[Lewis, August 25, 1804]
August the 25th on our return from the mound of sperits saw the first bats that we had observed since we began to ascend the Missouri
also saw on our return on the Creek that passes this mound about 2 M. distant S. a bird of heron kind as large as the Cormorant short tale long leggs of a colour on the back and wings deep copper brown with a shade of red. we could not kill it therefore I can not describe it more particularly.
