166 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 tranverse, not 

 longitudinal bands. 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 ; bill and feet, gray. 

 Hob. High central plains to the Pacific coast. 



NutlaW s ivliippoorwill 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.
