A few days later the chicks were up and standing on the edge of the nest. The adults walked around on the ground beneath them making lots of noise as if to encourage them to start hunting down their own dinner.
Finally one of the chicks flapped his wings and jumped! He landed about 30 feet away next to our wood shed and the adults flew right over to him with chirps of congratulations. The other two stayed in the nest for several more hours, probably happy to have a little more space but it seemed that the adults were no longer bringing bugs to the nest. So they screwed up their courage and dove out into the world.
