The yellow-billed shrike (Corvinella corvina) is a large passerine bird in the shrike family. It is sometimes known as the long-tailed shrike, but this invites confusion with the long-tailed shrike, Lanius schach, of tropical southern Asia. It is the only species placed in the genus Corvinella. The yellow-billed shrike is a common resident breeding bird in tropical Africa from Senegal eastwards to Uganda and locally in westernmost Kenya. It frequents forest and other habitats with trees.
The yellow-billed shrike was formally described in 1809 as Lanius corvinus by the English naturalist George Shaw. The specific epithet is from Latin meaning "raven-like". Shaw based his account on "La Grande-pie-grieche" that had been described and illustrated in 1799 by the French naturalist François Levaillant. Levaillant had acquired a preserved specimen from a dealer and did not know its origin. In 1831 the French naturalist René Lesson introduced the genus Corvinella to accommodate the yellow-billed shrike and also designated the type location as Senegal. Based on the results of molecular genetic studies, this species has sometimes been placed in the genus Lanius, but the phylogenetic... Wikipedia →

Possible
About 30% of wildlife watchers report a Yellow-billed Shrike sighting in Serrekunda on a given day, based on 242 verified sightings from GBIF citizen-science data. It is the 50th most-seen of the 213 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
February
In that month about 40% of wildlife watchers report a Yellow-billed Shrike in Serrekunda on a given day, against about 10% in May–June and August–September, the lowest months. That is one of Serrekunda's driest months, with almost no rain against 290 mm in August.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Yellow-billed 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.
4th of 6
Of the 6 cities where we can rate Yellow-billed Shrike sightings, Serrekunda ranks 4th at about 30%. The best odds are in Accra (Ghana, about 50%), Ouagadougou (Burkina Faso, about 50%) and Abuja (Nigeria, about 50%).
GBIF citizen-science records
It is estimated from how often the Yellow-billed Shrike is recorded against all the birds logged in Serrekunda (242 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.
