Secretary Birds' were named because the quill-like feathers on its head were reminiscent of those once used for writing. It is unusual to catch one coming to water. [Hwange NP, Zimbabwe].
It is unusual to see three Secretary Birds together. I think that it is a pair with their subadult chick. [Hwange NP, Zimbabwe].

Triple image: Three views of the same Secretarybird that I found hunting in Botswana. The quills on the back of its head are well demonstrated. Because it appeared to be hunting alone---they usually hunt in pairs---I assume that it was calling to summon its mate (1st & 3rd images). [Botswana].
