Thank you, my friends, for your suggestions, all of which have a grain of truth, but not the specific answer in one single word.
Graham: Apasserine was alluding to a bird brained idea which had nothing to do with red herrings which are fish. You are on the right track. I could be described as Apodidae sic legless, following hip replacements too.
Matthew: Nothing to do with cat-fishing. Two Passerines sitting on a Perch. One said to the other, “Can you smell fish”?
John: As always straight to the bottom line, never happier than when we are-singing about in the choir with your bass(sic) instincts.
Graham: Seeking to anchor in another Hamlet. ‘Two bees or not two pees, that is the question? Whether it is nobler in the mind to suffer the slings and arrows of outrageous fortune… ‘. No. Taking Apis would be contrary to the petition to ban discharge of sewage directly into our watercourses.
Apus 2 , Common. V good!
Claus: Constellation - the boat may hopefully be a star, following in Craic’s wake.
A genus of bird,absolutely correct.
Not Lepidurus apus ; although I too have been frequently referred to by my colleagues as a living fossil!
The academic, computer and ‘Android’ references I appreciate as much thought has gone in to this. Thank you for your erudite and comprehensive answer.
Final solution tomorrow.
