Timothy Robert Birkhead FRS [4] (born 1950) is a British ornithologist. He has been Professor of Behaviour and Evolution at the University of Sheffield [5] [6] since 1976. [7]
Birkhead was awarded a Bachelor's degree in Biology from Newcastle University in 1972, followed by a Doctor of Philosophy degree from University of Oxford in 1976 for research on the breeding biology and survival of guillemots Uria aalge supervised by E.K. Dunn and Chris Perrins. [3] He was subsequently awarded a Doctor of Science from Newcastle in 1989. [1]
Birkhead's research on promiscuity in birds redefined the mating systems of birds.[ citation needed ] Focusing initially on the adaptive significance of male promiscuity and female promiscuity, he later switched to the study of mechanisms and resolved the mechanisms of sperm competition in birds. He provided some of the first evidence of: cryptic female choice in birds; strategic sperm allocation, and he also provided the first estimates of the quantitative genetics of sperm traits in birds.[ citation needed ]
Birkhead's research also resolved the issue of polyspermy in birds and provided the first evidence for morphological sperm selection in the female reproductive tract. [8] His long term study of the population biology of common guillemots on the island of Skomer off Wales has run since 1972, and is currently in need of support. [9] [10]
His recent research is on the adaptive significance of egg shape in birds, including the common guillemot whose pyriform egg has long been thought to allow it to either spin-like- a-top or roll-in-an-arc to prevent it rolling off the cliff ledge. However, there is no evidence for either of these ideas. [11] [12] Instead, Birkhead and colleagues have identified the main advantage of a pyriform shape: stability. The pyriform shape makes the egg inherently more stable, especially on the sloping surfaces on which guillemots commonly breed. [13]
Birkhead has combined his enthusiasm for research with a passion for undergraduate teaching. He has taught courses on ecology, evolution, statistics, birds, behavioural ecology, animal behaviour and the history and philosophy of science. His teaching has been recognised by four awards, including a National Teaching Fellowship in 2017. [2]
Starting in 1992 and continuing until 2015 (when he handed over to a steering group) Birkhead organised (with Professor Harry Moore) a small (~60) biennial meeting on reproductive biology in the Peak District National Park known as Biology of Spermatozoa (BoS). Delegates are from a diverse range of backgrounds and include clinicians, reproductive physiologists, andrologists, theoreticians and evolutionary biologists. The format and interdisciplinary nature of the meeting was successful in terms of exchanging ideas, techniques and establishing collaborations. [22]
Between 2002 and 2010 Birkhead had a monthly column in Times Higher Education . [23] His articles were concerned with various aspects of higher education: undergraduate teaching, administration and, occasionally, research.
He has written for The Guardian ,[ citation needed ] The Independent ,[ citation needed ] the BBC, The Biologist, Natural History and Evolve.[ citation needed ]
He has featured on numerous BBC Radio 4 programmes, including Start the Week — with Jeremy Paxman;[ when? ] The Life Scientific with Jim Al-Khalili; [24] The Infinite Monkey Cage in 2018.[ citation needed ] His book ‘The Most Perfect Thing’ provided the basis for the TV documentary ‘Attenborough’s Eggs’ introduced by David Attenborough (2018).[ citation needed ] Birkhead has been honorary curator of the Alfred Denny Museum in the University of Sheffield between 1980-2018. [25] [26]
He has given numerous public lectures, including at Café Scientique, the Cheltenham Science Festival and numerous literary festivals including Ways with Words (Sheffield) and Hay on Wye. His a TED (conference) lecture on the history of ornithology has been viewed over 100,000 times. [27]
Over the course of his career, Birkhead has received a number of awards:
The great auk is a species of flightless alcid that became extinct in the mid-19th century. It was the only modern species in the genus Pinguinus. It is not closely related to the birds now known as penguins, which were discovered later by Europeans and so named by sailors because of their physical resemblance to the great auk.
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.
An auk or alcid is a bird of the family Alcidae in the order Charadriiformes. The alcid family includes the murres, guillemots, auklets, puffins, and murrelets. The family contains 25 extant or recently extinct species that are divided into 11 genera.
Guillemot is the common name for several species of seabird in the Alcidae or auk family. In British use, the term comprises two genera: Uria and Cepphus. In North America the Uria species are called murres and only the Cepphus species are called "guillemots". This word of French origin derives from a form of the name William, cf. French: Guillaume.
The razorbill, razor-billed auk, or lesser auk is a North Atlantic colonial seabird and the only extant member of the genus Alca of the family Alcidae, the auks. It is the closest living relative of the extinct great auk.
The common murre or common guillemot is a large auk. It has a circumpolar distribution, occurring in low-Arctic and boreal waters in the North Atlantic and North Pacific. It spends most of its time at sea, only coming to land to breed on rocky cliff shores or islands.
Francis Willughby FRS was an English ornithologist and ichthyologist, and an early student of linguistics and games.
The thick-billed murre or Brünnich's guillemot is a bird in the auk family (Alcidae). This bird is named after the Danish zoologist Morten Thrane Brünnich. The very deeply black North Pacific subspecies Uria lomvia arra is also called Pallas' murre after its describer. The genus name is from Ancient Greek ouria, a waterbird mentioned by Athenaeus. The species term lomvia is a Swedish word for an auk or diver. The English "guillemot" is from French guillemot probably derived from Guillaume, "William". "Murre" is of uncertain origins, but may imitate the call of the common guillemot.
Professor Geoffrey Alan Parker FRS is an emeritus professor of biology at the University of Liverpool and the 2008 recipient of the Darwin Medal. Parker has been called “the professional’s professional”.
Christopher Miles Perrins, is Emeritus Fellow of the Edward Grey Institute of Field Ornithology at the University of Oxford, Emeritus Fellow at Wolfson College, Oxford and Her Majesty's Warden of the Swans since 1993.
In biology, polyspermy describes the fertilization of an egg by more than one sperm. Diploid organisms normally contain two copies of each chromosome, one from each parent. The cell resulting from polyspermy, on the other hand, contains three or more copies of each chromosome—one from the egg and one each from multiple sperm. Usually, the result is an unviable zygote. This may occur because sperm are too efficient at reaching and fertilizing eggs due to the selective pressures of sperm competition. Such a situation is often deleterious to the female: in other words, the male–male competition among sperm spills over to create sexual conflict.
Uria is a genus of seabirds in the auk family known in Britain as guillemots, in most of North America as murres, and in Newfoundland and Labrador as turr. These are medium-sized birds with mainly brown or black plumage in the breeding season. They breed on the coasts of the northern Atlantic and Pacific oceans.
Bird eggs are laid by the females and range in quantity from one to up to seventeen. Clutch size may vary latitudinally within a species. Some birds lay eggs even when the eggs have not been fertilized; it is not uncommon for pet owners to find their lone bird nesting on a clutch of infertile eggs, which are sometimes called wind-eggs.
The term seabird is used for many families of birds in several orders that spend the majority of their lives at sea. Seabirds make up some, if not all, of the families in the following orders: Procellariiformes, Sphenisciformes, Pelecaniformes, and Charadriiformes. Many seabirds remain at sea for several consecutive years at a time, without ever seeing land. Breeding is the central purpose for seabirds to visit land. The breeding period is usually extremely protracted in many seabirds and may last over a year in some of the larger albatrosses; this is in stark contrast with passerine birds. Seabirds nest in single or mixed-species colonies of varying densities, mainly on offshore islands devoid of terrestrial predators. However, seabirds exhibit many unusual breeding behaviors during all stages of the reproductive cycle that are not extensively reported outside of the primary scientific literature.

A History of the Birds of Europe, Including all the Species Inhabiting the Western Palearctic Region is a nine-volume ornithological book published in parts between 1871 and 1896. It was mainly written by Henry Eeles Dresser, although Richard Bowdler Sharpe co-authored the earlier volumes. It describes all the bird species reliably recorded in the wild in Europe and adjacent geographical areas with similar fauna, giving their worldwide distribution, variations in appearance and migratory movements.
The Max Planck Institute for Ornithology was a non-university research institution under the sponsorship of the Max Planck Society for the Advancement of Science (MPG). As of January 1st 2023, it merged with the Max Planck Institute for Neurobiology to form the new Max Planck Institute for Biological Intelligence. The institute is located in Seewiesen, which belongs to the municipality of Pöcking in Upper Bavaria. The institute’s focus was on basic scientific research in the fields of organismic biology, zoology, ornithology, neurobiology, behavioural ecology, evolutionary biology and evolutionary genetics. The institute is managed on a collegial basis, i.e. one of the two directors of the institute takes over the management for a certain time period. The last managing director was Manfred Gahr.
The Wonderful Mr Willughby: The First True Ornithologist is a 2018 biography, written by Tim Birkhead, about Francis Willughby (1635–1672), an English ornithologist, ichthyologist, entomologist, and Fellow of the Royal Society. Birkhead's work is the first book-length biography of Willughby.
