Abstract
We evaluated 3 techniques (air jet, flat skin, grab sample) to assess molt in dead waterfowl (green- winged teal [Anas crecca] and king eider [Somateria spectabilis]). The air jet technique was fast and required no specimen preparation. The flat skin technique required lengthy preparation time after which molt was assessed quickly. Both techniques underestimated the extent of molt (P < 0.01). The grab sample technique needed no preparation but involved time-consuming counting to obtain the molt assessment. The grab sample was preferred when study skins did not need to be preserved because it was easy to conduct, and it was repeatable and more accurate than the other techniques.
