nest is built on the low branch of an oak, 
or auv situation that excites their lancv. 
It is constructed of twigs, lichens, coarse 
■ grass, wool, etc., and lined with hair. The 
eggs, 4 or o, are of a creamy white ground 
color, spotted with brownish and purple of 
two shades, and are oblong, though quite 
pointed at the smaller end. They measure 
1 by .70 of an inch. The birds are quite 
easily tametl if taken when young, and
