of the junco. A nest of Shufeldt's Jimco was found on July 

 9, in the woods near the base of MacDougal Peak. It was on 

 the side of a small moss-covered mound, which had been formed 

 by the uprooting of a tree in other years. The nest 

 was in a recess, and was made of coarse weed-stems 

 and lined with fine light gi-asses. It was four inches across and 

 two inches high after removal from the site. The cavity meas- 

 ured two and one-half inches in diameter, and one and one- 

 fourth inches in depth. Its complement was four fresh eggs, 

 whicli were greenish-white, marked with reddish-brown, the 

 larger end as usual having the greater amount of markings. 



While at Sin-yale-a-min Lake, a number of used nests were 

 examined, the work of the black-headed jay, cyanocitta stelleri 

 annedens (Baird). They were found in small firs, invariably 

 along the streams, and generally about twelve feet from the 

 ground, on horizontal branches beside the main stem. The 

 chosen site was usually about three-fourths the height of the 

 tree. They were made of an outer framew^ork of coarse twigs, 

 and were about eight inches across in exterior measurement, 

 and five inches high. The outer wall was made of muddy moss 

 and coarse stems, the lining being of coarse brown rootlets. The 

 cavity averaged four and three- fourths inches in diameter, and 

 three inches deep. 



On June 28, I found a nest of the black-headed jay near a 

 bridge over a small stream where we stopped for lunch. The 

 nest was eighteen feet from the ground, in a stout upright fork 

 of the main stem, which leaned over the water. It was made 

 as described in the foregoing paragraph, having an outer frame- 

 work of coarse twigs, walls of mud about a half-inch thick, an 

 inner wall of coarse black rootlets, and a bedding of finer 

 rootlets. There were four eggs, on which the female was sit- 

 ting. She was secured for identification, and later, when the 

 male came near, with a mouthful of grasshoppers, he was also 

 taken. The eggs were quite advanced in incubation. They 

 were light green in color, irregularly spotted with dark-brown. 

 About twenty feet from the tree containing this nest was an- 

 other with an old nest similar in construction, situated in a 

 small fir as previously described. It is likely that the nest 

 with eggs was a second nesting of this pair of jays; if such 

 is the case, it will account for the late date of nidification, as 

 the usual season of this jay had apparently closed in the neigh- 

 borhood.
