ZOOLOGY. 
I never saw anything like a chimney swallow in any part of the country, and think that the 
Columbia must be the limit of migration to Vauxii. I think, however, I should have noticed 
it at Vancouver, if found there, in June and July, 1853. Dr. Kennerly has, however, since 
sent one from the Straits of Fuca, showing that it sometimes extends its migrations up to the 
49th parallel.—C. 
This bird was obtained by Dr. Townsend at Fort Vancouver, on the Columbia river, the 
point where Dr. Townsend obtained the greater part of his collection. I have never been able 
to procure a specimen of this bird, and therefore presume that it is of very rare occurrence.—S.

Sp. Ch. —Bristles without lateral filaments ; wing about 5£ inches ; top of the head hoary gray, with narrow transverse, not 
longitudinal hands. Tail nearly black on the terminal half, the extreme tip only (in the three outer feathers of each side) 
being white for nearly an inch. Length, 8 ; wing, 5.50 ; extent, 17.50 ; iris, brown ; hill and feet, gray. 
Hab. —High central plains to the Pacific coast. 
NuttalVs whippoorwill I have found only in the open country east of the Cascade mountains) 
where, in the summer of 1853, it was common near the Yakima river. The two specimens 
I obtained were killed with a whip in the daytime, being probably dazzled by the sunshine 
when started from the ground. Late in the evening I saw them flying near the ground and 
making a singular hollow sound as they sat on it, where I could not distinguish them in the 
twilight. I shot one in California as late as November 6. It would start close to my feet, fly 
short distances very irregularly, and alight on the ground. It was silent at that season.—C. 
This bird, well known as an inhabitant of the far west, is moderately abundant in the great 
arid interior of Washington and Oregon Territories. Along the coast I have never seen or 
heard one of the species, but east of the Cascade mountains, at Fort Dalles, on almost any fine 
night in spring and early in summer they can be heard uttering their cries. These closely 
resemble that of the Atlantic species, (A. vociferus ,) but are proportionately more feeble, and 
are not so incessantly kept up.—S.
