COEVIDyE — THE CROWS. 243 



White-necked Raven we have veiv litth; kii(}\vledge. IL was first described 

 by Lieutenant Couch, in 1854, from specimens obtained by him at Cliarco 

 Escondido, Mexico, in May, 1853. Other specimens were afterwards pro- 

 cured by Dr. Kennerly, at Janos, Mexico, in 1855, and by Mr. Dresser at 

 Eagle Pass, Texas, in March, 1SG4. The latter gives no notes as to its 

 habits. 



Dr. Kennerly 's note in regard to it is that it was not very common, and 

 when seen was generally associated with t\u'. larger species of Eaven. Lieu- 

 tenant Couch merely mentions it as found in .small nundjers in Eastern 

 Tamaulipas, generally near ranches. 



^Ir. J. 11. Clark writes that this species does not seem to possess the 

 running nr wariness of its congeners. It was met with, in the greatest 

 abundance, about watering-places. It was not found habitually in great 

 flocks, though at the head of the Linipia many were congregated and flying 

 about the face of an immense rocky mountain wall, wiiere they were 

 probably nesting. Their note he describes as coarse, and less shrill than 

 that of the common Crow. He met with the supposed nest in an arbo- 

 rescent cactus. ■ 



Dr. Cones does not appear to have met with this species in Arizona, but 

 Lieutenant Bendire writes to Professor liaird from Tucson, April 12, 1872, 

 that it is the most cummon Crow or Itaven there. This he discovered 

 accidentally, finding that three fourths of the Havens he shot proved to be 

 of this species ; the otliers were the Colorado race of the Eaven. Speci- 

 mens of this Crow were obtained at Fort Buchanan by Dr. Irwin, at Pecos 

 Eiver by Dr. Anderson, and in tlie Indian Territory by Mr. iMcCarthy. 



An egg of this species, from Trout Creek, Texas, obtained June 20 by 

 Charles S. McCarthy, measures 1.75 inches in length l)y 1.25 in breadth. 

 The ground-color is a light grayish-green, and is pretty uniformly marlced 

 with fine dottings iif mingled purple and brown.
