Tb117: Techniques For Using The Growth And Behavior Of Imprinted Ducklings To Evaluate Habitat Quality, Malcolm L. Hunter Jr., Jack W. Witham, Jody Jones
Technical Bulletins
We developed a technique for evaluating duckling habitat quality that is based on two assumptions. In good habitat young birds (1) grow rapidly and thus are better able t o survive stresses such as inclement weather, and (2) spend relatively less time moving about in search of food and more time resting and thus are less conspicuous to predators. We imprinted artificially incubated and hatched ducklings by being present at the time of hatching; i.e., the ducklings thought we were their mother. Ducklings were split into broods and placed on ponds where their growth was measured and their behavior monitored …

The incidence of lead shot in l ,687 lesser scaup (Athya affinis) and 416 ring-necked ducks (Athya collaris) in spring migration in Minnesota and the implications as related to the bird population and hunting harvest the preceding fall are considered in this study. The ducks, which were examined for shot by photofluorographic radiography had died as a result of oil pollution on the Mississippi River in the vicinity of Red Wing in the spring of 1963. The birds were separated into two age groups and by sex. Yearling lesser scaup had a body shat incidence (proportion of birds containing shot) …
