Gelochelidon
''Gelochelidon'' is a genus of terns. It was considered a monotypic genus until the Australian tern was split from the gull-billed tern. Taxonomy The genus ''Gelochelidon'' was introduced in 1830 by the German zoologist Alfred Brehm. The type species is the gull-billed tern. The name combines the Ancient Greek Ancient Greek (, ; ) includes the forms of the Greek language used in ancient Greece and the classical antiquity, ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Greek ... ''gelaō'' meaning "to laugh" with ''khelidōn'' meaning "swallow".

Gull-billed Tern
The gull-billed tern (''Gelochelidon nilotica''), formerly ''Sterna nilotica'', is a tern in the family Laridae. It is widely distributed and breeds in scattered localities in Europe, Asia, northwest Africa, and the Americas. The Australian gull-billed tern was previously considered a subspecies. Taxonomy The gull-billed tern was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with terns in the genus '' Sterna'' and coined the binomial name ''Sterna nilotica''. Gmelin based his description on the "Egyptian tern" that had been described in 1785 by the English ornithologist John Latham in his book ''A General Synopsis of Birds''. Latham had in turn based his own account on that by the Swedish naturalist Fredrik Hasselquist that was published in 1757. The gull-billed tern was moved to the resurrected genus '' Gelochelidon'' based on a molecular phylogenetic study ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Australian Tern
The Australian tern or Australian gull-billed tern (''Gelochelidon macrotarsa'') is a tern in the family Laridae, native to Australia. The genus name is from Ancient Greek ''gelao'', "to laugh", and ''khelidon'', "swallow". Taxonomy John Gould described ''Sterna macrotarsa'' from a specimen held at King's College, London in 1837. Although first described as a species, throughout most of the 20th and early 21st centuries it was generally considered to be a subspecies of the gull-billed tern, but was re-elevated to species status by the IOC World Bird List in 2019 in its Version 9.2. Description This is a fairly large and powerful tern, similar in size and general appearance to a Sandwich tern, but the short thick gull-like bill, broad wings, long legs and robust body are distinctive. The summer adult has pale grey upperparts, white underparts, a black cap, strong black bill and black legs. The call is a characteristic ''ker-wik''. It is in length and in wingspan. Its weight ran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tern
Terns are seabirds in the family Laridae, subfamily Sterninae, that have a worldwide distribution and are normally found near the sea, rivers, or wetlands. Terns are treated in eleven genera in a subgroup of the family Laridae, which also includes several genera of gulls and the skimmers (''Rynchops''). They are slender, lightly built birds with long, forked tails, narrow wings, long bills, and relatively short legs. Most species are pale grey above and white below with a contrasting black cap to the head, but the marsh terns, the black-bellied tern, the Inca tern, and some noddies have dark body plumage for at least part of the year. The sexes are identical in appearance, but young birds are readily distinguishable from adults. Terns have a non-breeding plumage, which usually involves a white forehead and much-reduced black cap. Terns are long-lived birds and are relatively free from natural predators and parasites; most species are declining in numbers due directly o ...

Laridae
Laridae is a family of seabirds in the order Charadriiformes that includes the gulls, terns (including white terns), noddies, and skimmers. It includes around 100 species arranged into 22 genera. They are an adaptable group of mostly aerial birds found worldwide. Taxonomy The family Laridae was introduced (as Laridia) by the French polymath Constantine Samuel Rafinesque in 1815. Historically, Laridae were restricted to the gulls, while the terns were placed in a separate family, Sternidae, and the skimmers in a third family, Rynchopidae. The noddies were traditionally included in Sternidae. In 1990 Charles Sibley and Jon Ahlquist included auks and skuas in a broader family Laridae. A molecular phylogenetic study by Baker and colleagues published in 2007 found that the noddies in the genus '' Anous'' formed a sister group to a clade containing the gulls, skimmers, and the other terns. To create a monophyletic family group, Laridae was expanded to include the genera that had ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alfred Brehm
Alfred Edmund Brehm (; 2 February 1829 – 11 November 1884) was a German zoologist and writer. His multi-volume book '' Brehms Tierleben'', which he co-authored with Eduard Pechuël-Loesche, Wilhelm Haacke, and Richard Schmidtlein, became a household word for popular zoological literature. He was the first director of the Zoological Garden of Hamburg. Early life Brehm grew up in the small Thuringian village of Unter renthendorf as the son of the pastor Christian Ludwig Brehm, and of his second wife Bertha née Reiz. Christian Ludwig Brehm made a name for himself as an ornithologist by publications and through an extensive collection of stuffed birds. The collection, held in the parsonage and consisting of over 9,000 dead birds, offered a glimpse into the world of European birds. As a boy he helped expand his father by collecting specimens and became an excellent marskman. His father's research gave the younger Brehm an interest in zoology, but at first he wanted to be ...

Type Species
In International_Code_of_Zoological_Nomenclature, zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological Type (biology), type wiktionary:en:specimen, specimen (or specimens). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the International Code of Nomenclature for algae, fungi, and plants, code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name with that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have suc ...

Christian Ludwig Brehm
Christian Ludwig Brehm (24 January 1787 – 23 June 1864) was a German pastor and Ornithology, ornithologist. He was the father of the Zoology, zoologist Alfred Brehm. Life Brehm was born in Schönau (Odenwald), Schönau near Gotha on 24 January 1787. He was educated at University of Jena to be ordained as minister at Renthendorf in 1813 where he remained until his death on 23 June 1864. He wrote ''Beiträge zur Vogelkunde'' (1820–22), which described 104 species of German birds in minute detail, and ''Handbuch der Naturgeschichte aller Vögel Deutschlands'' (1831) which described 900 bird species. Brehm accumulated a collection of 15,000 birds until his death, which included samples from his son, Alfred Brehm. Alfred collected these birds from Sudan, Egypt, and throughout Europe. He offered these to the Natural History Museum, Berlin, Berlin Zoological Museum in March 1835 because he feared that a storm would destroy his house, but the sale fell through. After his death, ...

Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical syste ...
