Nuttall's ^VllippoorwiU is readily distinguished from the other North Ameri- 

 can species by tlie transverse, not longittidiual, lines on the toj) of head, the 

 narrow wliite tip of tail on both webs, and the inferior size, as well as by 

 numerous other points of difference. 



H.\BITS. This species was first described by Mr. Andubon from a speci- 

 men obtained near tlte Eocky Mountains, but with no information in regard 

 to any peculiarities of habit. From Mr. Nuttall we learn that tliese birds 

 were first observed by him on the 10th of June, amidst the nalced granite 

 hills of the sources of the Upper Platte Eiver, called Sweet-Water. It was 

 about twilight, and from the clefts of the rocks they were uttering at inter- 

 vals a low wailing cry, in the manner of the Whippoorwill, and sounding 

 like the cry of the young of that species, or jk-cu. Afterwards, on the 7th 

 of August, when encamped on the higli ravine of the insulated mountains 

 so conspicuous from Lewis Eiver, called the Three Buttes, this bird was 

 again obser\-ed, as it flew from under a stone near the summit of the moun- 

 tain. It flew about luxwking for insects near tlieir elevated camp, for two 

 or three hours, but was now silent. On the 1(3 tli of June, near the banks 

 of the Sandy Eiver of the Colorado, Mr. Nuttall again heard its nocturnal 

 cry, which he says sounded like pevai.
