Nesting Site. "It always nests on the ground, generally on a 

 steep hillside in the woods. A stream of water or a swamp seem to 

 be a desirable condition." (Jackson. 3 ') 



Ladd 4 states that the nest is placed at the foot of either a sapling 

 or small bush, not necessarily on a hillside but sometimes on level 

 ground in open places with little shade. 



Nest. "The nest is invariably lined with the red flower stalks 

 of the hair moss (Polytrichium)." (Jackson. 3 ) Ladd confirms this 

 habit and adds: "Sometimes fine grass and horse-hair are used as 

 part of the lining." The body or outside of the nests is composed of 

 leaves only. Nests taken by J. N. Clark at Saybrook, Connecticut 

 (C. W . C.) are composed of decayed leaves and lined with stems of 

 maple seeds. 



Eggs. 3 to 6, usually 4 or 5. Ground color white with a wide 

 variation in markings from sparingly to profusely marked with spots, 

 specks, and blotches of chestnut, lavender, light and dark reddish, 

 with a tendency to form wreaths around the larger end, but in most 

 cases a nearly evenly marked egg. In shape some are rounded oval 

 and others much pointed. Size; average, .6o.x.53; extremes, 7SX.58, 

 .64x48. (Figs. 9-11.) 



Nesting Dates. Iredell County N. C., May 10 (/. P. N.) ; West 

 Chester, Pa., May 26- June 15 (Jackson) ; Waynesburg, Pa., May 

 i6-June ii (Jacobs); New York City, May 20 (F. M. C.) ; New 

 Haven, Conn., May 25-June 19 (Bishop).
