10584. Fieldfares (Turdus pilaris) nesting in the vicinity will also increase the desirability of nest sites to great grey shrikes, which moreover often refuse to prey upon these thrushes' nestlings though the opportunity is there. Size: Length 22–26 cm, weight 56–80 g. Nest: Often in pine trees, at a height averaging 2.5 metres above the ground. Grey Heron. These terms may mean "magpie killer", due to their use for luring carnivorous birds to hunters – but perhaps more likely "killer magpie", considering that the bird was believed to be a peculiar sort of magpie by Johann Leonhard Frisch and others, and that another vernacular English name was "murdering pie". Here in North America we have exactly two species of butcherbirds: the medium-sized Northern Shrike (also know as the Great Grey Shrike) and the somewhat smaller Loggerhead Shrike. Its stronghold is the region around Sweden, where at least almost 20,000, perhaps as many as 50,000 were believed to live in the late 20th century. At first, the female rebuffs the male, only allowing him to feed her. Eventually, the female will join in the male's displays, and the songs will become duets. The great grey shrike catches its prey and impales it on thorns or even barbed-wire fences Bird then rips its prey, which can be a rodent, bird or insect, limb from limb - often saving some for later The feet are not suited for tearing up prey, however. It will usually stay low above the ground in flight, approaching perches from below and landing in an upward swoop. To seek out potential mates, males will venture outside their breeding territories. 60–61, 150–151, Harris & Franklin (2000): pp. The type locality of Linnaeus is simply given as Europa ("Europe"). Group neighbours will respond by performing the same type of flight, and eventually about half the group's members will depart to the meeting location where they will spend several tens of minutes – sometimes more than an hour – chattering, calling, duetting, and excitedly moving about the meeting site (which typically is some small tree or shrubbery). The increase and decline seem to be reactions to changing land use, with an increase as the number of agricultural workers declined after World War II and land fell fallow, declining again when land consolidation (see e.g. [19], The Iberian grey shrike (L. meridionalis) was formerly included in the great grey shrike as subspecies. Diet: Large insects and small birds and animals. [31][34], Great grey shrikes breed during the summer, typically once per year. [9] A whimsical name – presumably from Scotland or nearby England – was "white wisky John" in reference to its wavy and somewhat unelegant flight, during which its large areas of light plumage are conspicuous. 637, 1000, Swainson (2008): p. 47, Gessner (1555): p. 557, Aldrovandi (1646), Willughby (1676): pp. The interior cup is 8–12 cm (3.1–4.7 in) in diameter and 10–15 cm (3.9–5.9 in) deep; it is lined with fine twigs and roots, lichen, hair and feathers. Adults moult on their breeding grounds before going on migration, or before the depth of winter if they are resident. The cup nest is quite sizable, measuring 20–28 cm (7.9–11.0 in) in outer diameter. Prey animals may exceptionally be almost as large as the birds themselves, for example chicks of the willow ptarmigan (Lagopus lagopus) or a young stoat. Birds are generally of little importance however, except in spring when male songbirds are engaged in courtship display and often rather oblivious of their surroundings, in late summer when inexperienced fledglings abound, and in winter when most small mammals hibernate. Low German Neghen-doer and Middle German Nünmörder were also used; this has today evolved into Neuntöter and specifically means the red-backed shrike, but could in earlier times refer to any native Lanius. The centre of this group's radiation is probably in the eastern Mediterranean region, and the southern grey shrike represents the basalmost form. Their wings are black with large white patches on the wing coverts. It occurs in south western Europe (Iberian Peninsula and France). Licence: CC 3.0). They range in length from 22 to 26 cm, with a wingspan of 30 to 36 cm. 58–59, 66–67, 151, 10.2305/IUCN.UK.2017-3.RLTS.T103718932A118776098.en, "Northern Shrike, Life History, All About Birds – Cornell Lab of Ornithology", "Effects of Little Owl Predation on Northern Shrike Postfledging Success", Der V.ten Hauptart II.te Abtheilung, Viererley Arten Aelstern – II.te Platte, "A preliminary list of the birds of Seneca County, Ohio", "Identification of the Great Grey Shrike complex in Europe",, Wikipedia articles needing factual verification from September 2009, Lang and lang-xx code promoted to ISO 639-1, Articles containing Middle English (1100-1500)-language text, Articles containing Swedish-language text, Articles containing Icelandic-language text, Articles containing Norwegian-language text, Wikipedia articles needing factual verification from January 2011, Articles with dead external links from January 2020, Articles with permanently dead external links, Creative Commons Attribution-ShareAlike License, This page was last edited on 25 January 2021, at 15:07. Its northern limit is generally 70° northern latitude. The migrations are triggered by scarcity of food and therefore, according to prey population levels, the winter range might little extend south beyond the breeding range, or be entirely parapatric to it. The more excited the birds become, the higher and faster the calls get, via chek-chek-chek to a rattle trr-trr-trr or an explosive aak-aak-aak. There do not appear to be breeding records from the entire Kamchatka Peninsula; in Switzerland, the present day Czech Republic and southern Germany small populations were found in the mid-20th century but have declined or even disappeared since then. In particular the breast is usually darker and sometimes browner than the rest of the light underside, and may appear as an indistinct band between the lighter belly and white throat. The latter is larger and generally differs from the northern species as the southern does, and in addition has much larger white areas in wings and tail. © Copyright: Images: Sometimes known in Finnish as Lapland Magpies, Great Grey Shrikes are long-tailed thrush-sized birds with strong, thick-set beaks. Across its range, the young acquire the adult plumage in their first spring. Linnaeus' binomial name replaced the cumbersome and confusing descriptive names of the earlier naturalist books he gives as his sources: in his own Fauna Svecica he named it ampelis caerulescens, alis caudaque nigricantibus ("light-blue waxwing, wings and tail blackish"), while it is called pica cinerea sive lanius major ("ash-grey magpie or greater shrike") by Johann Leonhard Frisch, who in his splendid colour plate confused male and female. It forms a superspecies with its parapatric southern relatives, the Iberian grey shrike (L. meridionalis), the Chinese grey shrike (L. sphenocerus) and the American loggerhead shrike (L. ludovicianus). The Great Grey Shrike Lanius excubitor, as well as other species of family Laniidae, re-cognise humans as potential predators and actively defend nests. Migration: By day. In social interactions, birds signal an aggressive stance by a bold upright posture, fanning and then flicking the tail and eventually the wings also as the bird gets more excited. When presenting nesting sites, males give the variety of calls described above and jerk their head and fanned tail. Wherever it occurs, its numbers are usually many hundreds or even thousands per country. [34][36], Common cuckoos (Cuculus canorus) have been noted as regular brood parasites of L. e. excubitor in the past; for reasons unknown this has ceased since the late 1970s or so. In exceptionally good conditions, they raise two broods a year, and if the first clutch is destroyed before hatching they are usually able to produce a second one. [7] The common English name "shrike" is from Old English scríc, "shriek", referring to the shrill call.[8]. Menu. [31][33], The basic metabolic rate of the great grey shrike is around 800 milliwatts, or somewhat more than 11 milliwatts per gram of body mass. Great grey shrikes are medium-sized, about the same size as thrushes and mockingbirds. Its body is constructed of coarse vegetable material – mainly large twigs and chunks of moss, though bits of fabric and rubbish may be added. Various contact calls have been described as chlie(p), gihrrr, kwä or wuut. Their cheeks, chin and the stripe above their eyes are white. The lesser grey shrike (L. minor, Balkans to Central Asia) seems to be quite distinct indeed and is sympatric with the grey shrike superspecies between Eastern Europe and Central Asia; it may be more closely related to the small brown shrikes and resemble the bold, aggressive and hard-to-catch grey shrikes because of Batesian mimicry. Finnish breeding population estimated at 6,000–9,000 pairs. Occasionally bats, newts and salamanders, and even fish are eaten. Linnaeus chose his specific name because the species "observes approaching hawks and announces [the presence] of songbirds"[6] as he put it. Regularly Occurring Species. They measure around 26 mm (1.0 in) in length and 19.5 mm (0.77 in) in width. Shrikes. The few dozen in the Netherlands and the 10 birds or so in Denmark might disappear because of a few years of adverse circumstances. Shrike, meanwhile, is of Germanic origin also and dates back at least to Middle or Early Modern English schricum. As to size, GGS is listed in the Collins guide as 21-26 cms in length, whereas Mistle Thrush is 26-29 cms, so biggest GGS just about equals smallest Mistle Thrush. 11152. On the wintering grounds, pairs separate to account for the lower amount of food available at that time, but if both members migrate they tend to have their wintering grounds not far apart. Apparently, the two species are more efficient in spotting potential nest predators – in particular corvids – early on and mobbing them off cooperatively than either is on its own. The song becomes softer and more warbling as the male shows the female around his territory, and at potential nest sites the male gives a lively chatter containing fluting tli-tli, prrr trills and kwiw...püh calls. Shop high-quality unique Shrike T-Shirts designed and sold by artists. around Frankfurt/Main and Strasbourg) probably mean "choking angel" (cf. 24–25, Sangster, Harris & Franklin (2000): pp. In Europe, the breeding population has estimated to number c.69,000-176,000 pairs (BirdLife International 2015). But most authors cited by Linnaeus – Eleazar Albin, Ulisse Aldrovandi, John Ray and Francis Willughby – called it lanius cinereus major or similar, which is a near-literal equivalent of the common name "great grey shrike". The Red-backed Shrike was once a common bird across southern Britain, but has disappeared with the intensification of agricultural practices, though it is still seen on passage. Flies south September–October, returning in April. Feeding bird in winter. The courtship period is generally longer than in the Iberian grey shrike (L. meridionalis), usually starting about March and lasting to April/May. [21], The Iberian grey shrike is clearer and usually darker grey above, and not tinged grey but often decidedly pinkish on the belly and particular breast; the white "eyebrow" extends to over the beak, which has typically a larger pale base. The illustrations on the highly variable Long-tailed Shrike are also very thorough. The better examples include the Great Grey (Northern) Shrike and the Southern Grey Shrike. Taipan. In this, they have almost a one-in-three chance of success, and consequently the average grey shrike nest is very likely to contain offspring of more than one male. In less productive habitat, "floaters" hold territories more ephemerally. [38] The maximum documented lifespan, however, is 12 years. Shrikes are medium-sized birds with grey, brown, or black and white plumage. The scapulars (shoulder feathers) are white, and the wings are black with a white bar made up by the bases of the primary remiges, continuing slightly offset onto the bases of the secondary remiges in some regions. [31], The flight of the great grey shrike is undulating and rather heavy, but its dash is straight and determined. Large arthropods are the second-most important prey by quantity, though not by biomass; in the latter respect they are only a bit more important than birds, except as food for nestlings where they usually form a substantial part of the diet. They have a dark mask from their beak to their cheeks. What's new. If you live in the northern United States, you can see the Loggerhead Shrike in summer and the Northern Shrike in winter (they breed up in the taiga and tundra). Parents may behave very aggressively towards intruders near nest. Alternatively, it may scan the grassland below from flight, essentially staying in one place during prolonged bouts of mainly hovering flight that may last up to 20 minutes. To beg for food – young to adults or mates to each other –, rows of waik calls are given. It will drop down in a light glide for terrestrial prey or swoop hawk-like on a flying insect. The English version, having become wariangle or weirangle, was eventually transferred to the native red-backed shrike (L. collurio) and lingered on into modern times in Yorkshire. The altricial nestlings hatch naked, blind and pink-skinned, weighing c. 4 g (0.14 oz); their skin turns darker after a few days. An adult of this species needs about 50 g (1.8 oz) of prey a day, probably somewhat more in winter. This is related to such words as Norwegian and Swedish skrika ("shriek, skrike"), German Schrei ("scream") or Icelandic shrikja ("shrieker"). The underparts are white, slightly tinged with grey in most subspecies. Surprisingly we don’t seem to have had a GGS yet this winter despite the v cold current weather, although of course the current restrictions mean that folk can’t/shouldn’t be able to get up to the usual haunts to check. Close-up of a Grey Shrike The red-backed shrike. The individual phrases may go like tu-tu-krr-pree-pree or trr-turit trr-turit.... To announce that it has become aware of someone straying into its territory – be it a female or male of its species or a large mammal – it gives long shrill raspy whistles like trrii(u) or (t')kwiiet. Great Grey Shrike (Lanius excubitor) Photo no. 52–53, Ray (1713), Swainson (2008): p. 47, Harris & Franklin (2000): pp. In the high mountains of the Altai-Tian Shan region, it ranges south perhaps as far as 42° northern latitude. Forums. [26], Except for the subspecies bianchii which is largely all-year resident, and subspecies excubitor in the temperate European parts of its range with their mild maritime climate, the species is a short-distance migrant. this full size shrike was carved out of lime (wood) and painted with acrylic paints, price £300 plus postage.SOLD. The populations of the Central Asian mountains mostly migrate downslope rather than southwards. The inside of their beak is pink and they probably lack spots or other prominent marks; the wattles at the corners of the mouth are yellow as in many passerines. Fledglings remain in nest for 19–20 days. Other adults have occasionally been recorded assisting in feeding a pair's offspring; it is not clear whether these helpers at the nest are offspring of previous years, or unrelated non-breeding "floaters" or breeding neighbours. Great Grey Shrike Lanius excubitor. Males give increasingly vocal displays and show off the white markings of the wings in flight and of the tail by fanning it and turning away from the female. The long-tailed shrike or rufous-backed shrike is a member of the bird family Laniidae, the shrikes. Will preserve surplus food by impaling prey on thorny plants. Females are more prone to migration than males; they do not appear to migrate, on average, longer or shorter distances than males, and consequently are the dominant sex in many parts of the winter range. While the male may briefly take over incubating, his task during this time is to provide food. Carrion and berries are rarely if ever eaten; though it might occasionally plunder songbird nests this is not well documented and it is not known to eat eggs. They weigh between 48 and 80 g, however, most range between 60 and 70 g. Their upper parts are pearl grey. For these reasons the species is evaluated as Least Concern. A softer whistle goes like trüü(t). As it seems, once an individual great grey shrike has found a wintering territory it likes, it will return there subsequently and perhaps even try to defend it against competitors just like a summer territory. It typically weighs around 60 to 70 g (2.1 to 2.5 oz), although some subspecies are noticeably smaller or larger, and even in the nominate subspecies adult weights between 48 and 81 g (1.7 and 2.9 oz) are recorded. [17], The male's song consists of short pleasant warbling strophes, interspersed with fluid whistles. As moult requires a considerable investment of energy, some significant evolutionary benefits to offset this are likely. Distribution: A scarce breeder found in all parts of mainland Finland in semi-open habitats, most often around bogs. The phenomenon is not well understood, however. In Norway a vernacular name for the bird is varsler. To hunt, this bird perches on the topmost branch of a tree, utility pole or similar elevated spot in a characteristic upright stance some metres/yards (at least one and up to 18 m/20 yd) above ground.
