tween them; but I am induced to think that they keep apart from the old 

 birds during the first winter, when I have thought I could yet perceive an 

 inferiority in their flight, as well as in the loudness of their notes. 



This species has no song, properly so called, but merely a twitter of short 

 lisping notes. In autumn it at times alights on trees preparatory to its 

 departure. On such occasions the individuals, often collected in great num- 

 bers, take up the time chiefly in pluming themselves, in which occupation 

 they continue for hours. 



I must conclude with assuring you that in my opinion, no difference 

 whatever exists between the Bank Swallow of America and that of Europe. 

 The birds from which I made the drawing for my plate were procured on 

 the banks of the Schuylkill river in 1824.

PLATE LI. 



On the afternoon of the 20th of October, 1819, I was walking along the 

 shores of a forest-margined lake, a few miles from Bayou Sara, in pursuit of 

 some Ibises, when I observed a flock of small Swallows bearing so great a 

 resemblance to our common Sand Martin, that I at first paid little attention 

 to them. The Ibises proving too wild to be approached, I relinquished the 

 pursuit, and being fatigued by a long day's exertion, I leaned against a tree, 

 and gazed on the Swallows, wishing that I could travel with as much ease 

 and rapidity as they, and thus return to my family as readily as they could
