Nikola Tesla and his female pigeon

Nikola Tesla the famous inventor and contemporary of Thomas Edisson who never married, loved to feed pigeons during his old days. His lines are quite interesting:

" I have been feeding pigeons thousands of them for years. But there was a one, a beautiful bird, pure white with light grey tips on its wings; that one was different.  It was a female. I had only to wish and call her and she would come flying to me. I loved this pigeon as a man loves a woman, and she loved me. As long as I had her, there was a purpose to my life."
