Biology:Garrulus

From HandWiki

Garrulus is a genus of Old World jays, passerine birds in the family Corvidae.

Taxonomy and systematics

The genus was established by French zoologist Mathurin Jacques Brisson in 1760.[1] The type species is the Eurasian jay (Garrulus glandarius).[2][3] The name Garrulus is a Latin word meaning chattering, babbling or noisy.[4]

Species

Three species are currently accepted,[5] though some authors split Eurasian jay into three species, thereby accepting five species in the genus.[6]
