All sandpipers (Scolopacidae) switch from mono- to diester preen waxes during courtship and incubution, but why?
Recently, a shift in preen wax composition, from lower molecular weight monoesters to higher molecular weight diesters, was described for individuals of a sandpiper species (red knot, Calidris canutus) that were about to leave for the tundra breeding grounds. The timing of the shift indicated that d...
