Résumé :
|
[Diving ducks wintering on the coasts of Scania showed an uneven distribution that was partly caused by differences in the abundance of food and the availability of suitable resting places, partly by tradition. Differences in diving ability between species were reflected in the local distribution. The main food of the bottom-diving species was Mytilus edulis, but there was variation in additional food items amongst the different species. Calculated rates of exploitation in different parts of the study areas showed that food resources were sufficient for much larger numbers of ducks than were present.]
