Thrushes

 

 

Blackbird singing in the dead of night,
Take these broken wings and learn to fly.
All your life
You were only waiting for this moment to arise.

 

Blackbird singing in the dead of night,
Take these sunken eyes and learn to see.
All your life
You were only waiting for this moment to be free.

 

Blackbird fly, blackbird fly
Into the light of a dark black night.

 

John Lennon/Paul McCartney, 1968

From childhood, I have been fond of thrushes. I was deeply fascinated by the blackbird, which, cocking its head, was listening for movements beneath our lawn, and would then suddenly sink its bill into the ground and pull forth a wriggling earthworm. And in the summertime, before dawn, our neighborhood would echo with the melodious song from a chorus of males, performed from tree tops, flagpoles, or rooftops. On family picnic trips to the woods, we could enjoy the more staccato-like song of the blackbird’s smaller cousin, the song thrush, which constantly changed its theme and would variate the song indefinitely.

Later, when I had developed a deeper interest in birds, I realized that other species of thrushes could be encountered in Denmark. In the coniferous plantations of Jutland, you might get a glimpse of the mistle thrush, which resembled a large song thrush, but could be identified by its white underwing and the hissing call, reminiscent of a wren’s call. In spring, you might be lucky enough to observe a small flock of ring ouzels, feeding in a field before continuing their northbound migration. And one of the positive signs of autumn were large flocks of fieldfares and redwings, zooming across windblown fields, or tucking into the abundant supplies of rosehips, haws, elder berries, or fallen apples.

When I began travelling, I encountered many other species of thrushes. The family Turdidae is still large, although numerous smaller species, following a number of genetic studies, have now been transferred to other families. The genus Turdus, to which our European thrushes belong, is by far the largest genus, comprising about 84 species, and otherwise the family presently encompasses 17 other genera, counting altogether about 80 species.

The word thrush is derived from Old English throstle, from Proto-Germanic þrustlō, an ancient name for the song thrush. In Old Saxon, þrustlō became throsla, in German Drossel. The latter name was adopted by the Danes, whereas the Swedes use the name trast for these birds, and the Norwegians trost.

Below, a number of species of the thrush family, which I have managed to photograph around the world, are presented.

 

 

Genus Turdus

 

Blackbird (Turdus merula)
The black plumage of the male blackbird has given rise to its name. The Proto-Germanic name for this bird was amslo, which in German became Amsel, and in Old English osle, which was later changed to wosel, wozel, or ouzel, the latter used until about the 17th Century. Incidentally, ouzel is still used in the name ring ouzel (see further down on this page).

In A Midsummer Night’s Dream, by William Shakespeare (1564-1616), the weaver Nick Bottom sings:

 

The woosell cocke, so blacke of hew,
With orenge-tawny bill,
The throstle, with his note so true,
The wren and little quill.

 

During the last hundred years or so, the blackbird has spread to virtually all urban areas in Europe, and today it is one of the most common city birds. From being a shy forest bird, it has changed to become very confiding indeed, sometimes breeding in garages and tool sheds, where the incubating female will not leave the nest, even if the owner is doing his business close to it.

This species is distributed from Iceland and northern Scandinavia southwards to Morocco, Egypt, and Jordan, and thence eastwards across northern Iraq and Iran to eastern Kazakhstan and Kyrgyzstan. In Russia, it is restricted to the westernmost part. Central Asian birds, which were formerly considered to be a subspecies of the blackbird, are now generally regarded as a subspecies of Turdus maxima.

The blackbird was introduced to Australia in 1857 and to New Zealand in 1862. Today, it is one of the commonest birds in New Zealand.

Song thrush (Turdus philomelos)
As explained above, the ancient Proto-Germanic name of the song thrush, þrustlō, has given name to the entire group. The specific name is derived from the Greek philein (‘to love’) and melos (‘melody’), alluding to the fantastic song of this bird.

The song thrush has a wide distribution, breeding from northern Norway southwards to northern Spain, Italy, northern Greece, northern Turkey, and northern Iran, and from Ireland eastwards through Europe and Siberia, almost to Lake Baikal. Northern and eastern populations are migratory, spending the winter in southern Europe, northern and north-eastern Africa, and the Middle East. It was introduced to New Zealand in 1862, and today it is very common here. It is also found in a relatively small area of south-eastern Australia.

Fieldfare (Turdus pilaris)
The fieldfare is a large thrush, which breeds in scrubland and open forests, from northern Norway southwards to France, Switzerland, northern Italy, northern Slovenia, and northern Ukraine, and from eastern France eastwards across the entire taiga zone to eastern Siberia, Mongolia, and northern China. In England, it is a scarce breeding bird. Populations of Scandinavia and Siberia are migratory, spending the winter in the British Isles, southern Europe, northern Africa, the Middle East, and areas around the Caspian Sea.

The name fieldfare is derived from the 11th Century word feldefare, which, according to some authorities, means ‘traveller across the fields’. However, in a paper from 1855, On False Etymologies, in Transactions of the Philological Society (6): 69, H. Wedgwood points out that this is a false presumption. In reality, the name is derived from the old Anglo-Saxon name of the bird, feala-for, perhaps alluding to the tawny-yellow colour on the breast.

Redwing (Turdus iliacus)
The redwing is a small thrush, whose name stems from its red underwing and flanks. It breeds in northern Europe and Asia in open forests and montane shrubs of birch and willow, from Iceland and northern Scotland eastwards through the entire Scandinavian Peninsula, Finland, and Russia to eastern Siberia. It is also found in the Baltic States, eastern Poland, Belarus, and northern Ukraine, and in Central Asia, it breeds as far south as northern Kazakhstan and northern Mongolia. It breeds sporadically in Denmark, and since 1990, a small population has also been breeding in southern Greenland.

This species is migratory, spending the winter in western Europe, and around the Mediterranean, the Black Sea, and the Caspian Sea. Some birds in south-western Norway and Scotland are resident.

Ring ouzel (Turdus torquatus)
The ring ouzel is similar to a blackbird, but is slightly smaller and slimmer, and it may at once be identified by its striking white breast band, which is the cause of the first part of its name. (The name ouzel is explained under blackbird.) It also has a pale wing panel. Male and female are quite similar, but the female is greyer and has scaly markings on the underside.

Three subspecies of this bird are distributed across Europe and western Asia, breeding in all of Norway, the extreme western part of Sweden, the northern tip of Finland, on the Kola Peninsula, and in the Timan Mountains, near Arkhangelsk, and also in Scotland, northern England, Wales, and Ireland, in the Pyrenees, the Alps, and mountains of eastern Europe and the Balkans, in southern and eastern Turkey, in the Caucasus, and in northern Iran. In the major part of its distribution area, it is restricted to mountains, where it nests in gullies, rocky areas, or among scree. However, in Scandinavia and the British Isles it may be found down to sea level.

The species is migratory, spending the winter in southern Spain, North Africa, the Balkans, southern Turkey, and western Iran.

Indian blackbird (Turdus simillimus)
Four subspecies of this bird are distributed in montane areas of the southern half of the Indian Peninsula and in Sri Lanka. Formerly, they were regarded as subspecies of the common blackbird, but they are rather smaller, only c. 20 cm versus c. 25 cm, the naked skin around the eye is broader, and egg colour and voice also differ from the common blackbird. It has been concluded that the similarity between these two species is an example of convergent evolution.

Brown-headed thrush (Turdus chrysolaus)
The brown-headed thrush is endemic to East Asia, breeding from Sakhalin and the Kuril Islands southwards to central Honshu, Japan, spending the winter in southern Japan, Taiwan, and the Philippines. This bird is mainly of a warm brown colour, with reddish breast and white central belly. The male has blackish-brown head and throat, whereas the female has whitish throat with black vertical stripes.

African thrush (Turdus pelios)
About nine subspecies of the African thrush are distributed in sub-Saharan Africa, from Senegal eastwards to South Sudan and Ethiopia, southwards to northern Angola and northern Zambia.

Previously, seven of these subspecies were included in the olive thrush (Turdus olivaceus), which was described in 1760 by French naturalist Mathurin Jacques Brisson (1723-1806) in his Ornithologie, ou, Méthode contenant la division des oiseaux en ordres, sections, genres, especes & leurs variétés, based on a specimen collected from Cape of Good Hope, South Africa. He applied a French name to it, Le merle olive du Cap de Bonne Espérance, and also a Latin name, Merula Olivacea Capitis Bonae Spei.

In 1766, when the well-known Swedish naturalist Carolus Linnaeus (1707-1778), also called Carl von Linné, updated his Systema Naturæ for the 12th edition, he added 240 species, which Brisson had previously described, including the olive thrush, naming it Turdus olivaceus, and citing Brisson’s work. (Source: Allen, J.A. 1910. Collation of Brisson’s genera of birds with those of Linnaeus. Bulletin of the American Museum of Natural History, 28: 317-335)

There is still some controversy about the relationship between these two species, and some authorities maintain that some of the subspecies of African thrush should be transferred back to the olive thrush, which, as of today, is restricted to southern Africa.

Kurrichane thrush (Turdus libonyana)
This species is found from Angola, north-eastern Namibia, and south-eastern Zaire to the east coast of Africa, and from south-eastern Burundi and northern Tanzania southwards to south-eastern South Africa, where it lives in dry savanna and open woodland. It resembles the African thrush, but has a whitish throat with a black malar stripe on each side.

The specific name was given by mistake to this species. It is derived from lebonyana, the Tswana name for the red-billed buffalo-weaver (Bubalornis niger). The prefix Kurrichane is a corruption of the name Kaditshwene, a place in South Africa, where the original specimen was collected. That name is thought to be derived from a Tswana expression: “Ga se ka ditshwene!”, meaning “What an incredible number of baboons!” (Source: J. Boeyens 2000. In Search of Kaditshwene. The South African Archaeological Bulletin, 55 (171): 3-17)

American robin (Turdus migratorius)
As a breeding bird, the American robin has a very wide distribution indeed, from northern Alaska and Canada southwards through the entire United States (except Florida), to north-western Mexico and Baja California. Northern populations are migratory, wintering from the southernmost parts of Alaska and Canada southwards to southern Mexico and Guatemala. It is one of the commonest land birds of North America, and is the state bird of Connecticut, Michigan, and Wisconsin.

The American robin is regarded as a symbol of spring. The poem The First Robin, by Canadian poet William Henry Drummond (1854-1907), is based on a Quebec superstition that whoever sees the first robin of spring will have good luck.

This bird was named robin by early settlers, as its reddish-orange breast reminded them of the European robin (Erithacus rubecula).

Genus Geokichla
In 2008, following genetic studies, a group of thrushes, encompassing c. 21 species, which were traditionally placed in the genus Zoothera, were moved to the genus Geokichla. This genus was established in 1836 by German naturalist Salomon Müller (1804-1864), who explored parts of Dutch East Indies (today Indonesia) between 1826 and 1835. The generic name is from the Greek geo (‘ground’) and kikhle (‘thrush’), referring to the almost exclusively ground-feeding habit of these birds.

 

Orange-headed ground-thrush (Geokichla citrina)
Eleven subspecies of this pretty bird breed along the entire Himalayan Range, in eastern and Southern India, on the Andaman and Nicobar Islands, in Indochina, southern and eastern China, and northern Borneo, and on Java and Bali. It is resident in the major part of this huge area, but some northern populations are migratory, spending the winter in north-eastern and southern India, Sri Lanka, Sumatra, and southern China.

Subspecies cyanota of southern India is very distinct, having a white face with two vertical black streaks below and behind the eye. It has been suggested that it forms a separate species, but intermediate forms occur where its range overlaps with that of nominate citrina.

Spotted ground-thrush (Geokichla guttata)
The spotted ground-thrush, which was previously named Zoothera guttata, is a scarce bird with a very fragmented distribution, found in a few forest areas in South Sudan, Zaire, Kenya, Tanzania, Malawi, South Africa, and possibly Mozambique. This species, which is severely threatened by loss of suitable habitat, spends much time searching for small invertebrates among the leaf-litter on the forest floor. Its distinctive colouration is an adaptation that makes it difficult to see among the leaves.

Genus Psophocichla
This is a small genus of one or two species, depending on authority. Here, I follow Handbook of the Birds of the World, which proposes two species. The generic name is from the Greek psóphos (‘loud noise’) and kikhle (‘thrush’), referring to the loud, clicking call of these birds.

 

Groundscraper thrush (Psophocichla litsitsirupa)
A most striking bird, easily identified by its upright stance, streaked breast, and two black vertical stripes below and behind the eye, similar to those of subspecies cyanota of the orange-headed ground-thrush (see above).

This species occurs in grasslands and open woodland, from northern Angola eastwards to western Tanzania, Malawi, and north-western Mozambique, southwards to Namibia and north-eastern South Africa.

The specific name litsitsirupa is a Tswana word, imitating the bird’s call.

Ethiopian thrush (Psophocichla simensis)
This bird, which is restricted to the highlands of Ethiopia and Eritrea, was formerly regarded as being conspecific with the groundscraper thrush. However, besides being geographically isolated, its black facial markings are much weaker, the spots on the underparts are fewer and rounder in shape, and the back is more brownish. (Source: Handbook of the Birds of the World).

Genus Grandala
This genus contains only one species, described in Nepal in 1843 by British naturalist and ethnologist Brian Houghton Hodgson (1801-1894), who found numerous species of birds and mammals, new to science, in the Himalaya.

Classification-wise, this species has been knocked about a great deal. Initially, it was regarded as belonging to the thrush family, but following some genetic studies it was then transferred to the flycatcher family (Muscicapidae). However, recently it has been moved back to the thrush family!

 

Grandala (Grandala coelicolor)
The male grandala is a gorgeous bird, whose plumage is an almost iridescent hue of blue, whereas the female is greyish with faint white stripes on head, nape, and breast, and a brownish tinge to the wings. This species is distributed from Kashmir along the entire Himalayan chain, and thence northwards through eastern Tibet to western China, from northern Yunnan northwards to eastern Qinghai. It breeds at very high altitudes, between 4,000 and 5,500 m, moving to slightly lower elevations in winter.

Genus Sialia
Bluebirds comprise one of the few genera of the thrush family, which is endemic to the Americas, containing three species, which are distributed from southern Canada southwards to Nicaragua. As their name implies, they have blue plumage, two of the species also with red parts on the underside.

 

Western bluebird (Sialia mexicana)
Initially, this bird was confined to open hardwood forests in grasslands, but has lost a lot of its habitat due to cultivation and logging. However, it has been able to adapt to other habitats, including coniferous forest, farmland, and desert, and is still quite common.

This species is distributed in two geographically separate areas, from British Columbia, Washington, and Montana southwards through Oregon, California, and western Nevada to northern Baja California, and from Utah and Colorado southwards to the Mexican states of Oaxaca and Veracruz. Northern populations are migratory, spending the winter in south-western U.S. and northern Mexico.

Genus Neocossyphus
Ant-thrushes are two species of medium-sized insectivorous birds, living in forests of sub-Saharan Africa.

 

Red-tailed ant-thrush (Neocossyphus rufus)
This species is found in two geographically separate areas, from southern Cameroun and Gabon eastwards across northern Zaire to western Uganda, and in coastal forests of Kenya and Tanzania, including Zanzibar.
