“…3) are similar to levels previously reported for white-tailed eagle eggs from Sweden and Germany (Helander et al 2002; Scharenberg and Struwe-Juhl 2006). From 2005 and further, the growing white-tailed eagle population is in line with the population dynamics of white-tailed eagles in Sweden (Helander et al 2008), Germany (Scharenberg and Struwe-Juhl 2006; Krüger et al 2010) and bald eagles in Canada and United States (Grier 1982; Bowerman et al 1995; Donaldson et al 1999; Buck et al 2005). …”

“…The ∑DDT concentrations were converted to DDE, assuming that DDD and DDT had been transformed to DDE. As the DDE peak is expected to have occurred before 1978, for which no measurements were available in The Netherlands, the DDE trends observed in Sweden (Helander et al 2002) and Germany (Scharenberg and Struwe-Juhl 2006) were extrapolated to our study area. For 1998–2050, emissions as well as degradation of DDE were assumed to be negligible.…”

“…white-tailed eagles ( Haliaeetus albicilla ) and bald eagles ( Haliaeetus leucocephalus ), have extensively been documented (Wiemeyer et al 1993; Bowerman et al 1995; Donaldson et al 1999; Helander et al 2008). Due to the ban on PCBs and DDT and due to conservation measures, most sea eagle populations are currently recovering (Hailer et al 2006; Scharenberg and Struwe-Juhl 2006; Krüger et al 2010). In some countries, however, reproduction rates of sea eagles are still low (Helander et al 2002; Gill and Elliott 2003).…”

Modelling the impact of toxic and disturbance stress on white-tailed eagle (Haliaeetus albicilla) populations

Several studies have related breeding success and survival of sea eagles to toxic or non-toxic stress separately. In the present investigation, we analysed single and combined impacts of both toxic and disturbance stress on populations of white-tailed eagle (Haliaeetus albicilla), using an analytical single-species model. Chemical and eco(toxico)logical data reported from laboratory and field studies were used to parameterise and validate the model. The model was applied to assess the impact of ∑PCB, DDE and disturbance stress on the white-tailed eagle population in The Netherlands. Disturbance stress was incorporated through a 1.6% reduction in survival and a 10–50% reduction in reproduction. ∑PCB contamination from 1950 up to 1987 was found to be too high to allow the return of white-tailed eagle as a breeding species in that period. ∑PCB and population trends simulated for 2006–2050 suggest that future population growth is still reduced. Disturbance stress resulted in a reduced population development. The combination of both toxic and disturbance stress varied from a slower population development to a catastrophical reduction in population size, where the main cause was attributed to the reduction in reproduction of 50%. Application of the model was restricted by the current lack of quantitative dose–response relationships between non-toxic stress and survival and reproduction. Nevertheless, the model provides a first step towards integrating and quantifying the impacts of multiple stressors on white-tailed eagle populations.
