Lost green parakeet named Kiwi in a neighborhood area of Indianapolis.

I lost my green parakeet named Kiwi in the vicinity of my neighborhood in Indianapolis while taking him outside for some fresh air. He flew off unexpectedly, and I've been searching everywhere for him. Kiwi is very friendly and will likely approach anyone if they call him. If anyone has seen him, please contact me. I'm really worried and miss him dearly.
