The brown shrike (Lanius cristatus) is a bird in the shrike family that is found mainly in Asia. It is closely related to the red-backed shrike (L. collurio) and isabelline shrike (L. isabellinus). 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. [2] The common English name "shrike" is from Old English scríc, "shriek", referring to the shrill call. [3]

Contents

Like most other shrikes, it has a distinctive black "bandit-mask" through the eye and is found mainly in open scrub habitats, where it perches on the tops of thorny bushes in search of prey. Several populations of this widespread species form distinctive subspecies which breed in temperate Asia and migrate to their winter quarters in tropical Asia. They are sometimes found as vagrants in Europe and North America.

Taxonomy

In 1747 the English naturalist George Edwards included an illustration and a description of the brown shrike in the second volume of his A Natural History of Uncommon Birds. He used the English name "The Crested Red, or Russit Butcher-Bird". Edwards based his hand-coloured etching on a specimen that had been sent from Bengal to the silk-pattern designer Joseph Dandridge in London. [4] When in 1758 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the tenth edition, he placed the brown shrike with the other shrikes in the genus Lanius . Linnaeus included a brief description, coined the binomial name Lanius cristatus and cited Edwards' work. [5] The specific epithet is Latin meaning "crested" or "plumed". [6]

Four subspecies are recognised: [7]

Description

This shrike is mainly brown on the upper parts and the tail is rounded. The black mask can be paler in winter and has a white brow over it. The underside is creamy with rufous flanks and belly. The wings are brown and lack any white "mirror" patches. Females tend to have fine scalloping on the underside and the mask is dark brown and not as well marked as in the male. The distinction is not easy to use in the field but has been tested with breeding birds in Japan where the female can be identified from the presence of a brood patch. [8] The use of multiple measurements allows discrimination of the sex of about 90% of the birds. [9] Subspecies lucionensis has a grey crown shading into the brown upperparts and the rump appears more rufous than the rest of the upper back. [10] The tail is more brownish and not as reddish as in the red-backed shrike. [11] Younger birds of lucionensis have a brown crown and lack the grey on the head. Subspecies superciliosus has a broad white supercilium and a richer reddish crown. The tail is redder and tipped in white. [12] [13]

A number of confusing forms are known from central Asia where the populations of cristatus, isabellinus and collurio overlap. The taxonomy has been in a state of flux and some forms such as phoenicuroides formerly considered as subspecies of L. cristatus have been moved to the species L. isabellinus. [10] [14] Subspecies lucionensis has been recorded interbreeding with superciliosus in Ishikawa, Japan [15] while superciliosus has interbred with Lanius tigrinus in central Japan. [16]

The nominate form breeds in northern Asia from Mongolia to Siberia and winters in South Asia, Myanmar and the Malay Peninsula. The race confusus described from the same region is not well marked but is said to have a wider white brow and paler upperparts and is sometimes included within the nominate population. Subspecies superciliosus (sometimes called the Japanese shrike) breeds on the islands of Sakhalin, Kuril and Japan and winters in Hainan, Sumatra, Java, and the Sundas. Subspecies lucionensis, sometimes known as the Philippine shrike (local names: tarat or pakis-kis), [17] [18] [19] breeds in Korea and eastern China wintering mainly in Taiwan and the Philippines but also on the Andaman Islands and in peninsular India. [10] [20] [21] [22] Stuart Baker suggested that the species may breed in the Cachar Hills of Assam but the idea was questioned by Claud Buchanan Ticehurst. [23]

This species is rare in Europe and vagrants have been recorded in the United States and Canada. [24] [25] [26]

The brown shrike is a migratory species and ringing studies show that they have high fidelity to their wintering sites, often returning to the same locations each winter. [27] [28] [29] They begin establishing wintering territories shortly after arrival and their loud chattering or rattling calls are distinctive. Birds that arrive early and establish territories appear to have an advantage over those that arrive later in the winter areas. [30] [31] The timing of their migration is very regular with their arrival in winter to India in August and September and departure in April. [32] During their winter period, they go through a premigratory moult. [27] Their song in the winter quarters is faint and somewhat resembles the call of the rosy starling and often includes mimicry of other birds. The beak remains closed when singing and only throat pulsations are visible although the bird moves its tail up and down while singing. [11] [33]

The breeding season is late May or June and the breeding habitat includes the taiga, forest to semi-desert where they build a nest in a tree or bush, laying two to six eggs. [34]

They feed mainly on insects, especially Lepidoptera. [35] Like other shrikes, they impale prey on thorns. Small birds and lizards are also sometimes preyed upon. [36] A white-eye ( Zosterops ) has been recorded in its larder. [11] They typically look out for prey from a perch and fly down towards the ground to capture them. [37]

It has also established itself in parts of Samoa, Australia, USA and Cook Islands. It is included in the list of the world's 100 worst invasive alien species.

Indian robin Species of bird

The Indian robin is a species of bird in the family Muscicapidae. It is widespread in the Indian subcontinent and ranges across Bangladesh, Bhutan, India, Nepal, Pakistan and Sri Lanka. The males of the northern subspecies have brown backs whose extent gradually reduces southwards, with the males of the southern subspecies having all-black backs. They are commonly found in open scrub areas and often seen running along the ground or perching on low thorny shrubs and rocks. The long tail is usually held up and the chestnut undertail coverts and dark body make them easily distinguishable from pied bushchats and Oriental magpie-robins.

Oriental magpie-robin Species of bird

The Oriental magpie-robin is a small passerine bird that was formerly classed as a member of the thrush family Turdidae, but now considered an Old World flycatcher. They are distinctive black and white birds with a long tail that is held upright as they forage on the ground or perch conspicuously. Occurring across most of the Indian subcontinent and parts of Southeast Asia, they are common birds in urban gardens as well as forests. They are particularly well known for their songs and were once popular as cagebirds.

The races in the Indian region are migratory, wintering in the south of the Peninsula and Sri Lanka. The black bazas have short, stout legs and feet with strong talons. A prominent crest is a feature of the bazas. They are found in dense forest often in small groups. They are also known to spend a lot of time perching on bare branches of tall trees rising above the forest canopy.

Baya weaver Species of bird found in southeast Asia

The baya weaver is a weaverbird found across the Indian Subcontinent and Southeast Asia. Flocks of these birds are found in grasslands, cultivated areas, scrub and secondary growth and they are best known for their hanging retort shaped nests woven from leaves. These nest colonies are usually found on thorny trees or palm fronds and the nests are often built near water or hanging over water where predators cannot reach easily. They are widespread and common within their range but are prone to local, seasonal movements mainly in response to rain and food availability.

Ashy minivet Species of bird

The ashy minivet is a passerine bird of eastern Asia belonging to the minivet genus Pericrocotus in the cuckooshrike family Campephagidae. While most of the minivets have shades of yellow, orange and red in their plumage, this species has only greys, whites and blacks. The male is distinctive with a white face and black nape although females can be confused with the female of the brown-rumped minivet. They forage in the canopy, often along with other minivets and join mixed-species foraging flocks.
