After decades of being on the endangered species list, Indiana removed the Peregrine Falcon this week.
The 10-year nesting site will remain undisturbed during construction, officials say.
Wildlife biologists banded 44 peregrine falcon chicks this year, compared to 38 last year.
The four birds hatched on the Market Tower in Indianapolis have been named Dox, Edge, Bailey and Luka.
The Indiana Department of Natural Resources is seeking information involving the shooting and subsequent death of a 16 year old Peregrine Falcon.
