Common Nighthawk

Cptn. Lewis, June 30, 1805--There are a number of large bat or goatsucker here I killed one of them and found that there was no difference between them and those common to the U'States; I have not seen the leather winged bat for some time nor is there any of the small goatsuckers in this quarter of the country.  we have not the whip-poor-will either.  this last is by many persons in the U'States confounded with the large goat-sucker or night-hawk as it is called in the Eastern States, and are taken for the same bird.  it is true that there is a great resemblance but they are distinct species of the goatsucker.  here the one exists without the other.  the large goat sucker lays it's eggs in these open plains without the preperation of a nest.  we have found their eggs in several instances  they lay only two before they set nor do I believe that they raise more than one brood in a season; they have now just hatched their young.
