Title: Habitat associations of ducks during different phases of the breeding season
Abstract: Habitat use of mallard Anas platvrhynchos , teal A crecca. wigeon A penelope and goldeneye Bucephala clangula was studied m southern Finland during 1988–1991 Emphasis included evaluation of the importance of food and vegetation structure and revealing of the patterns of habitat use throughout the breeding season Average lake scores of pairs, broods, and juveniles of all species were on the luxunant end of a principal component analysis axis describing habitat structure A more detailed examination, however, revealed clear differences in habitat distributions both between and within species Generally, habitat distributions seemed to shift toward the luxuriant from pairs to broods However, goldeneye juveniles used both the most luxuriant and the poorest habitats more than expected When all phases of the breeding cycle are considered, habitat luxuriance seemed to be more important for dabbling ducks and nektonic invertebrates more important for the goldeneye Emerging insects were most important to the teal
