Bobbin' along?

[Mathew simonds]

Just curriosity, why do Falcons 'bob' their head?

[Saker-Clive]

In general hawk and falcons do this when they see something they are interested in............................food or quarry mainly.

[Mathew simonds]

Ah. Just noticed, at the sanctuary i help at, we got an american kesteral, peregrine falcon, saker falcons and a lanner falcon, and I've noticed, with the lanner and kezzy the most, they turn their head, and then 'bob' it.

It is to focus and judge distances.
