A young Great Blue Heron learning to use his wings, and now actually fly.
I watched this juvenile flap like crazy, get some height, and frantically fly to the tall trees on the edge of the swamp.
After a rest he returned to the safety of the nest.
Down below is a swamp, and Alligators. Incentive to make to the trees.
I’ve never seen one not get over there. Still, I’m sure the birds are terrified the first few times.
