    It is a bit early for fledging here. 😉 But I do notice that they mostly have their backs to the camera. And some have the feathers on

    their necks so blown around that you can see the white of their feather roots. So it must be a furiously windy day 😃

    Thank you Joan--we thought fledging was right when they stepped away from their parents (like a bird leaving a nest).

    When is it technically fledging?

    When songbirds fledge they take their first flight. When penguins fledge they take their first swim, with waterproof feathers.

    Before the adult feathers grow in, and they lose the baby down, they are completely dependent on their parents.

    Once they can go to sea, they are completely on their own with all the other newly mature fledges. They must swim for the first time, find food, avoid danger, etc.

    Only a small detail to add and that it that Adelie chicks fledge at around 52 to 61 days old.

    You all are great. That was a perfect explanation. It makes sense that fledging is when they are fully independant. 😄
