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 genus name, Lanius, is derived from the Latin word for "butcher", and some shrikes are also known as "butcher birds" because of their feeding habits. 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 →

Likely
About 60% of wildlife watchers report a Brown Shrike sighting in Manila on a given day, based on 2,620 verified sightings from GBIF citizen-science data. It is the 7th most-seen of the 191 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
October
In that month about 90% of wildlife watchers report a Brown Shrike in Manila on a given day, against under 5% in June, the lowest month. That is one of Manila's wettest months, with about 340 mm of rain against 100 mm in April.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Brown Shrike sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 80 cities where we can rate Brown Shrike sightings, Manila has the highest daily chance: about 60%. Next come Kaohsiung (Taiwan, about 50%) and Davao City (Philippines, about 50%).
GBIF citizen-science records
It is estimated from how often the Brown Shrike is recorded against all the birds logged in Manila (2,620 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.
