Sexual Dimorphism and Population Differences in Structural Properties of Barn Swallow (Hirundo rustica) Wing and Tail Feathers.
Sexual selection and aerodynamic forces wella color charm 050 cooling violet affecting structural properties of the flight feathers of birds are poorly understood.Here, we compared the structural features of the innermost primary wing feather (P1) and the sexually dimorphic outermost (Ta6) and monomorphic second outermost (Ta5) tail feathers of bar
