The rook (Corvus frugilegus) is a member of the family Corvidae in the passerine order of birds.  This species is similar in size 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 feathering around the legs also looks shaggier and laxer than the congeneric carrion crow.

Crow with coloured plastic ring in Jardin des Plantes, Paris. To better answer to stakeholders asking how to face disturbances caused by the numerous crows living in Paris city, a research study started in July 2015 under the lead of Frédéric Jiguet, professor at the National Museum of Natural History, following a request by the Paris environment services. Five years later, more than 550 crows have been captured and ringed with coloured plastic rings engraved with a three-digit code, so that people visiting the city can relocate them. Many individuals spend the day in Tuileries but\nmove in late afternoon to join a roost in Jardin\ndes Plantes, which has numerous tall trees.
