and its tail less forked. Its plumage, however, is 
nearly the same, the upper parts of the body being 
jet-black, and the under parts white. It would be 
almost impossible to preserve this bird in confine- 
ment, as it feeds entirely on insects. 
154. It frequently makes its nest under the eaves 
or cornices of houses, or more frequently in boxes 
placed for the purpose. In summer, great flocks of 
them are always seen upon the steeples of churches, 
all striving for the highest place upon the very top 
of the spire. 
THE PIED FLYCATCHER. 
155. This bird is nearly five inches in length : 
the bill is black ; the eyes are hazel ; the forehead 
is white ; the top of the head, the back and tail, are 
black. 
156. They build their nests in holes of trees ; the 
parent birds incessantly feed their young with small 
flies, which they are very expert in catching. From 
this they derive their name.
