Chorcleiles popetue. — (Yieill) . 
Night Hawk.—Bull Bat.—Musquito Hawk.—Goatsucker. I have met 
with only one well marked species from the coast to the summit of the Rocky 
Mountains. They arrive at "Vancouver Island and along the coast in May, and 
at Colville in June. On the 7th of June I observed a great number of these goat¬ 
suckers in company with the green-backed swallow, and what I imagined to be 
the black swift, but as they never came within range I could not determine the 
matter. I succeeded in getting three swallows and one goatsucker, a male, its 
stomach was gorged wiih winged ants;—a flight of these insects had, I imagined, 
attracted all these birds. 
When flying high this goatsucker makes a curious kind of chirp, hence the name 
by which they are known throughout Oregon and California as Pisic, and when 
they swoop down as they constantly do from a great height, they make a loud 
booming noise almost like a roar , or the twang of a large metal harp string, whence 
I suppose comes the other name of Bull hat. 
I have noticed them 7000 ft. above the sea level, both on the Cascades and the 
Rocky Mountains. 
They lav two eggs in July on the bare ground. 
They have a curious habit of pitching on the ground just as it is getting dark, 
and running along like a sandpiper, chasing moths and small insects. I have often 
seen them pitch close to my feet. 
Tyrannus carolinensis .— (Baird). 
King-Bird.—Bee Martin. Common from the coast to the summit of the 
Rocky Mountains, arrives at Vancouver Island, and along the coast about the end 
of March, and at Colville in the beginning of April, begins building in May. 
Leaves Colville again in September, frequents valleys and open timbered lands. I 
have never seen it more than 2000 feet above the sea level. Specimens brought 
home from various spots on the line. 
Tyrannus verticalis. — (Say). 
Arkansas Flycatcher. Common from the coast to the west slope of the 
Rocky Mountains; habits valleys, open prairies and banks of streams, arrives in 
April and leaves again in September; builds in May, and does not reach a greater 
altitude than about 2000 ft. above the sea level. 
Specimens brought home from different localities along the line, and from 
Vancouver Island. 
Contojous borealis .— (Baird). 
Olive Sided Flycatcher. The only specimens I obtained were shot at 
Sumass prairie in June; it makes its first appearance in May, and leaves again in 
September. 
It usually sits on the top of a dead tree, or on the end of a dead branch, dashing 
off after any insect that may chance to pass, and then returning again to its watch 
tower. I did not find its nest; I never saw this Flycatcher east of the Cascades. 
Turdus (Planesticus) migratorius — (Linn.) 
Robin. Abundant everywhere from the coast to the very summit of the Rocky 
Mountains. Arrives in flocks early in April, even before the snow is off the 
ground: it is about the first harbinger of the coming summer, leaves again in 
September and October. 
Chooses all sorts of places for its nest. Very abundant on Vancouver Island.
