Wintering diving duck populations in the Öresund, Southern Sweden, in relation to available food Resources.
(2005) In Wildfowl 55. p.61-76- Abstract
- Intensive surveys of staging and wintering diving ducks in the Öresund area,
southern Sweden, were undertaken during the winters 1995/96, 1996/97 and
1997/98 as a part of the Environmental Impact Assessment (EIA) related to the
establishment of a Fixed Link (bridge–tunnel–artificial island) between Sweden
and Denmark. Monitoring of the benthic fauna made it possible to compare the
calculated food requirements of the diving duck populations with their food
resources. Overall, the diving ducks (mainly Tufted Duck Aythya fuligula, Scaup
Aythya marila and Goldeneye Bucephala clangula) consumed between 2.6% and
4.6 % of the standing crop of suitable food organisms. It is, however, probable that higher proportions... (More) - Intensive surveys of staging and wintering diving ducks in the Öresund area,

A prolonged period of ice cover during one of the study years made a large proportion of the feeding areas unavailable, but the main mussel beds were still free of ice because of strong currents so this had only limited impact on the food availability for the ducks.
