LANSING, Mich. (AP) - Fifteen peregrine falcon chicks were fitted with leg bands in southeastern Michigan this spring, enabling scientists to track their movements.

Peregrine falcons risked extinction in the last century as the pesticide DDT made their eggs unnaturally fragile. The entire population east of the Mississippi River disappeared by the late 1960s.

Since then, the species has recovered to the point that it’s no longer on the federal endangered list, although it’s still endangered in Michigan.

The state Department of Natural Resources places leg bands on falcon chicks. Scientists monitor their dispersal, migration, life span, reproductive success, behavior and population growth.

Southeastern Michigan has 21 known nest sites. Ten of them successfully hatched chicks, and 23 chicks fledged.

In 2013, there were 47 nest sites in the entire state.
