foot of the Wahsatch Rauge, near Ogden. It is a peculiar bird, aud like 

 our eastern species, {leteria virens,) is always heard, but seldom seen. 

 They are shy, suspicious creatures, and although, when disturbed, they 

 flit about in a scolding, angry manner, they generally manage to keep 

 out of sight. You hear them in the bushes, imitating the mewing of a 

 cat, the shrill notes of the jay, sometimes singing like a cat-bird, and 

 yet, again, they sing sweetly in their own peculiar manner. They have 

 a strange habit of elevating themselves in the air to the height of thirty 

 or forty feet, then, poising themselves for a moment, they descend again 

 to the bushes; during their descent they jerk themselves about in the 

 air, at the same time uttering clear, ejaculated notes, which can be heard 

 for quite a distance, and are not altogether unpleasant to the ear. I 

 found the nest of this bird on the 15th of June ; it was on a scrub-oak 

 near a small stream ; was about four feet above the ground, and -con- 

 tained three young birds and one egg. The egg resembled, in size and 

 color, that of our eastern species, (J. virens.)

Audubon's warbler, though similar in most respects to our eastern yel- 

 low-rump warbler, fl). corouataj is easily distinguished from it by hav- 

 ing the chin and throat yelloiv instead of white. During the latter j^art 

 of September I saw several flocks of these birds on Snake Eiver ; they 

 appeared to be on their way south.

Yellow warblers were common at Ogden, as they were at all places 

 where there was a stream of water whose banks were lined with bushes. 

 I found the nestof this bird at Ogden — No. 24, (16294;) it was on a wil- 

 low, about three feet above the ground, and contained four fresh eggs.
