the crown. The above colorations are the extremes, between 
which there are various intermediate forms. It is remarkable 
that the eggs, though so variable, are very generally character- 
istic of the birds, and unlike those of other warblers. In 
Eastern Massachusetts four or five eggs are laid about the first 
of June, but no second brood is raised unless some accident 
befalls the first. 
(c). The Yellow Birds are the most common and familiar of 
all our warblers ; and who is there that does not, or who ought 
not to know these beneficial and charming little birds, who are 
so pleasantly associated with the arrival here of actual spring, 
since generally in the first week of May they come from the 
South? Throughout the summer they are to be found about us, 
but when autumn comes they leave us, and generally, before 
the first week of September has passed away, they have gone. 
Yet they are very hardy, and stray to the Arctic shores, though 
hardly anywhere common to the northward of Massachusetts, 
where they are, in most parts of the State, abundant. They 
inhabit pasture-land and cultivated grounds, being not infre-

through our orchard-trees, shade-trees, and shrubbery. They 
never seek for these insects on the ground, or in the higher 
tree-tops, and rarely seize them in the air, but whilst pursuing 
them continually move among the lower branches, occasionally 
taking short flights from one place to another. 
(d). The Yellow Bird’s song is simple, yet very pleasing, 
and one does not become tired of it, though repeated often, as 
it has several variations. It nearly resembles the syllables 
weé-chee-weée-chee-weé-i-u, but is like the song of several other 
warblers. The loud chirp of the Yellow Birds is often heard 
from the branches, among which they are busy, and often is 
repeated plaintively, when their nest is disturbed. 
_ Though probably less familiar toward man than many people 
suppose, the Yellow Birds do not repel his advances, and cer-
