animal fur and with feathers. Both birds worked together in con- 

 structing their nest, beginning on the nth of April, and on the 

 27th of the same month this contained seven eggs. The nest was 

 not covered at the top, in the manner of the Carolina Wren. -••** 

 The eggs measure .67 by .50 of an inch in their average pro- 

 portions, resembling somewhat those of the Carolina Wren, but 

 having a lighter ground, with fewer and finer markings of slate 

 and reddish-brown. The ground-color is of a pinkish-white."

HOUSE WREN. 



This is a common species throughout the United States, from 

 the Atlantic to the Rocky Mountains. In some localities however, 

 it is not always abundant. It builds its nest under the eaves of 

 houses, in corners of the barn, martin-boxes, and in fact they are 

 found nesting in every conceivable cavity or crevice. The nest is 

 composed of a mass of miscellaneous rubbish, sticks, grasses, 

 hay and other convenient materials. Within this they construct 

 an inner nest composed of finer substances, lined with feathers, 

 fine dry grasses, and sometimes with the fur of small quadrupeds. 



The eggs are usually seven in number, sometimes nine, of a 

 rounded-oval shape. Their ground-color is white, thickly dotted 

 with fine spots of reddish-brown, with a slight tinge of purple. 

 Their shape varies from nearly spherical to an oblong oval, some 

 measuring .60 by .55, others with the same breadth having a 

 length of .67.
