Family life continues for peregrine falcons atop a Nampa sugar factory as the Idaho Department of Fish and Game banded four juvenile birds there.

The young birds banded June 2 - three males and a female - were 28 days old, said biologist Ed Levine. Peregrines, an endangered species, usually hatch two eggs, with four being the high average.The male parent came from the first Boise release at the West One Bank tower in 1988. As indicated by her leg bands, the adult female was also released after being hatched, but Levine has not examined her bands closely.

The first female at the nesting site in Nampa fell into a smokestack last summer, leaving the male, who attracted the current mate in October.

Amalgamated Sugar plant manager Bill Doramus said the two adults have been "cleaning up the pigeons in the area" and are enjoyed by the employees. The young birds should begin flying in two more weeks and hunting on their own in six weeks.

Nine pairs of peregrines have been verified in Idaho, one of them new this year. All are mature adults, upping the odds natural reproduction will increase. Fish and Game will release more captive-raised falcons at six locations this year.
