Wildlife biologists in Denver, inspired by the peregrine program in downtown Salt Lake City, planned Wednesday to release five peregrine falcon chicks at a site atop a downtown building.

Bob Walters, non-game biologist with the Utah Division of Wildlife Resources, said the Denver experiment can be traced to the success of the Utah program, in which endangered falcons have nested for the past three years.The Colorado birds will soon take their first flights, Walters said. In some ways, the peregrine program there is not as advanced as Utah's, where adult falcons nest and raise their young.

Falcon chicks in Denver will be put out in an area where adults haven't colonized.

"Those young birds are not going to have the benefit of adults to help them learn to fly and to feed them," Walters said.

Meanwhile, the two male falcons hatched this year at the aerie on Hotel Utah are happily chasing down prey, along with their parents. "They're up in the air and there to stay," Walters said.

Interested pedestrians can visit a small "lemonade stand" where information is available about the avian celebrities. The stand is moved around, but usually around Main Street and South Temple.
