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.

Rare
Under 5% of wildlife watchers report a Blue Rock-Thrush sighting in Hong Kong on a given day, based on 50 verified sightings from GBIF citizen-science data. It is the 123rd most-seen of the 204 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
October
In that month about 10% of wildlife watchers report a Blue Rock-Thrush in Hong Kong on a given day, against under 5% in November to September, the lowest months. That is one of Hong Kong's driest months, with about 50 mm of rain against 280 mm in June.
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.
27th of 45
Of the 45 cities where we can rate Blue Rock-Thrush sightings, Hong Kong ranks 27th at under 5%. The best odds are in Naha (Japan, about 50%), Busan (South Korea, about 20%) and Algiers (Algeria, about 20%).
Same family: Muscicapidae
The closest relatives of the Blue Rock-Thrush that you can see in Hong Kong (family Muscicapidae, Old World Flycatchers, Robins, and Chats) are Oriental Magpie-Robin (about 80%), Blue Whistling-Thrush (about 30%) and Asian Brown Flycatcher (about 20%), 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 Hong Kong (50 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.
