Fishes in MZNA-VERT: foraging ecology of the kingfisher. PhD project, Antonio Vilches ...
The Common kingfisher Alcedo atthis L. 1758 is a fish eating bird which is associated with freshwater bodies in well conserved conditions. Currently, there is a negative trend in their European populations, so it is included in the threatened lists of species. This study aims to determine the trophi...

| Summary: | The Common kingfisher Alcedo atthis L. 1758 is a fish eating bird which is associated with freshwater bodies in well conserved conditions. Currently, there is a negative trend in their European populations, so it is included in the threatened lists of species. This study aims to determine the trophic ecology of the Kingfisher in various rivers of Navarra (Spain) to define the important factors in the selection of habitat and assess the impact this bird may have in comercial fish species. ... : This project determined the relative importance of food availability and habitat structure and quality in the presence of kingfisher during breeding, and develop a useful methodology to determine the diet of the species from partial examination of pellets found in the nests. Also, it described the diet and determined, based on the food availability, its fishing strategy (opportunistic or selective) and the impact of the Common kingfisher on both a commercially important fish and conservation species such as the Atlantic salmon. ... |
