The brown shrike (Lanius cristatus) is a bird in the shrike family that is found mainly in Asia. It is closely related to the red-backed shrike (L. collurio) and isabelline shrike (L. isabellinus).

The specific cristatus is Latin for "crested", used in a broader sense than in English. The common English name "shrike" is from Old English scríc, "shriek", referring to the shrill call.
Like most other shrikes, it has a distinctive black "bandit-mask" through the eye and is found mainly in open scrub habitats, where it perches on the tops of thorny bushes in search of prey. Several populations of this widespread species form distinctive subspecies which breed in temperate Asia and migrate to their winter quarters in tropical Asia. They are sometimes found as vagrants in Europe and North America.
In 1747 the English naturalist George Edwards included an illustration and a description of the brown shrike in the second volume of his A Natural History of Uncommon Birds. He used the English name "The Crested Red, or Russit Butcher... Wikipedia →

With luck
About 10% of wildlife watchers report a Brown Shrike sighting in Tiruchirappalli on a given day, based on 19 verified sightings from GBIF citizen-science data. It is the 65th most-seen of the 90 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Brown Shrike is recorded against all the birds logged in Tiruchirappalli (19 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.
