Question

3. What sound do the rooks make and why?
4. How long do the rooks work?​

Answer 1

Answer:

1. The call is usually described as caw or kaah, and is somewhat similar to that of the carrion crow, but less raucous. The call is frequently made during flight but is also heard from the tree-tops. No doubt it serves as a contact all, perhaps releasing a build-up of nervous energy. Rooks also make a call rather like that of a jackdaw Corvus monedula, but caution is needed here because of the habits of jackdaws.

2. Other behaviours are used to reinforce the 'pair bond' that exists between a female and her mate, a bond that can last for many years – bird ringing has revealed that a Rook may live for 20 years or more.
