Turdus solitariusLinnaeus, 1758

The blue rock thrush (Monticola solitarius) is a species of chat. This thrush-like Old World flycatcher was formerly placed in the family Turdidae. It breeds in southern Europe, northwest Africa, and from Central Asia to northern China and Malaysia. The blue rock thrush is the official national bird of Malta (the word for it in Maltese being Merill) and was shown on the Lm 1 coins that were part of the country's former currency.

Taxonomy

The blue rock thrush was described by Carl Linnaeus in 1758 in the 10th edition of his Systema Naturae under the binomial name Turdus solitarius. [2] [3] The scientific name is from Latin. Monticola is from mons, montis "mountain", and colere, "to dwell", and the specific epithet solitarius means "solitary". [4]

The rock thrush genus Monticola was formerly placed in the family Turdidae [5] but molecular phylogenetic studies have shown that the species in the genus are more closely related to members of the Old World flycatcher family Muscicapidae. [6]

There are five recognised subspecies: [7] [8]

There is a proposal to split Monticola solitarius into two species: a western taxon comprising M. s. solitarius and M. s. longirostris and an eastern taxon with M. s. philippensis, M. s. pandoo and M. s. madoci. [9]

Description

The blue rock thrush is a starling-sized bird, 21–23 cm (8.3–9.1 in) in length with a long slim bill. The breeding male of the nominate subspecies is unmistakable, with all blue-grey plumage apart from its darker wings. [8] Females and immatures are much less striking, with dark brown upperparts, and paler brown scaly underparts. The male of the subspecies M. s. philippensis has rufous-chestnut plumage from the mid-breast down to the undertail. [8] Both sexes lack the reddish outer tail feathers of rock thrush.

The male blue rock thrush sings a clear, melodious call that is similar to, but louder than, the call of the rock thrush.

Distribution and habitat

The European, north African and southeast Asian birds are mainly resident, apart from altitudinal movements. Other Asian populations are more migratory, wintering in sub-Saharan Africa, India and southeast Asia. This bird is a very uncommon visitor to northern and western Europe. It is known to have been spotted in North America twice: once in British Columbia in 1997 and once in Oregon in 2024. [10] [11]

Behaviour

Blue rock thrush breeds in open mountainous areas. It nests in rock cavities and walls, and usually lays 3-5 eggs. An omnivore, the blue rock thrush eats a wide variety of insects and small reptiles in addition to berries and seeds. [8]

The bluethroat is a small passerine bird that was formerly classed as a member of the thrush family Turdidae, but is now known to be an Old World flycatcher, in the family Muscicapidae. It, and similar small European species, are often called chats.

<span class="mw-page-title-main">Thrush (bird)</span> Family of birds

The thrushes are a passerine bird family, Turdidae, with a worldwide distribution. The family was once much larger before biologists reclassified the former subfamily Saxicolinae, which includes the chats and European robins, as Old World flycatchers. Thrushes are small to medium-sized ground living birds that feed on insects, other invertebrates, and fruit. Some unrelated species around the world have been named after thrushes due to their similarity to birds in this family.

<span class="mw-page-title-main">Wheatear</span> Genus of birds

The wheatears are passerine birds of the genus Oenanthe. They were formerly considered to be members of the thrush family, Turdidae, but are now more commonly placed in the flycatcher family, Muscicapidae. This is an Old World group, but the northern wheatear has established a foothold in eastern Canada and Greenland and in western Canada and Alaska.

<span class="mw-page-title-main">Whinchat</span> Species of bird

The whinchat is a small migratory passerine bird breeding in Europe and western Asia and wintering in central Africa. At one time considered to be in the thrush family, Turdidae, it is now placed in the Old World flycatcher family, Muscicapidae. Both sexes have a strong supercilium, brownish upper parts mottled darker, a pale throat and breast, a pale buff to whitish belly, and a blackish tail with white bases to the outer tail feathers, but in the breeding season, the male has an orange-buff throat and breast.

<span class="mw-page-title-main">European stonechat</span> Species of bird

The European stonechat is a small passerine bird that was formerly classed as a subspecies of the common stonechat. Long considered a member of the thrush family, Turdidae, genetic evidence has placed it and its relatives in the Old World flycatcher family, Muscicapidae. It is found across Europe, as far east as Ukraine and the South Caucasus, and in parts of North Africa.

<span class="mw-page-title-main">Common redstart</span> Species of bird

The common redstart, or often simply redstart, is a small passerine bird in the genus Phoenicurus. Like its relatives, it was formerly classed as a member of the thrush family, (Turdidae), but is now known to be an Old World flycatcher.

<span class="mw-page-title-main">Old World flycatcher</span> Family of birds

The Old World flycatchers are a large family, the Muscicapidae, of small passerine birds restricted to the Old World, with the exception of several vagrants and two species, bluethroat and northern wheatear, found also in North America. These are mainly small arboreal insectivores, many of which, as the name implies, take their prey on the wing. The family is relatively large and includes 357 species, which are divided into 54 genera.

<span class="mw-page-title-main">Rock thrush</span> Genus of birds

<i>Cochoa</i> Genus of birds

The cochoas are medium-sized frugivorous, insectivorous and molluscivorous birds in the genus Cochoa. Their bright contrasting plumage patterns, sexual dimorphism and feeding habits made their systematic position difficult to ascertain in early times, Richard Bowdler Sharpe placed them with the Prionopidae in 1879 while many considered them as some kind of aberrant thrush. The genus was previously included in the Old World flycatcher family Muscicapidae but molecular phylogenetic studies have shown that it is more closely related to the thrush family Turdidae.

<span class="mw-page-title-main">Common rock thrush</span> Species of bird

The common rock thrush, also known as rufous-tailed rock thrush or simply rock thrush, is a chat belonging to the family Muscicapidae. It was formerly placed in the family Turdidae. The scientific name is from Latin. Monticola is from mons, montis "mountain", and colere, "to dwell", and saxatilis means "rock-frequenting", from saxum, "stone".

The forest rock thrush is a songbird in the family Muscicapidae, formerly placed in the Turdidae together with the other chats. It now includes Benson's rock thrush and Amber Mountain rock thrush as subspecies.

<i>Phoenicurus</i> Genus of birds

Phoenicurus is a genus of passerine birds in the Old World flycatcher family Muscicapidae, native to Europe, Asia and Africa. They are named redstarts from their orange-red tails. They are small insectivores, the males mostly brightly coloured in various combinations of red, blue, white, and black, the females light brown with a red tail. A molecular phylogenetic study published in 2010 led to a reorganization of the Old World flycatchers family in which the two species in Rhyacornis and the single species in Chaimarrornis were merged into Phoenicurus.
