A fluffy brown hawk was screeching for several days in our yard. It would fly to a branch on a scrag tree and not leave for over an hour. One morning an adult hawk [I fantasied it was the mother] flew over the scrag tree shrilly screaming. The youngster didn't move. The adult hawk swooped into the mass of trees, grabbed hold of the branch beneath the youngster and hung upside down for over 20 minutes screaming at it. Finally the little hawk took flight in a clumsy manner that had it almost plummeting to the ground. The large hawk immediately swung upright on the branch and took flight.
