who often precede the arrival of their more tardy mates. # 
Their wintering resort appears to be rather the West In- 
dies than the tropical continent, as their migrations are 
observed to take place generally to the east of Louisiana, 
where their visits are rare and irregular. f At this season 
also they make their approaches chiefly by night, obeying, 
as it were, more distinctly, the mandates of an overrul- 
ing instinct, which prompts them to seek out their natal 
regions ; while in autumn, their progress, by day only, is 
alone instigated by the natural quest of food. About the 
1st of May the meadows of Massachusetts begin to re- 
echo their lively ditty. At this season, in wet places, and 
by newly ploughed fields, they destroy many insects and 
their larvae, but while on their way through the Southern 
States, they cannot resist the temptation of feeding on the 
early wheat and tender barley. According to their suc- 
cess in this way, parties often delay their final northern 
movement as late as the middle of May, so that they ap- 
pear to be in no haste to arrive at their destination at any 
exact period. The principal business of their lives how- 
ever, the rearing of their young, does not take place until 
they have left the parallel of the 40th degree. In the 
savannahs of Ohio and Michigan, and the cool grassy 
meadows of New York, Canada, and New England, they 
fix their abode, and obtain a sufficiency of food throughout 
the summer, without molesting the harvest of the farmer, 
until the ripening of the latest crops of oats and barley, 
when, in their autumnal and changed dress, hardly now 
known as the same species, they sometimes show their 
taste for plunder, and flock together like the greedy and 
predatory Black-birds. Although they devour various
