How do you tell the difference between male and female rooks?
They differ from crows by a bare patch of skin around their bills. Rooks have pointed bills that curve downwards slightly. Due to the lack of nostril bristles, their nostrils are visible. Adult male and female rooks look similar while juveniles are duller with a fully feathered face.
Where do rooks sleep at night?

Where do rooks go during the day?
After a day foraging in the fields, rooks head to the trees en masse; a noisy congregation settling down for a good night’s sleep among the branches. Rooks are communal breeders, nesting in colonies.
What kind of food does a rook eat?
Rooks eat acorns, nuts, cereal grain, leatherjackets, slugs, snails, worms, ants, caterpillars, beetles, crane flies, larvae from crane flies, small animals and even dead animals (carrion). Sometimes Rooks visit gardens to take scraps of food from garden tables. Rooks secretly watch other birds storing their food.
When does the female rook leave the nest?
For the 16 to 18 day incubation period the female rook covers the eggs unless she has to briefly leave the nest, in which case the male takes over this duty. After hatching, the female tends to the young exclusively while the male delivers food.
When is the mating season for a rook?
The mating season for Rooks is around March time. Before the male and the female Rook mate, the male likes to perform a courtship ritual for the female. He fluffs out his feathers and struts proudly around her. Then he caws to her while he bobs his head and body up and down.
How old do Rooks have to be to lay eggs?
Rooks generally take mates when they are two years old. During the fall mating season, pair bonds nest together in communal roosts called rookeries until they return to individual nests to lay eggs. Despite hundreds of birds in a single rookery, rooks maintain their pair bonds through extensive communication.
