Compton (A) Br (B) and Zn (C) patterns Streaked Shearwater feathers (Calonectris leucomelas). Three breast feathers from three individual Streaked Shearwater, scanned simultaneously in high resolution, demonstrate the distinct banding of the Br distribution and regular patternation of Zn along the length of the rachis. Maps of Compton inelastic scattering were constructed from the XFM to inform the anatomy and composition of each sample. The intensity of Compton scatter is equivalent to the mass and density of material encountered by the incident beam and was used to correlate changes in elemental concentration and distribution with potential changes in the composition of each sample. The deposition pattern of the elements Br and Zn is independent of regional mass and density in the feathers.
