Pied-billed Grebes rarely fly. They make a slow dive frequently, especially when in danger, diving to about 20 feet or less. They dive for about 30 seconds and may move to a more secluded area of the water, allowing only the head to be visible to watch the danger dissipate. This frequency in diving has earned them the description of being reclusive or shy in nature. It has also earned them nicknames like "hell-diver. I think they are adorable.
