+ Corvidae, Description
  * Crows are some of the most intelligent birds in the world. Crows and rooks are good at using tools, for example sticks or twigs. Magpies can see themselves in a mirror and they understand that it is a reflection. Many crows live near to humans in towns and cities. They are more shy than the crows that live in cities.
  * Some crows in North America, Europe and northern Asia migrate. This means they travel to different places in summer or winter. Most crows are resident birds. This means they live in the same place all year round.
  * Crows eat a variety of food. Because they may attack the nest of other birds, crows may get mobbed by other species. This is when the defending birds group together to chase off the crow. Also, on farms, crows will eat vegetables and seeds. Farmers do not want this to happen so they make a scarecrow. This is a object made of straw and old clothes.
  * Crows make their nests in tall trees. They make the nest from large sticks. Both parents will look after the fledglings.
