The ring ouzel is a mainly European member of the thrush family Turdidae. It is a medium-sized thrush, 23–24 centimetres (9.1–9.4 in) in length and weighing 90–138 grams (3.2–4.9 oz). The male is predominantly black with a conspicuous white crescent across its breast. Females are browner and duller than males, and young birds may lack the pale chest markings altogether. In all but the northernmost part of its range, this is a high-altitude species, with three races breeding in mountains from Ireland east to Iran. It breeds in open mountain areas with some trees or shrubs, the latter often including heather, conifers, beech, hairy alpenrose or juniper. It is a migratory bird, leaving the breeding areas to winter in southern Europe, North Africa and Turkey, typically in mountains with juniper bushes. The typical clutch is 3–6 brown-flecked pale blue or greenish-blue eggs. They are incubated almost entirely by the female, with hatching normally occurring after 13 days. The altricial, downy chicks fledge in another 14 days and are dependent on their parents for about 12 days after fledging.
The Eurasian tree sparrow is a passerine bird in the sparrow family with a rich chestnut crown and nape, and a black patch on each pure white cheek. The sexes are similarly plumaged, and young birds are a duller version of the adult. This sparrow breeds over most of temperate Eurasia and Southeast Asia, where it is known as the tree sparrow, and it has been introduced elsewhere including the United States, where it is known as the Eurasian tree sparrow or German sparrow to differentiate it from the native unrelated American tree sparrow. Although several subspecies are recognised, the appearance of this bird varies little across its extensive range.
The Lapland longspur, also known as the Lapland bunting, is a passerine bird in the longspur family Calcariidae, a group separated by most modern authors from the Fringillidae.
Cassin's finch is a bird in the finch family, Fringillidae. This species and the other "American rosefinches" are placed in the genus Haemorhous.
Marmaduke Tunstall was an English ornithologist and collector. He was the author of Ornithologica Britannica (1771), probably the first British work to use binomial nomenclature.
The Polish Academy of Sciences is a Polish state-sponsored institution of higher learning. Headquartered in Warsaw, it is responsible for spearheading the development of science across the country by a society of distinguished scholars and a network of research institutes. It was established in 1951, during the early period of the Polish People's Republic following World War II.
The Italian sparrow, also known as the cisalpine sparrow, is a passerine bird of the sparrow family Passeridae, found in Italy and other parts of the Mediterranean region. In appearance, it is intermediate between the house sparrow, and the Spanish sparrow, a species of the Mediterranean and Central Asia closely related to the house sparrow. The Italian sparrow occurs in northern Italy and neighbouring regions, with intermediates with the house sparrow in a very narrow contact zone in the Alps, a slow gradation in appearance from the Italian to Spanish sparrows across central and southern Italy, and more birds of intermediate appearance in Malta, Crete, and other parts of the Mediterranean.
The African blue tit is a species of bird in the family Paridae. It is found in northern Africa, Pantelleria (Italy) and the Canary Islands (Spain). Its natural habitat is temperate forests. This species and the Eurasian blue tit were formerly considered conspecific. The status of this species has not been assessed because it is noted to be common on the islands of Tenerife and Gran Canaria. The species has been used in many research studies due to its island populations and relevance to evolutionary hypotheses.
The great-billed seed finch is a species of bird in the family Thraupidae. Its natural habitats are subtropical or tropical moist shrubland, swamps, and heavily degraded former forest. They are found in two separate general populations, one in the northern Amazon rainforest and the other in the Cerrado. They live in flooded areas with nests low to the ground. The adults express strong sexual dimorphism. Males are black with white under wing-coverts and ivory white bills, and the females are generally light brown with white under wing-coverts and black bills. Both the male and female have very large, thick bills. The great-billed seed finch has a melodious call, which has made it a target for trapping.
The Himalayan flameback, also known as the Himalayan goldenback, is a species of bird in the family Picidae. At the moment very little is known of this species and more fieldwork is required. The Himalayan flameback is not threatened but it is suspected that deforestation could severely affect the species population.
Richard Schodde, OAM is an Australian botanist and ornithologist.
Acta Physica Polonica is an open access peer-reviewed scientific journal covering research in physics. It was established by the Polish Physical Society in 1920. In 1970 is split into two journals Acta Physica Polonica A and Acta Physica Polonica B. The two journals became independent in 1995, with series A published by the Institute of Physics of the Polish Academy of Sciences and series B published by the Jagiellonian University in cooperation with the Polish Academy of Arts and Sciences.
Palaeortyx is an extinct genus of granivorous galliform bird that lived 28.4 to 2.588 million years ago. It lived from the early Eocene to the early Pliocene, and may be a phasianid or odontophorid. It is known from several fossils found in Germany, France, Italy, Hungary and Romania.
Acta Palaeontologica Polonica is a quarterly peer-reviewed open access scientific journal of paleontology and paleobiology. It was established by Roman Kozłowski in 1956. It is published by the Institute of Paleobiology of the Polish Academy of Sciences and edited by Richard L. Cifelli and Jarosław Stolarski.
The African hoopoe is a species of hoopoe in the family Upupidae. Previously considered as a subspecies of the Eurasian hoopoe, it is a resident species of southern Africa.
Władysław Rydzewski was a Polish professor of zoology who specialized in ornithology and founded the journal The Ring in 1954. Władysław Rydzewski Museum of Natural History in Wroclaw was named in his honour.
Andrzej Stanisław Julian Dunajewski was a Polish zoologist and ornithologist.
Tatiana Borisovna Ardamatskaya was a Soviet-Ukrainian ornithologist and conservationist. She is known for her research on waterbirds and coastal birds of the Ukrainian Black Sea region and for her efforts to improve environmental protections for them. Her studies included Mediterranean gulls, swans, eiders, ducks, geese, and terns, among others.
Albrecht Manegold is a German ornithologist and paleontologist. He is the curator of the vertebrate collection at the State Museum of Natural History Karlsruhe. He is known for contributions to the study of early passerine evolution. He has described extinct passerines and piciformes including the fossil treecreeper Certhia rummeli and the fossil woodpecker Australopicus nelsonmandelai.
