Although they were at one time plentiful through out the state of Minnesota, the osprey had all but disappeared from the southern half of the state by the early 1900's. In 1984 the Hennepin Parks Association, now the Three Rivers Park District, began a release program to reintroduce nesting osprey into the Twin Cities Metro area. They set up osprey nesting platforms in suitable habitat and began to release young birds that had been taken from northern Minnesota. Over an eleven year time frame, 1984-1995, they released 144 young osprey into the area and put up around 100 nesting platforms. Many of these birds returned to the Twin Cities after migration and when they reached maturity, 3-4 years, they began to nest in the area. In 2010 their were over 60 active nesting territories in the Twin Cities and the number has continued to grow. Around 85% of the population is banded.
