shredded inner bark of the basswood, a few horse, and a number of 

 deer's hairs. The rim is Usnea matted and twined together. The 

 exterior is necked all over with fluffs of cottony spiders' webbing. 



Burtch's nest is described by him as "loosely constructed of fine 

 hemlock twigs and a few pieces of weed-bark lined with fine red fiber 

 such as the Magnolia Warbler and Redstart use. The nest resembles 

 that of the Magnolia Warbler very closely, but lacks the woolly decora- 

 tions."

 Size, average, .68X.50. (Figs. 65,66.)
