Ornithology (from Greek: ὄρνις, ὄρνιθος, ornis, ornithos, "bird"; and λόγος, logos, "knowledge") is the branch of zoology concerned with the study of birds. Several aspects of the study of ornithology differ from closely related disciplines, due partly to the high visibility and the aesthetic appeal of birds. Most marked among these is the extent of field studies undertaken by amateur volunteers working within the parameters of strict scientific methodology.

The science of ornithology has a long history and studies on birds aided the introduction and refinement of key concepts in evolution, behaviour and ecology such as those of species, speciation, instinct, learning, ecological niches, guilds, island biogeography, phylogeography and conservation. While early ornithology was principally concerned with descriptions and distributions of species, ornithologists today concern themselves with answering specific questions, often using birds as models to test hypotheses and predictions based on theory. A wide range of tools and techniques are used in ornithology and innovations are constantly made.

The history of ornithology reflects trends in the history of biology. Historic trends include the move from descriptions to the identification of patterns and an understanding of the processes producing the patterns.

Humans must have observed birds from the earliest times, and stone age drawings are among the oldest indications of interest in birds. Birds were perhaps important as a food source, and bones of as many as 80 species have been found in excavations of early Stone Age settlements.

Cultures around the world have rich vocabularies related to birds. Traditional bird names are often based on detailed knowledge of the behavior, with many names being onomatopoeic, many still in use. Traditional knowledge continues to be of importance especially due to their relevance in conservation. Most of this information is passed on through oral traditions (see ethno-ornithology). Hunting of birds would also have required considerable knowledge of their habits. Poultry farming and falconry were practised from early times in many parts of the world. Artificial incubation of poultry was practised in China (246 BC) and Egypt (at least 400 BC). The Egyptians also showed a great deal of knowledge of birds through their use of bird symbols in hieroglyphs, many of which, though stylized, are still recognizable.

Aristotle in 350 BC in his Historia Animalium noted the habit of bird migration, moulting, egg laying and life spans. He also introduced several incorrect concepts such as the idea that swallows hibernated in winter. He however noted that cranes travelled from the steppes of Scythia to the marshes at the headwaters of the Nile. The idea of swallow hibernation became so well established that, even as late as in 1878, Elliott Coues listed as many as 182 contemporary publications dealings with the hibernation of swallows and no evidence to contradict the theory. Similar misconceptions existed regarding the breeding of Barnacle geese. Their nests had not been seen and it was believed that they grew by transformations of goose barnacles, an idea that became prevalent from around the 11th century and noted by Bishop Giraldus Cambrensis (Gerald of Wales) in Topographia Hiberniae (1187).

The origins of falconry have been traced to Mesopotamia and the earliest record comes from the reign of Sargon II (722–705 BC). Falconry made its entry to Europe only after AD 400, brought in from the East after invasions by the Huns and Allans. Frederick II of Hohenstaufen (1194 – 1250) learnt about Arabian falconry during wars in the region and obtained an Arabic treatise on falconry by Moamyn. He had this work translated into Latin and also conducted experiments on birds in his menagerie. By sealing the eyes of vultures and placing food nearby, he concluded that they found food by sight, and not by smell. He also developed methods to keep and train falcons. The studies that he undertook over nearly 30 years, were published in 1240 as De Arte Venandi cum Avibus (The Art of Hunting with Birds), considered one of the earliest studies on bird behaviour.

Several early German and French scholars compiled old works and conducted new research on birds. These included Guillaume Rondelet who described his observations in the Mediterranean and Pierre Belon who described the fish and birds that he had seen in France and the Levant. Belon's Book of Birds (1555) is a folio volume with descriptions of some two hundred species. His comparison of the skeleton of humans and birds is considered as a landmark in comparative anatomy. Volcher Coiter (1534-1576), a Dutch anatomist made detailed studies of the internal structures of birds and produced a classification of birds, De Diferentiis Avium (around 1572), that was based on structure and habits. Konrad Gesner wrote the Vogelbuch and Icones avium omnium around 1557. Like Gesner, Ulisse Aldrovandi, an encyclopedic naturalist began a 14-volume natural history with three volumes on birds, entitled ornithologiae hoc est de avibus historiae libri XII which was published from 1599 to 1603. Aldrovandi showed great interest in plants and animals and his work included 3000 drawings of fruits, flowers, plants and animals, published in 363 volumes. His Ornithology alone covers 2000 pages and included such aspects as the chicken and poultry techniques.William Turner's Historia Avium ("History of Birds"), published at Cologne in 1544, was another early ornithological work. He notes that the kite in cities of England would snatch the meat out of the hands of children. In his day the Osprey was well known but disliked for it was believed to empty their fishponds; anglers used to mix their bait with its fat. Turner's work was written in a tone that reflected violent times; quite unlike Gilbert White's The Natural History and Antiquities of Selborne which was written in a more tranquil era. In the 17th century Francis Willughby (1635-1672) and John Ray (1627-1705) came up with the first major system of bird classification that was based on function and morphology rather than on form or behaviour. Willughby's Ornithologiae libri tres (1676) completed by John Ray is sometimes considered to mark the beginning of scientific ornithology. Ray also worked on Ornithologia which was published posthumously in 1713 as Synopsis methodica avium et piscium. The earliest list of British birds, Pinax Rerum Naturalium Britannicarum was written by Christopher Merrett in 1667, however it was not considered of value by many including John Ray.

Towards the late 1700s, Mathurin Jacques Brisson (1723-1806) and Comte de Buffon (1707-1788) began new works on birds. Brisson produced a six-volume work Ornithologie in 1760 and Buffon's included nine volumes (volumes 16-24) on birds Histoire naturelle des oiseaux (1770-1785) in his work on science Histoire naturelle générale et particulière (1749-1804). Coenraad Jacob Temminck (1778 - 1858) sponsored François Le Vaillant to collect bird specimens in Africa and this resulted in Le Vaillant's six-volume Histoire naturelle des oiseaux d'Afrique (1796-1808). Louis Jean Pierre Vieillot (1748-1831) spent ten years studying North American birds and wrote the Histoire naturelle des oiseaux de l'Amerique septentrionale (1807-1808?). Vieillot pioneered in the use of life-histories and habits in classification.

It was not until the Victorian era—with the emergence of the gun, the concept of natural history, and the collection of natural objects such as bird eggs and skins—that ornithology emerged as a specialized science. This specialization led to the formation in Britain of the British Ornithologists' Union in 1858. In 1859 the members founded its journal The Ibis. The sudden spurt in ornithology was also due in part to colonization. A hundred years later, in 1959, R. E. Moreau noted that ornithology in this period was preoccupied with the geographical distributions of various species of birds.

No doubt the preoccupation with widely extended geographical ornithology, was fostered by the immensity of the areas over which British rule or influence stretched during the 19th century and for some time afterwards.

The bird collectors of the Victorian era observed the variations in bird forms and habits across geographic regions, noting local specialization and variation in widespread species. The collections of museums and private collectors grew with contributions from various parts of the world. The naming of species with binomials and the organization of birds into groups based on their similarities became the main work of museum specialists. The variations in widespread birds across geographical region caused the introduction of trinomial names.

The search for patterns in the variations of birds was attempted by many. Early ornithologists like William Swainson followed the Quinarian system and this was replaced by more complex "maps" of affinities in works by Hugh Edwin Strickland and Alfred Russell Wallace.

The Galapagos finches were especially influential in the development of Charles Darwin's theory of evolution. His contemporary Alfred Russel Wallace also noted these variations and the geographical separations between different forms leading to the study of biogeography. Wallace was influenced by the work of Philip Lutley Sclater on the distribution patterns of birds.

For Darwin, the problem was how species arose from a common ancestor, but he did not attempt to find rules for delineation of species. The species problem, was tackled by the ornithologist Ernst Mayr. Mayr was able to demonstrate that geographical isolation and the accumulation of genetic differences led to the splitting of species.

There are two essentially different kinds of ornithology: systematic or scientific, and popular. The former deals with the structure and classification of birds, their synonymies and technical descriptions. The latter treats of their habits, songs, nesting, and other facts pertaining to their life histories.

Sometimes it seems that elaborate plans and statistics are made to prove what is commonplace knowledge to the mere collector, such as that hunting parties often travel more or less in circles.

David Lack's studies on population ecology sought to find the processes involved in the regulation of population based on the evolution of optimal clutch sizes. He concluded that population was regulated primarily by density-dependent controls, and also suggested that natural selection produces life-history traits that maximize the fitness of individuals. Others like Wynne-Edwards interpreted population regulation as a mechanism that aided the "species" rather than individuals. This led to widespread and sometimes bitter debate on what constituted the "unit of selection". Lack also pioneered the use of many new tools for ornithological research, including the idea of using radar to study bird migration.

Birds were also widely used in studies of the niche hypothesis and Georgii Gause's competitive exclusion principle. Work on resource partitioning and the structuring of bird communities through competition were made by Robert MacArthur. Patterns of biodiversity also became a topic of interest. Work on the relationship of the number of species to area and its application in the study of island biogeography was pioneered by E. O. Wilson and Robert MacArthur. These studies led to the development of the discipline of landscape ecology.

John Hurrell Crook studied the behaviour of weaverbirds and demonstrated the links between ecological conditions, behaviour and social systems. Principles from economics were introduced to the study of biology by J. L. Brown. This led to the study of behaviour using cost-benefit analyses. The rising interest in sociobiology also led to a spurt of bird studies in this area.

The study of imprinting behaviour in ducks and geese by Konrad Lorenz and the studies of instinct in Herring Gulls by Nicolaas Tinbergen, led to the establishment of the field of ethology. The study of learning became an area of interest and the study of bird song has been a model for studies in neuro-ethology. The role of hormones and physiology in the control of behaviour has also been aided by bird models. These have helped in the study of circadian and seasonal cycles. Studies on migration have attempted to answer questions on the evolution of migration, orientation and navigation.

The growth of genetics and the rise of molecular biology led to the application of the gene-centered view of evolution to explain avian phenomena. Studies on kinship and altruism, such as helpers, became of particular interest. The idea of inclusive fitness was used to interpret observations on behaviour and life-history and birds were widely used models for testing hypotheses based on theories postulated by W. D. Hamilton and others.

The new tools of molecular-biology changed the study of bird systematics. Systematics changed from being based on phenotype to the underlying genotype. The use of techniques such as DNA-DNA hybridization to study evolutionary relationships was pioneered by Charles Sibley and Jon Edward Ahlquist resulting in what is called the Sibley-Ahlquist taxonomy. These early techniques have been replaced by newer ones based on mitochondrial DNA sequences and molecular phylogenetics approaches that make use of computational procedures for sequence alignment, construction of phylogenetic trees and calibration of molecular clocks to infer evolutionary relationships. Molecular techniques are also widely used in studies of avian population biology and ecology.

The rise of field guides for the identification of birds was another major innovation. The early guides were large and cumbersome and were mainly focussed on identifying specimens in the hand. The earliest of the new generation of field guides was prepared by Florence Merriam, sister of Clinton Hart Merriam, the mammalogist. This was published in 1887 in a series Hints to Audubon Workers:Fifty Birds and How to Know Them in Grinnell's Audubon Magazine. These were followed by new field guides including classics by Roger Tory Peterson.

Organizations were started in many countries and these grew rapdily in membership, most notable among them being the Royal Society for the Protection of Birds (RSPB) in Britain and the Audubon Society in the US. The Audubon Society started in 1885. Both these organization were started with the primary objective of conservation. The RSPB, born in 1889, grew from a small group of women in Croydon who met regularly and called themselves the Fur, Fin and Feather Folk and who took a pledge "to refrain from wearing the feathers of any birds not killed for the purpose of food, the Ostrich only exempted." The organization did not allow men as members initially, avenging a policy of the British Ornithologists' Union to keep out women. Unlike the RSPB, which was primarily conservation oriented, the British Trust for Ornithology (BTO) was started in 1933 with the aim of advancing ornithological research. Members were often involved in collaborative ornithological projects. These projects have resulted in atlases which detail the distribution of bird species across Britain. In the United States, the Breeding Bird Surveys, conducted by the US Geological Survey have also produced atlases with information on breeding densities and changes in the density and distribution over time. Other volunteer collaborative ornithology projects were subsequently established in other parts of the world.

The tools and techniques of ornithology are varied and new inventions and approaches are quickly incorporated. The techniques may be broadly dealt under the categories of those that are applicable to specimens and those that are used in the field, however the classification is imperfect as many of the newer non-destructive sampling and analysis techniques are applicable in both the laboratory and field.

The earliest approaches to modern bird study involved the collection of eggs, a practice known as oology. While collecting became a pastime for many amateurs, the labels associated with these early egg collections made them unreliable for the serious study of bird breeding. In order to preserve eggs, a tiny hole was pierced and the contents extracted. This technique became standard with the invention of the blow drill around 1830. Egg collection is no longer popular; however historic museum collections have been of value in determining the effects of pesticides such as DDT on physiology. Museum bird collections continue to act as a resource for taxonomic studies.

The use of bird skins to document species has been a standard part of systematic ornithology. Bird skins are prepared by retaining the key bones of the wings, leg and skull along with the skin and feathers. In the past, they were treated with arsenic to prevent fungal and insect (mostly dermestid) attack. Arsenic, being toxic, was replaced by borax. Sportsmen became familiar with these skinning techniques and started sending in their skins to museums, some of them from distant locations. This led to the formation of huge collections of bird skins in museums in Europe and North America. Many private collections were also formed. These became references for comparison of species and the ornithologists at these museums were able to compare species from different locations, often places that they themselves never visited. Morphometrics of these skins, particularly the lengths of the tarsus, bill, tail and wing became important in the descriptions of bird species. These skin collections have been utilized in more recent times for studies on molecular phylogenetics by the extraction of ancient DNA. The importance of type specimens in the description of species make skin collections a vital resource for systematic ornithology. However, with the rise of molecular techniques, it has now become possible to establish the taxonomic status of new discoveries, such as the Bulo Burti Boubou Laniarius liberatus and the Bugun Liocichla Liocichla bugunorum, using blood, DNA and feather samples as the holotype material.

Other methods of preservation include the storage of specimens in spirit. Such wet-specimens have special value in physiological and anatomical study, apart from providing better quality of DNA for molecular studies. Freeze drying of specimens has also been attempted in more recent times. While the technique has advantages in that it preserves stomach contents and anatomy, it may have the same problems as dry skins in that shrinkage can occur leading to errors in morphometrics.

The study of birds in the field was helped enormously by improvements in optics. Photography made it possible to document birds in the field with great accuracy. High power spotting scopes today allow observers to detect minute morphological differences that were earlier possible only by examination of the specimen in the hand.

The capture and marking of birds enables detailed studies of life-history. Techniques for capturing birds are varied and include the use of bird liming for perching birds, mist nets for woodland birds, cannon netting for open area flocking birds, the bal-chatri trap for raptors, decoys and funnel traps for water birds.

The bird in the hand may be examined and measurements can be made including standard lengths and weight. Feather moult and skull ossification provide indications of age and health. Sex can be determined by examination of anatomy in some sexually non-dimorphic species. Blood samples may be drawn to determine hormonal conditions in studies of physiology, identify DNA markers for studying genetics and kinship in studies of breeding biology and phylogeography. Blood may also be used to pathogens and arthropod borne viruses. Ectoparasites may be collected for studies of coevolution and zoonoses. In many of cryptic species, measurements (such as the relative lengths of wing feathers in warblers) are vital in establishing identity.

Captured birds are often marked for future recognition. Rings or bands provide long-lasting identification but require capture for the information on them to be read. Field identifiable marks such as coloured bands, wing tags or dyes enable short-term studies where individual identification is required. Mark and recapture techniques make demographic studies possible. Ringing has traditionally been used in the study of migration. In recent times satellite transmitters provide the ability to track migrating birds in near real-time.

Techniques for estimating population density include point counts, transects and territory mapping. Observations are made in the field using carefully designed protocols and the data may be analysed to estimate bird diversity, relative abundance or absolute population densities. These methods may be used repeatedly over large time spans to monitor changes in the environment. Camera traps have been found to be a useful tool for the detection and documentation of elusive species, nest predators and in the quantitative analysis of frugivory, seed dispersal and behaviour.

Many aspects of bird biology are difficult to study in the field. These include the study of behavioural and physiological changes that require a long duration of access to the bird. Non-destructive samples of blood or feathers taken during field studies may be studied in the laboratory. For instance, the variation in the ratios of stable hydrogen isotopes across latitudes makes it possible to roughly establish the origins of migrant birds using mass spectroscopic analysis of feather samples. These techniques can be used in combination with other techniques such as ringing.

The first attenuated vaccine developed by Louis Pasteur was for fowl cholera and was tested on poultry in 1878. Poultry continues to be used as a model for many studies in non-mammalian immunology.

Studies in bird behaviour include the use of tamed and trained birds in captivity. Studies on bird intelligence and song learning have been largely laboratory based. Field researchers may make use of a wide range of techniques such as the use of dummy owls to elicit mobbing behaviour, dummy males or the use of call playback to elicit territorial behaviour and thereby to establish the boundaries of bird territories.

Studies of bird migration including aspects of navigation, orientation and physiology are often studied using captive birds in special cages that record their activities. The Emlen funnel for instance makes use of a cage with an inkpad at the centre and a conical floor where the ink marks can be counted to identify the direction in which the bird attempts to fly. The funnel can have a transparent top and visible cues such as the direction of sunlight may be controlled using mirrors or the positions of the stars simulated in a planetarium.

The entire genome of the domestic fowl Gallus gallus was sequenced in 2004 and work is on to sequence the genome of the Zebra Finch (Taeniopygia guttata). Such whole genome sequencing projects allow for studies on evolutionary processes involved in speciation. Associations between the expression of genes and behaviour may be studied using candidate genes. Variations in the exploratory behaviour of Great Tits (Parus major) have been found to be linked with a gene orthologous to the human gene Drd4 (Dopamine receptor D4) which is known to be associated with novelty-seeking behaviour. The role of gene expression in developmental differences and morphological variations have been studied in Darwin's finches. The difference in the expression of Bmp4 have been shown to be associated with changes in the growth and shape of the beak.

With the widespread interest in birds, it has been possible to use a large number of people to work on collaborative ornithological projects that cover large geographic scales. These citizen science projects include nation-wide projects such as the Christmas Bird Count, Backyard Bird Count, the North American Breeding Bird Survey, the Canadian EPOQ or regional projects such as the Asian Waterfowl Census. These projects help to identify distributions of birds, their population densities and changes over time, arrival and departure dates of migration, breeding seasonality and even population genetics. The results of many of these projects are published as bird atlases. Studies of migration using bird ringing or colour marking often involve the cooperation of people and organizations in different countries.

Wild birds impact many human activities while domesticated birds are important sources of eggs, meat, feathers and other products. Applied and economic ornithology aim to reduce the ill effects of problem birds and enhance gains from beneficial species.

The role of some species of birds as pests has been well known, particularly in agriculture. Granivorous birds such as the queleas in Africa are among the most numerous birds in the world and foraging flocks can cause devastation. Many insectivorous birds are also noted as beneficial in agriculture. Many early studies on the benefits or damages caused by birds in fields were made by analysis of stomach contents and observation of feeding behaviour. Modern studies aimed to manage birds in agriculture make use of a wide range of principles from ecology. Intensive aquaculture has brought humans in conflict with fish-eating birds such as cormorants.

Large flocks of pigeons and starlings in cities are often considered as a nuisance and techniques to reduce their populations or their impacts are constantly innovated. Birds are also of medical importance and their role as carriers of human diseases such as Japanese Encephalitis, West Nile Virus and H5N1 have been widely recognised. Bird strikes and the damage they cause in aviation are of particularly great importance, due to the fatal consequences and the level of economic losses caused. It has been estimated that the airline industry incurs worldwide damages of US $ 1.2 billion each year.

Many species of birds have been driven to extinction by human activities. Bird conservation requires specialized knowledge in aspects of biology, ecology and may require the use of very location specific approaches. Ornithologists contribute to conservation biology by studying the ecology of birds in the wild and identifying the key threats and ways of enhancing the survival of species. Critically endangered species such as the California Condor have had to be captured and bred in captivity. Such ex-situ conservation measures may be followed by re-introduction of the species into the wild.

Edward Grey Institute of Field Ornithology

The Edward Grey Institute of Field Ornithology (EGI), at Oxford University, England is an academic body which conducts research in ornithology and the general field of evolutionary ecology and conservation biology, with an emphasis on understanding organisms in natural environments. It is named in honour of Edward Grey, 1st Viscount Grey of Fallodon, a notable politician and ornithologist.

The Institute houses the Alexander Library, the best ornithological library in Europe and one of the best in the world, which is named after W. B. Alexander.

The first Director of the fledgling Institute was W.B. Alexander, remembered in the name of the EGI's library, the Alexander Library. Alexander was succeeded in 1945 by former school-teacher David Lack, one of the pioneers of population biology, who had already published The Life of the Robin. Lack served as Director until his death in 1973, and oversaw the growth of the EGI into an internationally known centre for research in to population biology of birds.

Lack was succeeded by Chris Perrins in 1974, who continued as Director until his official retirement in 2002. During this time, work in the EGI expanded from the field of population biology to encompass the new field of Behavioural Ecology, with John Krebs and Nick Davies (then at Oxford, now Professor of Behavioural Ecology at Cambridge) co-authoring the textbooks which defined the field. The EGI was also the centre for work on Birds of the Western Palearctic, up to its completion in 1990s, and became increasingly important as a training centre for ornithologists who went on to play important roles in Conservation.

Following Chris Perrins's retirement, a major endowment in honour of Dr Luc Hoffmann's eightieth birthday led to the establishment of the Luc Hoffmann Chair in Field Ornithology. Ben Sheldon was elected as the first holder of this chair, and as Director of the EGI in 2004.

By the end of 2006, a total of 165 DPhil students had successfully defended their theses based on work carried out at the EGI; this number is at least matched by the number of postdoctoral and other research visitors who have spent time at the Institute. Scientific research work on birds has been conducted on all continents, and the major research themes of the EGI, population and evolutionary ecology of birds, have been supplemented by a very wide range of research activities.

Yamashina Institute for Ornithology

The Yamashina Institute for Ornithology (山階鳥類研究所 ,Yamashina Chōruikenkyūsho?) is a non-profit scientific research organization in Japan, specializing in ornithology studies.

The Yamashina Institute for Ornithology was founded by Dr. Yoshimaro Yamashina at his home in Shibuya, Tokyo as a private museum to store his collection of bird specimens and books. Marquis Yamashina was the second son of Prince Yamashina Kikumaro. He opened his museum to the public in 1942. At the Institute, Yamashina conducted research into bird taxonomy based on chromosomes, and wrote numerous technical journal articles and books on ornithology.

The Institute relocated to its present location approximately 30 kilometer east of Tokyo at Abiko, Chiba in 1984. The Institute has maintained close ties to the Imperial Family of Japan. It is chaired by HIH Prince Akishino, younger brother to the Crown Prince Naruhito of Japan, and their younger sister Princess Sayako worked as a researcher at the Institute from 1992-2005, where she specialized in the study of kingfishers.

The Yamashina Institute publishes several journals and reports, including the Journal of the Yamashina Institute for Ornithology, the annual Report of the Bird Migration Research Center and a monthly newspaper for support group members.

The Institute also sponsors a biannual Yamashina Yoshimaro Memorial Ornithological Award to an individual or group who has made remarkable contributions to the development ornithology or the protection of birds.

Cornell Laboratory of Ornithology

Ivory-billed woodpecker

The Cornell Lab of Ornithology is an institute whose mission is “To interpret and conserve the earth’s biological diversity through research, education, and citizen science focused on birds.” The lab is associated with Cornell University and has several faculty on site as well as nonfaculty directors, students, and a large staff of scientists, educators, web developers, communications and marketing specialists, and program administrators. The lab is focused mainly on birds, but also does research, more generally, on biological diversity; specific programs include citizen science, bird population studies, a bioacoustics research program, an evolutionary biology program, and the Macaulay Library, the largest collection of animal sounds in the world, with more than 160,000 recordings and a growing archive of natural history video--many now included in the Birds of North America online resource. Citizen science projects include Project FeederWatch, NestWatch, eBird, Celebrate Urban Birds, The Great Backyard Bird Count, The House Finch Disease Survey, Birds in Forested Landscapes, and the virtual citizen science project, CamClickr. Together, the lab's citizen science projects engage more than 200,000 people across North America and beyond. The lab is located in the Sapsucker Woods in Ithaca, New York, and includes trails that are open 365 days a year.

The lab's main library, the Adelson Library, part of the Cornell University Library system, contains historical and contemporary ornithological materials, including an extensive collection of monographs and journals.

In the spring of 2005, the Cornell Lab of Ornithology announced that the Ivory-billed Woodpecker, thought to have been extinct for decades, had been rediscovered in Arkansas. They presented a video as evidence. This was challenged by a team led by David A. Sibley and by Jerome Jackson of Florida Gulf Coast University. They identified the bird of the video as a Pileated Woodpecker. The Cornell Lab of Ornithology rebuffed these claims in return. The debate is still ongoing about the existence of the Ivory-billed Woodpecker.
