The southern fiscal or fiscal shrike (Lanius collaris) is a member of the shrike family found through most of southern Africa. It is also sometimes named jackie hangman or butcher bird due to its habit of impaling its prey on acacia thorns to store the food for later consumption. It was previously lumped together with the northern fiscal (Lanius humeralis). [2] Together they were known as the common fiscal.
In 1760 the French zoologist Mathurin Jacques Brisson included a description of the southern fiscal in his Ornithologie based on a specimen collected from the Cape of Good Hope in South Africa. He used the French name La pie-griesche du Cap de Bonne Espérance and the Latin Lanius capitis Bonae Spei. [3] Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. [4] When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he added 240 species that had been previously described by Brisson. [4] One of these was the southern fiscal. Linnaeus included a brief description, coined the current binomial name Lanius collaris and cited Brisson's work. [5] The specific name collaris is Latin for "of the neck". [6]
Five subspecies are recognised. [7]
This is a fairly distinctive 21–23-cm long passerine with white underparts and black upperparts extending from the top of the head down to the tail. The bird has a characteristic white "V" on the back and a relatively long black tail with white outer feathers and white tips on the other feathers. The bill, eyes and legs are black. Adult male and female common fiscals are quite similar except for the rufous lower flank of the female.
The calls are a jumbled mix of shrike-like swizzling sounds including some imitations and a harsh Dzzzttt-dzzzt-dzzzt alarm call. Most of those calls however are either threatening or alarm calls. The species sometimes produces a surprisingly sweet, quiet song, although such song, however sweet it sounds, generally is either territorial or pair-bonding in function. [8]
The southern fiscal lives in a wide range of habitats from grassland with fences for perching to acacia thornveld or even woodland, but avoids very dense habitats where its hunting would be impaired.
Southern fiscals can encounter cold temperatures in the winter and in high-altitude environments. To cope with these cold temperatures, fiscal shrikes undergo seasonal changes in body temperature, oxygen consumption, and evaporative water loss in order to conserve energy. At lower altitudes, the shrikes have higher basal metabolic rates, evaporative water loss, and body temperatures compared to shrikes in higher altitude environments. In the winter, basal metabolic rate and oxygen consumption are increased while body temperature is decreased. [9]
The southern fiscal is usually solitary and hunts insects and small rodents from an exposed perch or the tops of shrubs. Territorial size is directly related to the density of hunting perches. Installing more artificial perches causes the fiscal to reduce its territory size and allow more birds in the affected range.
In eastern Africa, the southern fiscal is a major predator of the plain tiger butterfly. [10]
Along with adjusting their physiology, southern fiscals also adjust their hunting methods at different times of year in response to seasonal changes in food demand. During the summer, the shrikes hunted from an hour before sunrise to right before sunset. During the winter, hunting only occurred from daytime to sunset, so the shrikes increased their attack and capture rates, and they also captured larger prey. Prey length, handling time, and attack time increased with altitude. [11]
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 woodchat shrike is a member of the shrike family Laniidae. It can be identified by its red-brown crown and nape. It is mainly insectivorous and favours open wooded areas with scattered trees such as orchards, particularly when there is bare or sandy ground. The woodchat shrike breeds in southern Europe, the Middle East and northwest Africa, and winters in tropical Africa.
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 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.
The mosque swallow is a large swallow. It is a resident breeder in much of sub-Saharan Africa, although most common in the west. It does not migrate but follows the rains to some extent.
The black-crowned tchagra is a bushshrike. This family of passerine birds is closely related to the true shrikes in the family Laniidae, and was once included in that group.
The olive bee-eater or Madagascar bee-eater is a near passerine bee-eater species in the genus Merops. It is native to the southern half of Africa where it is present in Angola; Botswana; Burundi; Comoros; Democratic Republic of the Congo; Djibouti; Eritrea; Ethiopia; Kenya; Madagascar; Malawi; Mayotte; Mozambique; Namibia; Rwanda; Somalia; South Sudan; Sudan; Tanzania; Uganda; Zambia; Zimbabwe. It is a common species with a wide range so the International Union for Conservation of Nature has rated their conservation status as "least concern".
The lilac-breasted roller is an African bird of the roller family, Coraciidae. It is widely distributed in Southern and Eastern Africa, and is a vagrant to the southern Arabian Peninsula. It prefers open woodland and savanna, and it is for the most part absent from treeless places. Usually found alone or in pairs, it perches at the tops of trees, poles or other high vantage points from where it can spot insects, amphibians and small birds moving about on the ground. Nesting takes place in a natural hole in a tree where a clutch of 2–4 eggs are laid, and incubated by both parents, who are extremely aggressive in defence of their nest, taking on raptors and other birds. During the breeding season the male will rise to a fair height, descending in swoops and dives, while uttering harsh, discordant cries. The sexes are different in coloration, and juveniles lack the long tail streamers of adults. This species is unofficially considered the national bird of Kenya. Alternative names for the lilac-breasted roller include the fork-tailed roller, lilac-throated roller and Mosilikatze's roller.
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 southern boubou is a bushshrike. Though these passerine birds and their relations were once included with true shrikes in the Laniidae, they are not closely related to that family.
The Cape batis is a small, stout insect-eating passerine bird in the wattle-eye family. It is endemic to the Afromontane forests of southern Africa.
The violet-eared waxbill or common grenadier is a common species of estrildid finch found in drier land of Southern Africa.
The Cape starling, also known as red-shouldered glossy-starling or Cape glossy starling, is a species of starling in the family Sturnidae. It is found in Southern Africa, where it lives in woodlands, bushveld and in suburbs.
The Senegal batis is a species of small passerine bird in the wattle-eyes family, Platysteiridae. It occurs in western Africa where it is found in dry savanna and subtropical or tropical dry shrubland. It was originally given the binomial name Muscicapa senegalensis by Carl Linnaeus in 1766.
The long-tailed fiscal is a species of bird in the shrike family Laniidae. The species is closely related to the more widespread grey-backed fiscal and is sometimes placed in a separate subgenus, Neolanius, with that species. It is found in southern Somalia, southern and south-eastern Kenya, from the shores of Lake Victoria to the coast; and northern and eastern Tanzania south to Dar es Salaam, with a separate population at Usanga Flats. Its natural habitat is open dry habitats such as dry, treeless savanna, open woodland and cultivated patches.
The Somali fiscal is a species of bird in the family Laniidae. Other common names include the Karoli fiscal, the Somali fiscal shrike and the Somali shrike. The bird is found in Djibouti, Ethiopia and Somalia in the Horn of Africa, as well as in Kenya in the African Great Lakes region. Its natural habitat is subtropical or tropical dry shrubland.
The magpie shrike, also known as the African long-tailed shrike, is a species of bird in the family Laniidae. It is native to the grasslands of eastern and southeastern Africa, where its natural habitats are dry savannah, moist savannah, and subtropical or tropical dry shrubland. It has a very wide range and is common in places, and the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
The northern fiscal is a member of the shrike family found through most of Sub-Saharan Africa. It used to be grouped with the southern fiscal. Together they were called the common fiscal. The fiscal gets its English and Afrikaans common names from its black and white 'suit-and-tie' appearance reminiscent of the taxman (‘fiscal’).
