This is a report that John Castrale, Indiana's DNR non game bird biologist, submitted to the Indiana Audubon Society in February 2014. The Peregrine section begins on page 2 and Indy Market Tower is on page 12.
Below is the Indy Market Tower portion of the report.
"21. Market Tower, Indianapolis, Marion County – Sightings of peregrine falcons in downtown Indianapolis date back to 1986 and four nest boxes were erected soon thereafter and have since been removed. The original release of peregrines in Indiana occurred in Indianapolis in 1991. Following the release, a nest box was erected on the ledge of the 31st floor of the Market Tower facing east towards Monument Circle, a half block to the east. A juvenile male was first sighted in 1994 and nesting occurred the following year. This site has successfully produced young each year through 2013 and leads the state in number of young produced (65) and mean number of young fledged annually (3.4/nest attempt). Nesting has taken place in the nest box each year except for two. In 1997, the pair moved to a gutter on the south side of the War Memorial and in 2003 the pair relocated to a gravel alcove on a building at 30 South Meridian Street. These locations are 1750’ northeast and 725’ southeast of the Market Tower and at a much lower elevation. Two different females and two males have nested in downtown Indianapolis. The original male, Kinney, holds the distinction of living longer (19 years, 2 months) than any other male in the Midwest and raising more chicks (61) than any other Midwestern peregrine. Female KathyQ has also produced more chicks than any other female in Indiana. A camera at this site since 2001 has allowed thousands of people to follow these birds."
