Actually, determining failure from static bird loading is relatively easy to
calculate. Any introductory statics (or strength of materials) book will
explain the basic techniques. It is really only a couple of equations to
calculate the deflection, and the number of birds required to cause an
element to fail. The only things needed are the number of birds, the weight
of the birds (easy to estimate from any bird book), the size of the element
(diameter, length and wall thickness), and the alloy (it can probably be
assumed to be 6063-T6).....
The actual calculation is left as an exercise for the student......

"WOLF"???? Good heavens, TOM will be spinning in his grave. You might
be wise to correct the spelling lest the instrument seek you out and
apply the appropriate remedy for this sacrilege :-D
