Meridiocichla salotti was a large extinct thrush from the Late Quaternary of the Mediterranean. Antoine Louchart named the genus and species in 2004 from fossil material associated with Corsica and Crete. Its bones are chiefly scattered elements of the limbs and shoulder region, enough to compare proportions and place it among thrushes, but not to recover its full appearance or daily behaviour. The word “southern” in the genus name does not point to South America: the documented fossils are Mediterranean. The extinct bird catalogue includes Meridiocichla as an island passerine known mostly from skeletal evidence.

What can the fossils tell us?
The genus was diagnosed from comparison with living turdids, using proportions and joint and muscle-attachment features. Fragmentary remains do not preserve every part of the skeleton.
Material from Corsica and Crete supports occurrence on both islands. Other proposed mainland finds are unconfirmed and cannot be added as secure records.
Limb bones support a large-bodied bird comparable in scale to a large modern thrush. They do not establish one exact mass or explain why its size evolved.
The skull and gut contents are insufficient to define a menu, and available dates do not identify one extinction event or cause.
Naming a Mediterranean thrush
Antoine Louchart described Meridiocichla salotti in 2004 as a new genus and species of thrush from the Late Quaternary of Mediterranean Europe. The name can be rendered as “southern thrush,” but the animal is not a South American bird. Secure fossils are reported from Corsica and Crete. The old Russian headline that called it South American is geographically incorrect; the published record places it on Mediterranean islands.
The diagnosis rests on a combination of skeletal features compared with living thrushes, not on one unusually large bone alone. The known material consists mainly of disarticulated bones from the legs and shoulder girdle. These elements help establish proportions and systematic affinity, while a complete skull and articulated skeleton are not available to show every diagnostic feature in one individual.
Because the fossils are fragmentary, taxonomic identification depends on careful comparison across collections. A large passerine leg bone may resemble more than one group, and body size can overlap among unrelated birds. The named species is currently treated as the only member of the genus; uncertain isolated remains elsewhere in Europe should not be used to expand its range without a direct anatomical basis.
A large thrush on Corsica and Crete
Meridiocichla is reported from cave and other Quaternary deposits on Corsica and Crete. Most material is Late Pleistocene in age. Some Corsican layers have been assigned a broader interval that could reach the early Holocene, but that does not provide a single secure date for the species’ disappearance. Layer dates can also differ in reliability depending on how fossils and sediments accumulated.
Island caves are complex fossil traps and archives. Bones may collect through predator activity, natural accidents or sediment movement, and separate elements found together need not all belong to one bird. The deposits can reveal which species occurred in a region and preserve comparative anatomy, but they do not automatically preserve nests, flock behaviour or the cause of an individual’s death.
The known island distribution also does not prove the thrush was limited to only two islands. Fossilisation is uneven, and unconfirmed reports from mainland France, Italy or Mallorca remain less secure than the material used to describe the genus. A fossil range is therefore a map of reliable finds, not a complete census of the living population.
What the bones say about its body
The bones indicate a bird larger than most modern European thrushes. Louchart compared it in general scale with the Asian scaly thrush, Zoothera dauma. This is a size comparison, not a claim that the fossil species looked exactly like that living bird or had the same ecology. No intact body gives a precise mass, and one reconstructed value would hide uncertainty in the proportions.
The available wing and leg elements do not show that Meridiocichla had lost flight. They support a passerine body plan but do not measure flight strength, speed or distance. Island bird communities often evolve unusual body sizes, yet “island gigantism” is only a starting hypothesis here. To explain the large size would require stronger information about food, predators, competitors and the history of each island ecosystem.
The skull is too incomplete to define its diet directly. Living thrushes commonly take fruits and invertebrates, so a broadly mixed menu is plausible by comparison. There are no known stomach contents or other direct feeding traces tied to Meridiocichla. Its size alone cannot tell whether it favoured fruit, ground prey or a particular forest layer.
A distinct island history
The Corsican bird is not the same species as the Mascarene thrush Necropsar, which belonged to a separate island history and lived much later. Similar island settings can produce superficial parallels without indicating close relationship. Family-level placement in Turdidae is based on anatomy, not simply on the fact that both birds were large and insular.
There are no preserved feathers that reveal colour, pattern, sexual differences or a crest. Song, nesting behaviour and seasonal movement are likewise unknown. Illustrations can show the general shape of a large thrush, but plumage details necessarily borrow from living relatives. Even a plausible image should not be mistaken for a recovered appearance.
Its extinction is also unresolved. Late Pleistocene climate change altered vegetation and habitat on Mediterranean islands; human settlement and introduced animals may have added further pressures. No direct evidence currently isolates one of these as the cause for Meridiocichla, and the available dates do not establish an exact final population. The strongest conclusion is narrower: a large thrush lived on at least two islands during the Late Quaternary, and its fossil record is too sparse to reconstruct the final stages of its history.
Frequently asked questions
Where did Meridiocichla live?
Secure fossils are known from Corsica and Crete in the Mediterranean. Proposed remains elsewhere are not as firmly identified.
Was it a South American bird?
No. Its documented fossils come from Mediterranean islands; the word “southern” in the name does not indicate South America.
How large was it?
It was larger than most living European thrushes and has been compared in scale with a large Zoothera. An exact mass is not established.
What caused its extinction?
The dates are too limited to identify one cause. Climate change, human activity and introduced animals are possible pressures, not proven explanations.
