Phoenicopterus Minutus
''Phoenicopterus minutus'' is an extinct species of flamingo which inhabited California during the Late Pleistocene. It was originally discovered in San Bernardino County, California in the Lake Manix beds, where it coexisted with a second, larger flamingo species. History The fossils of ''Phoenicopterus minutus'' were discovered in the Lake Manix beds during a large scale project conducted by the United States Geological Survey. Although this project had begun in 1947, much of the bird material from Lake Manix was not collected until the 1950s. The material that formed the basis of the taxon consists of a nearly complete tibiotarsus alongside associated tarsometatarsus elements, which accounts for approximately two thirds of said bone. An additional tarsometatarsus fragment is also known, as are two scapulae and a fragment of the coracoid. The species was named by Hildegard Howard in 1955. Description ''Phoenicopterus minutus'' was said to be the smallest species of flamingo a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Glenoid Facet
The glenoid fossa of the scapula or the glenoid cavity is a bone part of the shoulder. The word ''glenoid'' is pronounced or (both are common) and is from el, gléne, "socket", reflecting the shoulder joint's ball-and-socket form. It is a shallow, pyriform articular surface, which is located on the lateral angle of the scapula. It is directed laterally and forward and articulates with the head of the humerus; it is broader below than above and its vertical diameter is the longest. This cavity forms the glenohumeral joint along with the humerus. This type of joint is classified as a synovial, ball and socket joint. The humerus is held in place within the glenoid cavity by means of the long head of the biceps tendon. This tendon originates on the superior margin of the glenoid cavity and loops over the shoulder, bracing humerus against the cavity. The rotator cuff also reinforces this joint more specifically with the supraspinatus tendon to hold the head of the humerus in ...

Phoenicopteridae
Flamingos or flamingoes are a type of wading bird in the family Phoenicopteridae, which is the only extant family in the order Phoenicopteriformes. There are four flamingo species distributed throughout the Americas (including the Caribbean), and two species native to Afro-Eurasia. A group of flamingoes is called a "flamboyance." Etymology The name ''flamingo'' comes from Portuguese or Spanish ("flame-colored"), which in turn comes from Provençal – a combination of ("flame") and a Germanic-like suffix ''-ing''. The word may also have been influenced by the Spanish ethnonym ("Fleming" or "Flemish"). The name of the genus, ''Phoenicopterus'', is from the Greek , ); other genera names include '' Phoeniconaias,'' which means "crimson/red water nymph (or naiad)", and '' Phoenicoparrus,'' which means "crimson/red bird (though, an unknown bird of omen)". Taxonomy and systematics The family Phoenicopteridae was introduced by the French zoologist Charles Lucien Bonapa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ducks
Duck is the common name for numerous species of waterfowl in the family Anatidae. Ducks are generally smaller and shorter-necked than swans and geese, which are members of the same family. Divided among several subfamilies, they are a form taxon; they do not represent a monophyletic group (the group of all descendants of a single common ancestral species), since swans and geese are not considered ducks. Ducks are mostly aquatic birds, and may be found in both fresh water and sea water. Ducks are sometimes confused with several types of unrelated water birds with similar forms, such as loons or divers, grebes, gallinules and coots. Etymology The word ''duck'' comes from Old English 'diver', a derivative of the verb 'to duck, bend down low as if to get under something, or dive', because of the way many species in the dabbling duck group feed by upending; compare with Dutch and German 'to dive'. This word replaced Old English / 'duck', possibly to avoid confusion w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geese
A goose ( : geese) is a bird of any of several waterfowl species in the family Anatidae. This group comprises the genera '' Anser'' (the grey geese and white geese) and ''Branta'' (the black geese). Some other birds, mostly related to the shelducks, have "goose" as part of their names. More distantly related members of the family Anatidae are swans, most of which are larger than true geese, and ducks, which are smaller. The term "goose" may refer to either a male or female bird, but when paired with "gander", refers specifically to a female one (the latter referring to a male). Young birds before fledging are called goslings. The collective noun for a group of geese on the ground is a gaggle; when in flight, they are called a skein, a team, or a wedge; when flying close together, they are called a plump. Etymology The word "goose" is a direct descendant of,''*ghans-''. In Germanic languages, the root gave Old English ''gōs'' with the plural ''gēs'' and ''gandres'' (beco ...

Cormorants
Phalacrocoracidae is a family of approximately 40 species of aquatic birds commonly known as cormorants and shags. Several different classifications of the family have been proposed, but in 2021 the IOC adopted a consensus taxonomy of seven genera. The great cormorant (''Phalacrocorax carbo'') and the common shag (''Gulosus aristotelis'') are the only two species of the family commonly encountered in Britain and Ireland and "cormorant" and "shag" appellations have been later assigned to different species in the family somewhat haphazardly. Cormorants and shags are medium-to-large birds, with body weight in the range of and wing span of . The majority of species have dark feathers. The bill is long, thin and hooked. Their feet have webbing between all four toes. All species are fish-eaters, catching the prey by diving from the surface. They are excellent divers, and under water they propel themselves with their feet with help from their wings; some cormorant species have been fo ...

Grebes
Grebes () are aquatic diving birds in the order Podicipediformes . Grebes are widely distributed freshwater birds, with some species also found in marine habitats during migration and winter. Some flightless species exist as well, most notably in stable lakes. The order contains a single family, the Podicipedidae, which includes 22 species in six extant genera. Although, superficially, they resemble other diving birds such as loons and coots, they are most closely related to flamingos, as supported by morphological, molecular and paleontological data. Many species are monogamous and are known for their courtship displays, with the pair performing synchronized dances across the water's surface. The birds build floating vegetative nests where they lay several eggs. About a third of the world's grebes are listed at various levels of conservation concerns—the biggest threats including habitat loss, the introduction of invasive predatory fish and human poaching. As such, three sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pelicans
Pelicans (genus ''Pelecanus'') are a genus of large water birds that make up the family Pelecanidae. They are characterized by a long beak and a large throat pouch used for catching prey and draining water from the scooped-up contents before swallowing. They have predominantly pale plumage, except for the brown and Peruvian pelicans. The bills, pouches, and bare facial skin of all pelicans become brightly coloured before the breeding season. The eight living pelican species have a patchy global distribution, ranging latitudinally from the tropics to the temperate zone, though they are absent from interior South America and from polar regions and the open ocean. Long thought to be related to frigatebirds, cormorants, tropicbirds, and gannets and boobies, pelicans instead are now known to be most closely related to the shoebill and hamerkop, and are placed in the order Pelecaniformes. Ibises, spoonbills, herons, and bitterns have been classified in the same order. Fossil evi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fossil Lake (Oregon)
Fossil Lake (designated by the Bureau of Land Management as Fossil Lake Area of Critical Environmental Concern) is a dry lakebed in the remote high desert country of northern Lake County in the U.S. state of Oregon. During the Pleistocene epoch, Fossil Lake and the surrounding basin were covered by an ancient lake. Numerous animals used the lake resources. Over time, the remains of many of these animals became fossilized in the lake sediments. As a result, Fossil Lake has been an important site for fossil collection and scientific study for well over a century. Over the years, paleontologists have found the fossil remains of numerous mammals as well as bird and fish species there. Some of these fossils are 2 million years old. Location Fossil Lake is located in a remote area of northern Lake County, Oregon. It is from the unincorporated community of Christmas Valley by road. Fossil Lake is approximately southeast of Bend and north of Lakeview in straight- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phoenicopterus Copei
''Phoenicopterus copei'' is an extinct species of flamingo that inhabited North America during the Late Pleistocene. Its fossils have been discovered in Oregon, California, Mexico and Florida. Many of these localities preserve the remains of juvenile individuals, indicating that this species nested at the lakes found there. In some areas like California and Florida it coexisted with smaller flamingo species. ''P. copei'' was a large species of ''Phoenicopterus'', described as being greater in size than modern American flamingos. History Although multiple flamingo species are known from North America today, ''Phoenicopterus copei'' was the first fossil taxon of this family described. The species was erected by Robert Wilson Shufeldt in 1891 based on remains discovered at Fossil Lake, Oregon. In 1955 Hildegarde Howard described the remains of two differently sized flamingos from Lake Manix in California, assigning the smaller remains to a new species and the larger to ''Phoenico ...

Leakeyornis
''Leakeyornis'' is an extinct genus of flamingo from the early to middle Miocene of Kenya, primarily in the area of modern day Lake Victoria. Initially described as a species of ''Phoenicopterus'' based on an incomplete skull and various limb bones, it was later found to show a mixture of traits found across modern flamingo genera and subsequently placed in its own genus. It contains a single species, ''Leakeyornis aethiopicus''. History and naming Various fossils of ''Leakeyornis'' were collected by Louis Leakey from Miocene strata of Lake Victoria and later given to the Natural History Museum, London. These remains were first named by Harrison and Walker in 1976 as a species of ''Phoenicopterus'', ''Phoenicopterus aethiopicus''. This description was based on the holotype specimen BMNH A 4382, which represents the back of a beak, while a lower jaw fragment and various appendicular bones were designated as the paratypes. In the years following this publication, additional materi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phoeniconaias Proeses
''Phoeniconaias proeses'' is an extinct species of flamingo from the Pliocene of Australia. Fossil material was described under several names including ''Ocyplanus proeses'' and ''Phoeniconaias gracilis'', which were eventually found to be synonymous. Only material from the Tirari Formation has been dated, while most other material lacks precise information on its age. ''P. proeses'' was one of the smallest species of flamingo, smaller than the modern lesser flamingo which it may be related to. History ''Phoeniconaias proeses'' was first described by Charles Walter De Vis in 1905 alongside a variety of other fossil birds. At the time De Vis was under the impression that the material, a left distal tarsometatarsus only described to have been found in the Lake Eyre basin without precise locality or age, belonged to a type of shorebird. Rich and colleagues argue that this identification may have been a result of De Vis' limited reference collection, which did not include bones of f ...
