vania. Our only knowledge of its nest is derived from Mr. Audubon, who observed 

 these Hawks in the Great Pine Forest of Pennsylvania, and on the banks of the 

 Niagara River, near the Falls.' He describes it as placed on the branches of a tree, 

 and near the trunk. This nest was one of great size, and resembled that of a Crow 

 in the manner of its construction, but was much flatter. It was made of withered 

 twigs and coarse grass, with a lining of fibrous strips of plants resembling hemp. 

 Another, found by Mr. Audubon, in the month of April, contained three eggs ready 

 to be hatched. In another, the number was four. The only specimen of this egg 

 that 1 have ever seen was one from Northern Ohio, near Cleveland. Its measure- 

 ments are 2iV by Irf inches. In its shape, it is nearly spherical; its surface is 

 rough and granulated; its ground color is a soiled white with a hardly perceptible 

 shade of bluish. It is marked u-regularly vsdth large but quite faint blotches of drab 

 and yellowish-broAvn.
