Specificatii
This meticulously researched and photographed account follows three
University of Montana scientists and their interdisciplinary work
with osprey: fish-catching birds with gigantic nests and a family
that functions with teamwork and cooperation. Today the osprey is
studied to monitor the effects of mercury on living things. The
osprey hunts in a very small area around its large nest and so
scientists can pinpoint where mercury is coming from. In Missoula,
Montana, the scientists have been following ospreys for six years,
collecting data on the amount of contaminants found on their
feathers and in their blood. The rivers and streams in Western
Montana are still suffering effects from inappropriate mining
activities performed more than a hundred years ago. This man-made
pollution is still dangerous to people and to wildlife.
