Rook
Corvus frugilegusAlso known as Bare-faced Crow
Rooks are highly social corvids easily recognized by the bare, chalky-white skin around the base of their powerful grey bills. They gather in noisy treetop colonies called rookeries, where dozens of pairs build bulky twig nests and maintain complex social hierarchies. On the ground, they walk with a characteristic swagger, probing pastures and agricultural fields for soil-dwelling grubs and fallen grain.

LC
Safe to observe from a distance; nesting adults may defend fallen chicks.
- Listen for rookeries: Locate their noisy treetop colonies in early spring by listening for harsh, repeated cawing.
- Watch foraging behavior: Observe them probing pastures with their strong, pale bills to extract soil invertebrates.
- Keep your distance: Avoid lingering directly beneath active rookeries to prevent disturbance and avoid droppings.
