evergreens, usually pines, at a considerable distance from the 
ground. The materials used in its construction are leaves, strips 
of bark, weeds, and caterpillars’ or spiders’ web, with the lining 
of hair and feathers. 3 to 4 and sometimes 5 eggs are laid ; they

of brown and lilac gray, most of which form a wreath round the

times lacking. Length—4.75.

The nest is composed of fine grass, plant fibre, and down, 
and lined with fine roots and hair, resembling to some extent the 
nest of the yellow warbler. It is placed near the ground, in 
scrubby bushes or saplings, often in young cedars. 3 to 5 eggs 
are laid; they are white, with a few brown or purplish brown 
and faint lilac spots wreathed round the larger end. Size—
