Buzzard calls

[FredPuli43]

'Our' buzzards here, a pair which have nested somewhere nearby, are the noisiest birds. They call when they are alone, they call when they are together, and they call in flight, although the calls differ at each time. I just wondered how they ever catch anything ! Any prey must hear them a long way off. Is it that they go silent when actually hunting, or that they are helped by the call in causing prey to move and so becoming more easily visible or caught, or that the prey is not able to escape whether they make a noise or not?

From what I know about Buzzards, their call doesn`t make any difference to their prey. If they are a pair, they will be calling to their offspring. Usually, it is the fledgeling that calls to the parents and they make a very distinctive sound. Buzzards have a very large territory and calling is the only way that they can communicate there whereabouts to their offspring.
