IPL Indy portion of the report.
"22. IPL Harding Street Power Plant, Indianapolis, Marion County – This site is 4.5 miles south of the center of Indianapolis and the Market Tower territory. A nest box was installed on the roof of the tallest building at this power plant along the White River in 1999. An unbanded, immature female and a banded male were first noted around the nest box in 2001, but nesting did not occur. Four young were raised the next two years and the adult female was captured and banded in 2002. Roof work after the 2003 nesting season forced us to relocate the nest box. Although a pair was seen in early 2004, nesting did not occur in the new nest box but may have taken place elsewhere. In 2005, the same pair was located 1.3 miles north at the Southside Landfill. The nest site was a large horizontal pipe near the top of an abandoned grain mill. Although chicks were present, the attempt later failed. The nest box was relocated to its original location at the Harding Street plant prior to the 2006 breeding season. That year birds were originally observed at the Southside Plant, but it could not be determined if a nesting attempt occurred there prior to the building being demolished. However, a late nesting or renesting attempt took place at the power plant box with two chicks fledging in early July. A pair was present in 2007 but a nest was not found. From 2008-2013, nesting was successful each year at the Harding Street nest box with five chicks raised in 2008. An internet camera was installed in 2011. At least two females and three males have nested at this site. During one year, the pair likely consisted of a mother and her son."

IPL Petersburg portion of the report.
"24. IPL Power Plant, Petersburg, Pike County – A nest box was installed on the roof of this power plant along the West Fork of the White River in the fall of 2004. No activity was reported until 2012 when a worker flushed an adult incubating three eggs in late March, but the nest was later abandoned. After the breeding season, the box was relocated due to roof work, but no evidence of nesting was found in 2013, even though adults were occasionally observed. A camera installed in the new box did not show any visitation by peregrines. The adults appeared to be banded but bands could not be read."
