BIRDS. 29 



48. POOSPIZA BELLII, Sclater, (p. 470.) 



6336. Colorado river, California, December 15, 1853. Kennerly and MoUhausen. 



This little bird was found in the month of December along the Little Colorado river, wherever 

 the weeds and bushes were thick. It was never observed very far from the water, and its food 

 at this season seemed to consist of the seeds of various kinds of weeds. In its motions it was 

 quick ; and when made to fly, its flight was short, rapid, and near the earth. 



49. SPIZELLA MONTICOLA, Baird, (p. 472.)— Tree Sparrow. 



6354, 6355. Little Colorado river, New Mexico, December 18, 20, 1853. (39.) Kennerly 

 and Mollhausen. 



Along the Little Colorado river, in the month of December, we found this little sparrow quite 

 abundant, feeding upon the seeds of the grapes and weeds that grow along the valley. 



50. SPIZELLA BREWERI, Cass in, (p. 475.)— Brewer's Sparrow. 



6358. Camp 127. Bill Williams' Fork, New Mexico, February 26, 1854. (174.) Ken- 

 nerly and Mollhausen. 



We found this bird throughout New Mexico, from the Rio Grande to the Great Colorado 

 along the difterent streams, where it fed upon the seeds of various kinds of weeds. 



51. MELOSPIZA FALLAX, Baird, (p. 481.) 



Plate XXVII, Fig. 2. 



Pueblo creek. New Mexico, January 22, 1854. (51.) First described from this specimen. 



We observed this little bird only along Pueblo creek, in the month of January. It did not 

 confine itself to the open valley, but was often seen among the thick bushes that margined the 

 creek far up in the Aztec mountains, where the snow covered the ground. In its habits it very 

 closely resembles the Poospiza bellii, being very restless and rapid in its motions, accompanying- 

 them with a short chirp, feeding upon the seeds of the weeds that remained uncovered by the 

 snow. Its flight was also rapid and near the earth. Being very shy, I found it difiicult to 

 procure many specimens. 



52. MELOSPIZA LINCOLNII, Baird, (p. 482.)— Lincoln's Finch. 



6325. Camp 131, New Mexico, February, 1854. (100.) K. & M. 



This bird we found in the month of February, from the Big Sandy to the Great Colorado 

 river. It confined itself to the thick bushes along the stream, and when seen was generally 

 busily hopping from twig to twig in search of food. When made to fly, its flight was noticed 

 to be very rapid and near the earth.
