One Jackdaw and some Rooks in my hometown park :)

The Western Jackdaw (Corvus monedula), sometimes known as the Eurasian Jackdaw, European Jackdaw or simply Jackdaw, is a passerine bird in the crow family. Found across Europe, western Asia and North Africa, it is mostly resident, although northern and eastern populations migrate south in winter. Measuring 34–39 centimetres (13–15 in) in length, the Western Jackdaw is a black-plumaged bird with a grey nape and distinctive pale-grey irises. It is gregarious and vocal, living in small groups with a complex social structure in farmland, open woodland, on coastal cliffs, and in urban settings. An omnivorous and opportunistic feeder, it eats a wide variety of plant material and invertebrates, as well as food waste from urban areas. Western Jackdaws are monogamous and build simple nests of sticks in cavities in trees, cliffs, or buildings. About five pale blue or blue-green eggs with brown speckles are laid and incubated by the female. The young then fledge in four to five weeks.

The Rook (Corvus frugilegus) is a member of the Corvidae family in the passerine order of birds. This species is similar in size (45–47 cm in length) to or slightly smaller than the Carrion Crow with black feathers often showing a blue or bluish-purple sheen in bright sunlight. The feathers on the head, neck and shoulders are particularly dense and silky. The legs and feet are generally black and the bill grey-black. Rooks are distinguished from similar members of the crow family by the bare grey-white skin around the base of the adult's bill in front of the eyes. The Rook eats predominantly earthworms and insect larvae. It also eats cultivated cereal grain, smaller amounts of fruit, small mammals, acorns, small birds, their eggs and young and carrion. In urban sites, human food scraps are taken from rubbish dumps and streets. Nesting in a rookery is always colonial, usually in the very tops of the trees. Eggs are usually 3–5 in number, can appear by the end of February or early March and are incubated for 16–18 days. Both adults feed the young, which are fledged by the 32nd or 33rd day. In captivity, when confronted with problems, rooks have been documented as one of several species of birds capable of using tools to obtain a goal.
