Other Activity: From a distance we could see the nestling practicing flapping at the nest and the adult on the post. As we paddled closer, both were calling but we were down so low in the marsh today and couldn't see until we got pretty close to the nest. When we got to an open viewing spot the adult called and the nestling tucked down a bit in the nest. This nestling is smaller than the Brophy or Dean young.
