Both sexes have a black and white wing-patch, or speculum, that is distinctive in flight. |
The audit found a practice nurse had been disinfecting but not sterilising an instrument known as a speculum. |
Ecchymoses and minor lacerations at peri-introital and posterior fourchette may also recur after coitus or during a speculum examination. |
Both sexes have orange feet and a blue speculum, or wing-patch, bordered in white on two sides, best seen in flight. |
The latter is important because dabbling ducks have a coloured area in the wing called the speculum. |
For examination, use the largest speculum on the auroscope that will comfortably fit into the ear. |
