1cy male (cairii) October. Innermost two TT are post-juvenile (in contrast to the juvenile longest T) and the shorter one shows a typical male pattern with silvery white edges. The same pattern would also have shown on any post-juvenile SS, if present. Birds with this tertial pattern should safely be sexed as males, but it should be noted that the central T, although being post-juvenile, still lacks white. If the shorter T (with the white edge) would have been unmoulted juvenile, such a bird would easily have been mistaken for a female. In order to reduce such a risk, it is preferable to base the sexing of females on more than one postjuvenile feather. [CL25200]
