Fig. 3. Mean breaking force (A) and mean cross-sectional area (B) of unmelanized
(open circles) and melanized (closed circles) bands of barbs as a function of
mean fractional distance along the feather, where `0' represents the proximal
end and `1' represents the distal end of the feather. Breaking force and
cross-sectional area differed significantly between bands (ANOVA,
P<0.001). Mean values for bands sharing the same letter were not
significantly different (a posteriori; P>0.05); mean
values for all other bands were significantly different.
