Sexing. Pattern of 4th secondary: left male; right female. AGEING It is unlikely to find juveniles in Aragon, so only 2 types of age can be recognized: 1st year/2nd year spring with juvenile flight and tail feathers retained which will be eroded. Male with the outer tertial with a quite broad black fringe on the edge; greater coverts narrow and with rounded, broad white, more or less creamy edged tips. Female with the outer tertial with a quite narrow dull black fringe on the edge; greater coverts narrow and with rounded, narrow white, more or less creamy edged tips. Adult with fresh flight and tail feathers. Male with the outer tertial with a line of pearly grey, a broad line bright black and reduced pale fringe on the edge; greater coverts broad and with squared, very broad white and intensive cinnamon edged tips. Female with the outer tertial with a line of dark grey, a line dull black and a broad pale fringe on the edge often around the tip; greater coverts narrow and with rounded, narrow white, more or less creamy edged tips.

Pattern of greater coverts: left adult; right 1st year. MOULT Complete postbreeding moult acquiring nonbreeding plumage, usually finished late September. Partial postjuvenile moult changing body feathers and tertials, usually finished between October and November. Both types of age, from September, have a partial prebreeding moult acquiring the breeding plumage. PHENOLOGY I II III IV V VI VII VIII IX X XI XII Teal. Female. Ageing.
