Ornithology is a branch of zoology that concerns the study of birds. Several aspects of ornithology differ from related disciplines, due partly to the high visibility and the aesthetic appeal of birds. It has also been an area with a large contribution made by amateurs in terms of time, resources, and financial support. Studies on birds have helped develop key concepts in biology including evolution, behaviour and ecology such as the definition of species, the process of speciation, instinct, learning, ecological niches, guilds, island biogeography, phylogeography, and conservation.
Anseriformes is an order of birds also known as waterfowl that comprises about 180 living species of birds in three families: Anhimidae, Anseranatidae, and Anatidae, the largest family, which includes over 170 species of waterfowl, among them the ducks, geese, and swans. Most modern species in the order are highly adapted for an aquatic existence at the water surface. With the exception of screamers, males have penises, a trait that has been lost in the Neoaves. Due to their aquatic nature, most species are web-footed.
The mesites (Mesitornithidae) are a family of birds that are part of a clade (Columbimorphae) that include Columbiformes and Pterocliformes. They are smallish flightless or near flightless birds endemic to Madagascar. They are the only family with more than two species in which every species is threatened.
The Pelagornithidae, commonly called pelagornithids, pseudodontorns, bony-toothed birds, false-toothed birds or pseudotooth birds, are a prehistoric family of large seabirds. Their fossil remains have been found all over the world in rocks dating between the Early Paleocene and the Pliocene-Pleistocene boundary.
John Alan Feduccia is a paleornithologist specializing in the origins and phylogeny of birds. He is S. K. Heninger Distinguished Professor Emeritus at the University of North Carolina. Feduccia's authored works include three major books, The Age of Birds, The Origin and Evolution of Birds, and Riddle of the Feathered Dragons.
Storrs Lovejoy Olson was an American biologist and ornithologist who spent his career at the Smithsonian Institution, retiring in 2008. One of the world's foremost avian paleontologists, he was best known for his studies of fossil and subfossil birds on islands such as Ascension, St. Helena and Hawaii. His early higher education took place at Florida State University in 1966, where he obtained a B.A. in biology, and the University of Florida, where he received an M.S. in biology. Olson's doctoral studies took place at Johns Hopkins University, in what was then the School of Hygiene and Public Health. He was married to fellow paleornithologist Helen F. James.
Cranial kinesis is the term for significant movement of skull bones relative to each other in addition to movement at the joint between the upper and lower jaws. It is usually taken to mean relative movement between the upper jaw and the braincase.
Bradley Curtis Livezey was an American ornithologist with scores of publications. His main research included the evolution of flightless birds, the systematics of birds, and the ecology and behaviour of steamer ducks.
The Archaeornithes, classically Archæornithes, is an extinct group of the first primitive, reptile-like birds. It is an evolutionary grade of transitional fossils, the primitive birds halfway between non avian dinosaur ancestors and the derived modern birds.
Richard Charles Banks was an American author, ornithologist and Emeritus Research Zoologist on staff with the Patuxent Wildlife Research Center run by the U.S. Geological Survey and stationed at the Smithsonian Institution in Washington, D.C. He is the founder of the Ornithological Council and known for his study of the migratory systems, patterns, and geographic variations of North American birds, primarily focusing on the research and analysis of Greater White-fronted Geese.
Robert Wilson ShufeldtJr. was an American osteologist, myologist, museologist and ethnographer who contributed to comparative studies of bird anatomy and forensic science. He held strong views on race and was a proponent of white supremacy. A scandal and subsequent divorce from his second wife, the granddaughter of the famous ornithologist John James Audubon, led to a landmark judgment by the Supreme Court of the United States of America on the subject of alimony and bankruptcy.
Gruimorphae is a clade of birds that contains the orders Charadriiformes and Gruiformes identified by molecular analysis. This grouping has had historical support, as various charadriiform families such as the families Pedionomidae and Turnicidae were classified as gruiforms. It may also have support from the fossil record since the discovery of Nahmavis from the Early Eocene of North America.
Picocoraciae is a clade that contains the order Bucerotiformes and the clade Picodynastornithes supported by various genetic analysis and morphological studies. While these studies supported a sister grouping of Coraciiformes and Piciformes, a large scale, sparse supermatrix has suggested alternative sister relationship between Bucerotiformes and Piciformes instead.
Columbimorphae is a clade discovered by genome analysis that includes birds of the orders Columbiformes, Pterocliformes (sandgrouse), and Mesitornithiformes (mesites). Previous analyses had also recovered this grouping, although the exact relationships differed. Some studies indicated a sister relationship between sandgrouse and pigeons while other studies favored a sister grouping of mesites and sandgrouse instead.
Picodynastornithes is a clade that contains the orders Coraciiformes and Piciformes. This grouping also has current and historical support from molecular and morphological studies.
Nagahisa Kuroda was a Japanese ornithologist. He wrote several books on the birds of Japan and worked on Japanese encephalitis, the systematics of shearwaters, ducks and on avian anatomy.
Philip Strong Humphrey was an ornithologist, museum curator, and professor of zoology.
Paul Slud was an American ornithologist and tropical ecologist, known for his 1960 monograph The Birds of Finca "La Selva," Costa Rica and his 1964 book The Birds of Costa Rica: Distribution and Ecology.
Pelecanimorphae is a clade of aequornithean birds that comprises the orders Ciconiiformes, Suliformes and Pelecaniformes. In the past the name has been used as a homonym for Pelecaniformes.
Litusilvanae is a proposed clade of birds, position as the sister clade to Aequorlitornithes. This clade comprises Gruimorphae and Strisores. While different lines of evidence from molecular, morphology and the fossil record has found support in the clades Gruimorphae and Strisores Wu et al. (2024) was the first to find support in such a novel sister group relationship between these two taxa.
