Rook Corvus frugilegus
The Rook can be distinguished from the Carrion Crow by its large, light grey beak and barer face; it is also not
as sleek, often with shaggy feathers on its belly giving it an angular shape.
Typical bare grey beak and shaggy, angular shape.
It is gregarious, found in flocks and roosting in rookeries of many nests in neighbouring trees.
It is native to much of temperate Eurasia.
Its corvid relative the Jay is well known for burying acorns for winter (and propagating oak trees).
Here a Rook is doing the same, collecting acorns from beneath a tree and burying them in a field.
