habits of the cunning magpie and predacious carrion 
crow. 
The nest of the cushat is a flimsy fabric, being 
a mere platform of small twigs loosely interwoven, 
so open, indeed, that the eggs, in one newly built, 
and before it becomes thickened by the droppings of 
a previous brood, may he seen through it from be-

frequently happens, where the incubating bird is sud-

The site selected for nidification is various, and no 
tree or bush seems to come amiss at certain periods 
of the year. In early spring, however, and before 
the deciduous trees acquire their umbrageous and 
leafy covering, fire, and other evergreens, are pre- 
fenced, on account of the better concealment and pro-

nest is necessarily placed at various elevations, at 
one time being far removed from the ground, as 
when it is built near the summit of a lofty spruce, 
or in the thick foliage of a beech or sycamore, at an-
