Emberiza shoeniclus - sexing autumn

Common Reed Bunting / Sävsparv

SEXING:

After completion of post-juvenile moult, most birds are readily sexed using the below criteria (rarely, a few birds may be more problematic). Further characters are given in Svensson (1992).
Male, 1cy, September. A pure white collar is present in the nape of males. This may be partly visible, like here (just behind the ear-coverts), or fully concealed by buffish feather tips when fresh. [1ET80494]
Male, 1cy, November. The presence/absence of white in nape may be checked by gently lifting the feathers. [1ES24453]
Female, 1cy, October. In females, no pure white is seen in the nape. A few individuals may show brownish dirt-white hidden under more extensive buffish tips. [1ES79590]
Male, 2cy+, November. Note that adult males generally attain a rather dull and descreet plumage during autumn. [1ET29303]
Male, 1cy, September. In males, the crown feathers show wide jet-black centra and bases, distinctly demarked from the buffish tip. [1ET80494]
Female, 1cy, October. Female crown feathers show a smaller and narrower dark brown (brownish-black) centre, more diffusely demarked from the buffish tips. [1ES23071]
Male, 1cy, September. The rump feathers in males show a rather cold grey colour, in fresh plumage concealed by brownish-buff tips. [1ET80494]
Female, 1cy, October. Female rump feathers usually lack grey feathering, but a few may show smaller greyish suffusions.[1ET80658]
Male, 2cy+, November. An adult male showing extensive presence of grey in rump. [1ET29303]
