Some of these birds build in places besides the ones mentioned. The Robin, 

 for instance, nests in all kinds of places, tree, vine, ledge of a house or anywhere, 

 and cLt any elevation from 2^ to 40 feet. We have seen one try repeatedly to 

 make a nest stick on a sloping water spout. And how the Robin and Thrasher 

 must miss the old rail fences ! The Robin makes no effort at concealment. He 

 will have a score of white cords dangling from his nest in a vine, or a strip of 

 muslin a yard long calling attention to his home in a tree. Eggs, usually 4 ; blue. 



The Catbird, too, will begin by laying a dangling piece of cloth in the crotch 

 of the tree for foundation to his house. Eggs, 3-5 ; green. 



The Brown Thrasher likes a wild crab thicket. Eggs, 3-4 ; pale greenish- 

 white evenly peppered with brown. 



Wren's eggs, 4-7; delicate terra-cotta- white, finely peppered. 



Bluebird's eggs, Z-6; limpid white, faintly tinted with blue, like blue water. 

 Three nests in 1916 had three each. One bird must have alighted skilfully, for 

 the opening was on the under side of a post used as prop to a fence post. 



The two eggs of the Whipporwill and the Nighthawk are speckled and 

 blotched and hard to distinguish from the pebbles on the ground— or on the flat 

 roof where the latter bird sometimes deposits hers. 



With her bill, the Baltimore Oriole weaves a long sack suspended from a 

 high outer limb, using thread, hair, grass, rags and paper, all of dull color. A lady 

 of our acquaintance put out yellow, green and gray yarns, and the Oriole took 

 only the gray. A farmer tells me he has seen one test binding twine with bill and 

 claw, and, if it broke, discard it. 



The Vireo and Orchard Oriole, also, make pensile nests, but they attach 

 them so closely to the under side of branching twigs that you might think they 

 rested on the twigs. Eggs of the former, 3-4, pure white sprinkled with choco- 

 late; of the latter 4-6, bluish, with specks and zigzag lines of brown. 



Out of hemp and grass the Yellow Warbler makes a dainty cup about the 

 size of an unshucked walnut. Like the two last mentioned it builds out on the 

 smaller branches. Eggs, 4-5, greenish, spotted with reddish-brown and wreathed 

 around the larger end with black and lilac.
