Scientific name: Corvus frugilegus
Size: Around 45cm. Wingspan 80cm to 98cm
Distribution: Found throughout the UK.
Months seen: All year round
Habitat: Farmland, grassland and parks. Usually seen in large flocks (often with jackdaws)
Food: Omnivorous - worms, insects, seeds etc.
Special features: Rooks have all black plumage, similar to the carrion crow but the adults have off white coloured cheeks, a grey beak and shaggier plumage (especially around the legs). The plumage has a purple sheen. The juvenile rooks lack the white cheeks for the first year, which makes them look similar to Carrion Crows, but with feathered legs and a purple sheen to the plumage.
Rooks tend to partner for life and mating can occur from late January through to March.
