near Bijoux hills. Other parties have obtained it from Independence, on the Missouri 
river. Its range is Eastern United States to the slopes of the Rocky mountains. 
ANTROSTOMUS VOCIFERUS, Bonap. 
WHIP-PooR-wit. Baird, General Report on Birds, p. 148. 
Though no specimens of the above species were obtained by us, we have heard its well- 
known notes every spring in ascending the Missouri, near the mouth of Big Sioux river. 
I do not think that it is found on the Upper Missouri. 
Antrostomus NuttTALui, Cassin. 
Poor-wiLu. Baird, General Report on Birds, p. 149. 
Though rarely seen, this bird seems to be distributed throughout the Upper Missouri 
country. It is usually found on the Sage plains, and rises up quickly from the ground 
before the traveller, flies a short distance with great rapidity, and then settles down again 
in some concealed place. I think I have never seen more than six or eight individuals in 
a single season, but its familiar notes “ poor-will” are often heard about dusk, and continue 
until late at night. It is found on the high central plains to the Pacifie. 
CHORDEILES POPETUE, Baird. 
Nieut Hawk. Baird, General Report on Birds, p. 151. 
Very abundant throughout the Northwest. 
CERYLE ALCYON, Boie. 
BELTED KINGFISHER. Baird, General Report on Birds, p. 159. 
This bird, though not common, is seen occasionally along all the streams of the North- 
west. It usually makes its appearance about the first of May. It is universally distri- 
buted over North America. 
TYRANNUS CAROLINENSIS, Baird. 
Kine Birp; Bee Brrp. Baird, General Report on Birds, p. 171. 
Very abundant, especially along the Lower Missouri, but found more or less numerous 
throughout the Northwest. It ranges over Eastern North America to the Rocky moun- 
tains. 
TYRANNUS VERTICALIS, Say. 
Arkansas Frycatcuer. Baird, General Report on Birds, p. 178. 
The two species of the genus Tyrannus which occur in the Northwest, seem to have 
habits very much alike, and are often found together, so much so that I at first, with my 
slight knowledge of ornithology, regarded them as male and female of the same species. 
The yellow-breasted Tyrannus does not make its appearance, however, until we reach a
