COKVin.E — THE CROWS. 24.'> 



Wliite-iieclvefl leaven we liave voiv little kii()\vle(l«;e. It was tirst desi'iihtd 

 by J JiMiteiiant ('oiu'li, in lsr»4, IVoni .specinuMis ulitaiiied by him at Cliaico 

 Kscoiuliilo, Mexico, in May, IH't'S. Other specimens were at'terwanls i>ri)- 

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

 >^igle Pass, Texas, in March, 1804. The latter yives* nu 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 associateil with tiie larger si)ecies of JIaven. Lieu- 

 tenant Couch merely mentions it as found in small numbers in Eastern 

 Tamaulipas, geneiiiUy near ranches. 



iVIr. J. H. Clark writes that this species does not seem to ])ossess the 

 cunning or wariness of its congeners. It was met with, in the greatest 

 abun<lance, about watering-places. It was not found habitually in great 

 flocks, though at the head of the Limpia many were congregated and Hying 

 about the face of an immense rocky mountain wall, where they W(Me 

 ])robably nesting. Their note he describes as coarse, and less shrill than 

 that of the common Crow. He met with the su])posed nest in an arl>o- 

 rescent cactus. 



Dr. Cones dotis not appear to have met with this sj)ecies in Arizona, but 

 Lieutenant Bendire writes to Profes.sor Baird from Tucson, A])ril 12, 1S72, 

 that it is the most common Crow or Haver there. This he discovered 

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

 of this species ; the others were the Colorado race of the IJaven. Sj)e('i- 

 mens of this Crow were obtained at Fort I>uclianan by Dr. Irwin, at Pecos 

 liiver by Dr. Andei^son, and in the Indian Territory by ^Ir. McCarthy. 



An i.'^^*r of this species, from Trout Creek, Texas, obtained June 20 by 

 Charles S. McCarthy, measures 1.75 inches in leniith by 1.25 in breadth. 

 The ground-color is a light grayish-green, and is pretty imifonnly marked 

 with tine dottiugs of mingled purple and brown.
