Dragonflies

I was outside watching this dragonfly fly around my yard. So I got my camera and tried to photograph it in flight, doesn't happen. But it did land on one of two shepherds hooks with our flower baskets. The only hook it would land on though was the one with the metal dragonfly. I did see it land one other place in the tree nearby but every time it landed after that was always on that one with the dragonfly. I wondered if by chance it knew what it was.
