Zn distribution within a Flesh-footed Shearwater beast feather. The line profile (A) derived from the Zn map shown in (B) illustrates the inter-individually consistent periodicity in elemental Zn distribution. The red line shows the observed pattern after smoothing to reduce noise. The mean of Zn distributions is shown (C). The individual Zn distributions were taken along the rachis of each sample, normalised to length and intensity then used to create an average distribution across feather from multiple birds (n = 4) demonstrating that the number of Zn bands is consistently 30–32.
