Across Pennsylvania breeding birds are hatching eggs and feeding young. As the nestlings grow the nests become crowded, a sure sign that the babies will leave soon.
Baby birds in hollow trees have an amazing way of leaving the nest: they climb up the inside of the hole and jump! This is true of chickadees, screech-owls, woodpeckers and wood ducks. But ducklings have no flight feathers and they jump away. That’s OK, they’re built for it.
Though the video doesn’t show it, the ducklings waddle to the water where their mother calls and waits for them.
