Elusive - II (did I say elusive??)

I find this bird, in general, almost impossible to photograph with any degree of poise (either on its' or mine own part) although occasionally it will completely ignore me and I go wild snapping a dozen almost identical photographs of it drilling its' big square feeding hole in dead wood - but today it, or rather them as there were two flying what I would imagine to be a courtship whirling flight,  hiding in thickets of leaves or behind trunks of trees and then coyly taking flight again
