Summary:
Reproduction
among bald eagles in a remote national park in Minnesota was aided when their
nests were protected from human disturbance, according to a new study.
The
study, by researchers at University of Wisconsin-Madison, the National Park
Service and the U.S. Geological Survey, focused on a nest-protection program
that was based on the logical assumption that endangered birds would reproduce
and prosper if people are kept away from their nests.
The
assumption was logical, but unproven, says study author Ben Zuckerberg, an
associate professor of wildlife ecology at UW-Madison. By combining more than
40 years of data from Voyageurs National Park, along the Canadian border, he,
post-doctoral researcher Jennyffer Cruz and colleagues found that the breeding
population of bald eagles at Voyageurs rose from fewer than 10 pairs in the
late 1970s to 48 pairs by 2016.
