| Abstract |
Bald eagles (Haliaeetus leucocephalus) nesting in the Apostle Islands National Lakeshore and along the Wisconsin shoreline of Lake Superior produced an average of 0.8 young/occupied nest and had an average nest success of 57% during 1983-1988, compared to 1.3 young/occupied nest and 77% nest success in inland Wisconsin. Contaminant levels in nestling bald eagle carcasses collected from nests near Lake Superior were higher than those collected inland, suggesting local contamination. Prey remains collected at nests consisted of fish (50%); birds, primarily herring gulls (Larus argentatus) (48.4%); and mammals (1.2%). Organochlorine and polychlorinated biphenyl (PCB) residues were present at low levels (DDE: means = 0.07 micrograms/g wet wt, PCP: means = 0.21 micrograms/g wet wt) in fish. Herring gulls contained higher concentrations (DDE: means = 5.5 micrograms/g wet wt, PCB: means = 16.95 micrograms/g wet wt) and appear to be the major source of elevated contaminant levels in bald eagles nesting near Lake Superior. |

Attention Score in Context
This research output has an Altmetric Attention Score of 6. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 29 May 2023.
All research outputs
#4,968,506
of 23,806,312 outputs
Outputs from Archives of Environmental Contamination and Toxicology
#245
of 2,093 outputs
Outputs of similar age
#4,575
of 60,953 outputs
Outputs of similar age from Archives of Environmental Contamination and Toxicology
#3
of 18 outputs
Altmetric has tracked 23,806,312 research outputs across all sources so far. Compared to these this one has done well and is in the 76th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 2,093 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.6. This one has done well, scoring higher than 76% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 60,953 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 85% of its contemporaries.
We're also able to compare this research output to 18 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 72% of its contemporaries.
