attached to the supporting twigs, mixed with some slender strips of 

 fine bark and pine-leaves, and thickly bedded with the down of wil- 

 lows, the nankeen wool of the Virginia cotton-grass (Eriophorum 

 Virginicum), the down of fine stalks, the hair of the downy seeds 

 of the button-wood (Platanus), or the papus of compound flowers, 

 and then lined either with fine bent grass (Agrostis), or down, and 

 horsehair, and rarely with a few accidental feathers." 



The eggs are usually four in number, sometimes five: 

 they vary in color from creamy-white, with numerous spots 

 and blotches of different shades of brown, to a grayish-white 

 with a greenish tint, and marked with the same spots and 

 blotches ; these markings are thickest at the larger end of 

 the egg, where they are often confluent. Dimensions vary 

 from .67 by .50 inch to '.64 by .50 inch. The habits of this 

 bird are well known ; and its genial nature and confid- 

 ing disposition have rendered it a great favorite with the 

 farmer.
