 shallow; made of sticks and twigs, mixed together with corn-husks, grass, moss, and 

 on the inside may be found a few feathers. Sometimes the deserted nest of a crow 

 or that of another hawk is fitted up and used. Mr. J. Parker Norris records a nest 

 occupied first by the Great Horned Owl and afterwards by the Red-tailed Hawk, each 

 year; the young owls leave the nest before the hawk is ready to occupy it. The num-^ 

 ber of eggs laid by this species is two or three, rarely four. Mr. Norris has a series 

 of twenty-seven sets collected in Connecticut, Pennsylvania, Iowa, Mississippi, and 

 Texas; nineteen of these sets are of two eggs, six of three, and two of four.* The 

 time of depositing the eggs in the United States varies according to locality and 

 circumstances, but they are generally laid in March or April, Eggs are found in
