What attracts digs, cats, kids, and pet birds to me?

It hapens all the time. I was in a park texting once. Some lady had a parrot (ok sone bird like a parrot). It hopped off her shoulder onto me. I was startled to say the least.

Added (1). "dogs" - Typing on my iPhone

Probably scent (pheromones) and/or body language. Happens to me with cats and dogs. And birds sometimes.
