82 SYNONYMY OF SIALIA ARCT1CA 



near Fort Garland in 1873, nor at Santa Fe, N. Mex., in June 

 of 1874, where, however, the succeeding species was abundant. 

 About July 23, Inscription Rock, N. Mex., appeared to be a 

 favorite locality for the species, and large numbers of both old 

 and young were congregated together in the pinon and cedar 

 trees. From here southward they were frequently seen, com- 

 monly among the pines. At Cauip Apache, iu August, I 

 found them in large Hocks in the pine woods, and accompanied 

 by flocks of Warblers, Nuthatches and Titmice, to which they 

 seemed to act as leaders, the whole flock following their flight 

 from tree to tree. Jt apparently winters in the vicinity of 

 Camp Apache, being found here in quite large flocks in 

 November."
