking it up into two subfamilies: Rollulinae and Phasianinae, with the latter containing multiple tribes within two clades. The New World quail (Odontophoridae) and guineafowl (Numididae) were formerly sometimes included in this family, but are now typically placed in families of their own; conversely, grouse and turkeys, formerly often treated as distinct families (Tetraonidae and Meleagrididae, respectively), are now known to be deeply nested within Phasianidae, so they are n ...

Ibis
The ibises () (collective plural ibis; classical plurals ibides and ibes) are a group of long-legged wading birds in the family Threskiornithidae, that inhabit wetlands, forests and plains. "Ibis" derives from the Latin and Ancient Greek word for this group of birds. It also occurs in the scientific name of the cattle egret (''Bubulcus ibis'') mistakenly identified in 1757 as being the sacred ibis. Description Ibises all have long, downcurved bills, and usually feed as a group, probing mud for food items, usually crustaceans. They are monogamous and highly territorial while nesting and feeding. Most nest in trees, often with spoonbills or herons. All extant species are capable of flight, but two extinct genera were flightless, namely the kiwi-like ''Apteribis'' in the Hawaiian Islands, and the peculiar '' Xenicibis'' in Jamaica. The word ''ibis'' comes from Latin ''ibis'' from Greek ἶβις ''ibis'' from Egyptian ''hb'', ''hīb''. Beekes, R. S. P. (2009) ''Etymological ...
