YELLOW-CROWNED WARBLER, OR MYRTLE-BIRD. 361 
it is rendered, at times, doubtful to which of these several genera they 
ought to be referred. They principally inhabit forests or thickets 
and some affect watery situations or reed marshes. Many are remark- 
able for the melody of their song, and the sprightliness of the airs, 
which in the period of incubation they almost incessantly pour forth. 
The Nightingale, so celebrated for his powerful, varied, and pathetic 
lay, as well as the humble, but tuneful Robin Red-breast, belong to 
this highly vocal genus ; and though many species seek out the arc- 
tic solitudes in which to waste their melody, or sooth alone their 
mates, yet other species may be numbered among the more familiar 
tenants of our gardens, groves, and orchards. Living almost exclu- 
sively on the winged insects of summer, which they dexterously 
catch in the air, or pick from off the leaves, they migrate to the south 
in autumn, and pass the winter in the warm or tropical regions. 
Some exist, more or less generally, on berries in the latter end of 
the year, and consequently find means thus to winter in the milder 
climates which are exempt from severe extremes. Among many of 
the species, the more active and vigorous male, intent on the object 
of his migration, precedes the arrival of the female.
