impossible. The nest is an extremely well-constructed 
affair of fine grasses, fibers, dry leaves and bits of bark 
fiber, lined with fine grasses or bark fiber. Like the other 
members of the family, the nest is suspended between 
the fork of a small branch, and is deeply cupped. The 
eges number from three to four, a dull glossy white,

consider them a beneficial bird in keeping down the many 
insects found amongst our cultivated shade trees.

mass of spider-webs on its outside attracting my attention. 
The nest was in a spruce pine tree in the thick pine woods,
