216 FULVOUS OR CLIFF SWALLOW. 
a male in summer plumage, the only specimen brought by 
Long’s exploring party ; hence we are unable to give any posi- 
tive information relative to the female and young, though, 
from analogy, we must believe them in great part destitute of 
the blue colour, and otherwise less brilliantly adorned. 
This species appears to be rather rare; it is found along 
the Arkansaw river, near the base of the Rocky Mountains, 
during the summer months; they frequent the bushy valleys: 
keeping much in the grass, and seldom alight on shrubs or 
trees. In this respect also they resemble the indigo-bird, and 
probably their habits are the same, although the note is entirely 
dissimilar.

Wir the exception of a very imperfect description, little 
was known relative to this interesting bird anterior to Loneg’s 
expedition to the Rocky Mountains. Oue of the notes annexed 
to the account of that journey contains an excellent descrip- 
tion of this swallow, with a notice of its habits, and remarkable 
manner of building. Mr De Witt Clinton has recently pub- 
lished a paper on the same subject, accompanied by some 
observations from Mr Audubon. Combining what these gen- 
tlemen have made known with the information previously 
given by Vieillot and Say, we can present a tolerably com- 
plete history of the cliff swallow. . 
Some doubts having been entertained whether the Hirundo 
lunifrons of the Rocky Mountains be the same species as the
