42 Lincoln, Nest of Leucosticte auslralis. [jg'J, 



It was in one of these latter that the nest was found, a short 

 cUff about forty feet in height, of Lincoln porphyry, protruding 

 through the upper edge of the schists and shales which occur just 

 below the granite cap. The face of this cliff had suffered consider- 

 ably from erosion, resulting in "chimneys" and cavities from a 

 few inches to several feet in diameter, and in one of the smaller of 

 these the nest was placed. The hole, forming the upper terminus 

 of a vertical crack, ran back twelve or fourteen inches and was 

 about forty inches from the base of the cliflf. 



The nest was discovered by flushing the female, which proved 

 to be extremely solicitous, returning repeatedly despite our pres- 

 ence, thus affording me an opportunity to photograph her at the 

 nest entrance. Both male and female were secured — C. M. N. H. 

 Nos. 4723 and 4728. 



The bulk of the nest was of dry grass and flower stems neatly 

 and compactly woven together with a considerable quantity of fine 

 moss, and lined with a fine yellow grass and a few feathers from 

 the bird's body, with one White-tailed Ptarmigan feather. It 

 rested well into the silt which covered the bottom of the hole, and 

 the cup was placed to one side, thus giving walls of unequal thick- 

 ness on two sides. This inequality did not, however, change the 

 general exterior shape wliich is practically round measuring 4.75" 

 in diameter with a depth over all of 3.00", while the cup measures 

 2.50" in diameter with a depth of l.GO". 



The eggs, three in number, are pure white, slightly glossy, un- 

 marked; ovate pyriform in shape; fresh; measurements in inches : 

 — .91 X .60; .95 X .63; .97 X .62.
