“…One of the species of wetland birds whose research could contribute to the assessment of the state of the environment in Poland is the Tufted Duck Aythya fuligula (Linnaeus, 1758), the species of diving ducks Aythyini (Delacour et Mayr, 1945) [Nieoczym et al 2021]. They are omnivorous animals, feeding mainly on seeds and aquatic plants as well as small crustaceans, bivalve molluscs, snails and insect larvae [Sekiya et al 2000, van Nes et al 2008, Rose and O'Brien 2020. These birds obtain their food by foraging mainly in the bottom zone at the depth of up to 6 m [Sokołowski 1977].…”

The purpose of this work was to perform morphometric characteristics of the Tufted Duck Aythya fuligula obtained in Western Pomerania, according to their sex and age. The research material consisted of 197 Tufted Ducks obtained in December 2013. The biometric characteristics was performed on the basis of 20 measurements of linear and mass quantities. All internal organs measured and most of the individual body parts of the Tufted Duck were slightly larger in the case of males. Despite the differences in the body size of males and females, the studied birds showed similar variability in both length and mass. The differences between adult and young Tufted Ducks were not so well defined. Adult Tufted Ducks had significantly larger body mass, pectoral muscle mass and lung mass than juveniles. No significant differences were found in the linear values of the examined features.

Seeds consumed by waterfowl in winter: a review of methods and a new web-based photographic atlas for seed identification

International audienceDiet quantification has long been and still is one of the first steps undertaken when studying the basic ecology of a species. We conducted a literature review of the techniques used to study and analyse diet among waterfowl. Even though the identification of food items is the most challenging task performed when studying granivorous waterfowl diet, there is a general lack of reference collections to support the taxonomic determination of food resources. We present here a collection of indexed digital pictures of seeds from the reference collections of several French programs of research into waterfowl diet. Photographs are ranked by seed size or by taxonomic key to ease seed identification. This collection is freely accessible at the website http://www.cebc.cnrs.fr/atlasofseeds.html, and it can help wildlife researchers studying the diets of granivorous species to determine food items. A complete bibliography is also provided, including recent papers in archeobotany and useful websites
