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 blue rock thrush was described by Carl Linnaeus in 1758 in the 10th edition of his Systema Naturae under the binomial name Turdus solitarius. The type locality is Italy. The scientific name is from Latin. Monticola is from mons, montis "mountain", and colere, "to dwell", and the specific epithet solitarius means "solitary".
The rock thrush genus Monticola was formerly placed in the family Turdidae 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.

Possible
About 20% of wildlife watchers report a Blue Rock-Thrush sighting in Algiers on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 16th most-seen of the 49 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
May, September and December–February
In those months about 30% of wildlife watchers report a Blue Rock-Thrush in Algiers on a given day, against under 5% in June, August and October–November, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Blue Rock-Thrush sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 45
Of the 45 cities where we can rate Blue Rock-Thrush sightings, Algiers ranks 3rd at about 20%. The best odds are in Naha (Japan, about 50%) and Busan (South Korea, about 20%).
Same family: Muscicapidae
The closest relatives of the Blue Rock-Thrush that you can see in Algiers (family Muscicapidae, Old World Flycatchers, Robins, and Chats) are European Robin (about 30%), Spotted Flycatcher (about 10%) and Black Redstart (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Blue Rock-Thrush is recorded against all the birds logged in Algiers (12 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
