The nest is placed indiscriminately on the ground or in low 

 bushes ; it is rather bulky and roughly made of twigs, vine ten- 

 drils, roots, bark, and leaves, "lined with horse hair and a few 

 feathers " (Davie). Those that I have found in New Jersey were in 

 every case lined with fine black rootlets. 3 to 5 and rarely 6 eggs
