Shrikes are passerine birds of the family Laniidae. The family is composed of 34 species in two genera.
The great grey shrike is a large and predatory songbird species in the shrike family (Laniidae). It forms a superspecies with its parapatric southern relatives, the Iberian grey shrike, the Chinese grey shrike and the American loggerhead shrike. Males and females are similar in plumage, pearly grey above with a black eye-mask and white underparts.
The Iberian grey shrike is a member of the shrike family. It is closely related to the great grey shrike, Lanius excubitor, and its plumage is generally similar to the great grey shrike apart from the differences noted below. The Iberian was previously considered conspecific with the great grey; where they co-occur, they do not interbreed and are separated by choice of habitat.
The lesser grey shrike is a member of the shrike family Laniidae. It breeds in South and Central Europe and western Asia in the summer and migrates to winter quarters in southern Africa in the early autumn, returning in spring. It is a scarce vagrant to western Europe, including Great Britain, usually as a spring or autumn erratic.
The long-tailed shrike or rufous-backed shrike is a member of the bird family Laniidae, the shrikes. They are found widely distributed across Asia and there are variations in plumage across the range. The species ranges across much of Asia, both on the mainland and the eastern archipelagos. The eastern or Himalayan subspecies, L. s. tricolor, is sometimes called the black-headed shrike. Although there are considerable differences in plumage among the subspecies, they all have a long and narrow black tail, have a black mask and forehead, rufous rump and flanks and a small white patch on the shoulder. It is considered to form a superspecies with the grey-backed shrike which breeds on the Tibetan Plateau.
The loggerhead shrike is a passerine bird in the family Laniidae. It is the only member of the shrike family endemic to North America; the related northern shrike occurs north of its range, however it is also found in Siberia. It is nicknamed the butcherbird after its carnivorous tendencies, as it consumes prey such as insects, amphibians, lizards, small mammals and small birds, and some prey end up displayed and stored at a site, for example in a tree. Due to its small size and weak talons, this predatory bird relies on impaling its prey upon thorns or barbed wire for facilitated consumption. The numbers of loggerhead shrike have significantly decreased in recent years, especially in Midwestern, New England and Mid-Atlantic areas.
The grey wagtail is a member of the wagtail family, Motacillidae, measuring around 18–19 cm overall length. The species looks somewhat similar to the yellow wagtail but has the yellow on its underside restricted to the throat and vent. Breeding males have a black throat. The species is widely distributed, with several populations breeding in Eurosiberia and migrating to tropical regions in Asia and Africa. The species is always associated with running water when breeding, although they may use man-made structures near streams for the nest. Outside the breeding season, they may also be seen around lakes, coasts and other watery habitats. Like other wagtails, they frequently wag their tail and fly low with undulations and they have a sharp call that is often given in flight.
The fox sparrow is a large New World sparrow. It is the only member of the genus Passerella, although some authors split the species into four.
The brown shrike is a bird in the shrike family that is found mainly in Asia. It is closely related to the red-backed shrike and isabelline shrike. The genus name, Lanius, is derived from the Latin word for "butcher", and some shrikes are also known as "butcher birds" because of their feeding habits. The specific cristatus is Latin for "crested", used in a broader sense than in English. The common English name "shrike" is from Old English scríc, "shriek", referring to the shrill call.
Lanius, the typical shrikes, are a genus of passerine birds in the shrike family Laniidae. The majority of the family's species are placed in this genus. The genus name, Lanius, is derived from the Latin word for "butcher", and some shrikes are also known as "butcher birds" because of their feeding habits. The common English name "shrike" is from Old English scríc, "shriek", referring to the shrill call.
The tiger shrike or thick-billed shrike is a small passerine bird which belongs to the genus Lanius in the shrike family, Laniidae. It is found in wooded habitats across eastern Asia. It is a shy, often solitary bird which is less conspicuous than most other shrikes. Like other shrikes it is predatory, feeding on small animals. Its nest is built in a tree and three to six eggs are laid.
The golden-crowned sparrow is a large New World sparrow found in the western part of North America.
Harris's sparrow is a large sparrow. Their breeding habitat is the north part of central Canada, making it Canada's only endemic breeding bird. In the winter they migrate to the Great Plains states of the United States, from southern South Dakota to central Texas. The common name of this species commemorates the American amateur ornithologist Edward Harris (1799–1863).
Cracticus is a genus of butcherbirds native to Australasia. They are large songbirds, being between 30 and 40 cm (12–16 in) in length. Their colour ranges from black-and-white to mostly black with added grey plumage, depending on the species. They have a large, straight bill with a distinctive hook at the end which is used to skewer prey. They have high-pitched complex songs, which are used to defend their essentially year-round group territories: unlike birds of extratropical Eurasia and the Americas, both sexes sing prolifically.
The bull-headed shrike is a passerine bird of eastern Asia belonging to the shrike family Laniidae.
Emin's shrike is a species of passerine bird in the family Laniidae, the shrikes. This species has a scattered distribution across Africa from the Ivory Coast east to South Sudan and Uganda.
Prioksko-Terrasny Nature Biosphere Reserve is one of Russia's smallest zapovedniks, sprawling over an area of 5,000 hectares along the left bank of the Oka River in the Serpukhov District of Moskva Oblast. It was established in 1945 as part of the Moscow Nature Reserve and is home to 900 plant species, 130 bird species, and 54 mammal species. A wisent nursery was established in 1948 to populate the region with European bison from the Belovezhskaya Pushcha and Western Caucasus. There is also a small herd of American bison.
Interspecific feeding refers to behaviour reported in wild animals, particularly birds where adults of one species feed the young of another species. This usually excludes the case of birds feeding brood parasites. The behaviour has been of theoretical interest since it appears to be provide little evolutionary benefit to the feeding bird. Some researchers have suggested that it is mainly male birds that are lured into feeding a fledgling that begs.
The steppe grey shrike is a large subspecies of songbird in the shrike family (Laniidae) native to Central Asia and parts of northern China, Iran, Afghanistan and Pakistan. Formerly considered a subspecies of the southern grey shrike complex, it is now classified as a subspecies of the great grey shrike.
Alden Holmes Miller was an American ornithologist and director of the Museum of Vertebrate Zoology at the University of California, Berkeley for 25 years. He published over 250 papers on the biology, distribution, and taxonomy of birds, and served as president of the American Ornithologists' Union (1953-1955) and the International Commission on Zoological Nomenclature (1964-1965), and as editor of The Condor from 1939 until his death. He was a member of the National Academy of Sciences.
