Rooks are fascinating members of the crow family ✔️ 1. Rooks are highly social birds and are often seen in large flocks. ✔️ 2. Rooks build large nests made of twigs and branches, often located in tall trees. These nests can be communal, housing multiple individuals. ✔️ 3. A rook’s call is usually described as kaah; it is similar to that of the carrion crow, but with a somewhat flatter tone. 🎶 Listen to the Rooks sing | RIO Friends Club
