Julian and Eileen
We may ask the reverse question, if one is to start by a
kingfisher-inspiration would the results lead to a nose cone similar to
that implemented?? regardless of the truth of that myth or not. If it is
true, and I do not know for sure, then that is a case for bio-inspiration.


There are cases in aerodynamics when some wing structures were thought by
aerodynamicists (e.g, swept back wing-tips and crescent shaped wings)
independent from a biological-inspiration. It was discovered later on, that
some of the shapes are the cause of efficient flight in some bird species.
