"As we monitored eagles in the 20 years the Nongame Wildlife Program has been watching them here in Minnesota, we have seen a dramatic recovery. The birds came back by reoccupying places of habitat particularly along the major rivers and stream corridors in Minnesota, so the St. Croix, Mississippi and Minnesota rivers were those places the bald eagles returned to to nest in the first instance of their recovery. Clearly these ribbons of habitat with big trees and clean water and lots of good fish to eat that attracted these recovering eagles and restored our population to where in Minnesota now we have more than 700 nesting pairs and a lot of them are along our rivers and stream corridors.
"The peregrine falcon is another success story that relates to rivers and streams. East of the Mississippi River they had entirely disappeared from the consequences of DDT toxicity. Now we see these birds are occupying the very same nest sites along the Mississippi river cliffs that they occurred in 60 years ago and it's really quite amazing if we guard those special areas, those special habitats and keep them for wildlife the animals will appreciate our efforts and in this case they occupy the historic ranges that they were in previously."
