I'd add weight and aspect  ratio to that, and do an analysis of variance. 
Plus, confirm the mechanism by which birds open those slots.  I doubt that 
albatrosses for example, can open such slots.  Birds that open such slots 
are simply modifying the balance between profile and induced drag 
(increasing the effective aspect ratio and the Ozwald Efficiency factor).
