THIRD ANNUAL MEKTIN<; 87 



evident that she had a nest in the immediate vicinity and that I was 

 tod close to it for hei* ijcacc of mind. After about fifteen minutes of 

 xipward ga/Ang, at the expense of a nearly dislocated neck, I discovered 

 the frail nest far out on the lowest limb of an enormous pine. Having 

 a coil of rope with me, I secured one end to the camera and the other 

 to myself, and after a hard climb, manag-ed to reach the limb on which 

 the nest was situated, where a photograph of it was obtained from 

 the nearest possible point. It was fortunate, too, for it is the only 

 evidence that remains of the finding' of the eg"gs of the Louisiana 

 Tanager in Sioxix County, since the three eggs were almost upon the 

 point of hatching- and could not be .saved. 



The nest is constructed much like that of the Scarlet Tanager, being 

 perhaps a trifle bulkier, and haA-ing a base of pine needles, with the 

 main structure composed of rootlets. The eggs, too, resemble those 

 of the Scarlet Tanager, the chief difference in this set being- the heavier 

 and more evenly diifused mai'kings. 



Plumbeous Vireo (Vireo solitarius plumbcus). — This bii-d was only added 

 to our state list at a recent date, being found breeding for the first time 

 by Dr. Wolcott in Sioux County in 1900. On June 15 I started to ride to 

 Harrison and attempted to get out of the caiion by a side branch 

 Avhich I had never before explored, but I soon discovered the futility 

 of the attempt. I had just arrived at a point where the canon was 

 a mere cleft in the side of the ridg"e, with steep rocky sides, covered 

 farther up by pines and dense underbrush, and was turning my horse 

 in order to return, when I happened to glance upward, and there just 

 over my head hung a beautiful little cuiJ-shaped nest, adorned with 

 lichens and cobwebs, swinging from the forks of a drooping mountain 

 maple. I reached up and drew it gently down, and seeing that it con- 

 tained but one egg, I left it undisturbed. On the ISth we went up to 

 Indian Creek, and it was not until the 21st that I again visited the 

 nest, armed with shot-gun and camera. Two photographs were secured, 

 the nest with its four eggs, and both the birds, all of which are now 

 in the collection of the University. The nest was constructed of veg- 

 etable fibres, beautifully decorated with lichens and cobwebs, and lined 

 Avith the peculiar, round, grass-like material which all vireos use for 

 nest lining. The set consi.-sted of four dull white eggs, sparsely specked 

 and dotted around the larger end with burnt umber. They measure 

 respectively: 18.5x14, 19x14.5, 18x1.3, and 18.5x14 mm. 



Audubon's Warbler (Deiulroica auduhoiii). — This beautiful warbler, 

 resembling so much the Mja-tle Warbler, was found to be surprisingly 

 abundant among the pines of the canons, usually more abundant from 

 half way up the sides to the top. I think that we put in more actual 

 time hunting for nests of this bird than any other in the region, and 

 yet but one nest with eggs Avas found, by Mr. Cary on June 14. It was 

 a rainy, toggj morning, and we were exploring systematically some 

 cafions east of Warbonnet. While working up a side branch, we were
