PASSERCULUS SAVANNA, W i 1 s .—Savanna Finch. 



Fringilla savana, Wii.s. Am Orn. vol. IV, p 72, pi. 34, fig. 4. — Nutt. Orn. vol. I, p. 489. — Add. B. of A. Fol. pi. 109. 

 Emberiza savana, Aud. Oet. vol. Ill, p. 68, pi. 160. 



Abundant. 



PASSERCULUS ALAUDINUS, Bonap. 



Passerculus alaadinus, Bonap. Comptes Rend. vol. XXXVII, p. 918, Dec. 1853. 



This bird I shot on the swampy borders of a pond near the barracks at Benicia. Its habits, 

 from the limited observations afforded me, I deem the same as those of our sea side finch, 

 (Ammodramus maritivius.) When flushed from its covert of rushes and rank grass it flew but 

 a short distance and settled down, concealing itself so quickly that unless promj^tly shot while 

 on the wing it could not be captured. 



PEUCAEA LINCOLNII, Aud .—Lincoln's Finch. 



Peiicaea Uncolnii, Aro. B. of A. Oct. vol. Ill, p. 116, pi. 177. 

 Fringilla Uncolnii, Aud. Fol. pi. 193. 

 Mdospiza Uncolnii, Baird, Gen. Rep. IX, 482. 



I have obtained this species not unfrequently both in northern California and tlie Tejon 

 valley, and on all occasions found it in company with flocks of sparrows, composed of several 

 difierent varieties. 



COTURNICULUS PASSERINUS, Wi Is .—Yellow-winged Finch. 



Emberiza passerina. Add, B. of A. Oct. vol. Ill, p. 73, pi. 162. 



FringiUa passerina, Add. B. of A. Fol. pi. 130. — Wils. Am. Orn. vol. Ill, p. 76, pi. 24, fig. 5. 



Abundant. 



AMMODRAMUS RUFICEPS, Cassin .—Brown-headed Finch. 



Ammodramus ruficeps, Cassin, 111. B. of Tex. and Cal. p. 135, pi. 20. — 1b. Proceed. Ac. Nat. Sc. Phil. vol. VI, p. 184. 

 Peucaea ruficeps, Baird, Gen. Rep. IX, 486. 



In the fall of 1851 I shot, on the Cosumnes river, but one specimen of this bird, from among 

 a large flock of sparrows, but in 1852, during the spring, in the mountains near the Calaveras 

 river, I found it quite abundant. It flew then in pairs, picking grass seeds from the ground, 

 and when started never extended its flight beyond a few yards. Its notes in character resemble 

 the ditty of our chipi^ing sparrow, {Spizella socialis. ) 



LINARIA PINUS, Wilson .—Pine Linnet. 



Linaria pinus. Add. B. of A. Oct. vol. Ill, p. 125, pi. 180. 



Fiingilla pinus, Add. Fol. pi. 180.— Wils. Am. Orn. vol. II, p. 133, pi. 17, fig. 1.— Ndtt. Orn. vol. I, p. 51 1. 



Cardudis pinus, DeKay's N. H. of N. Y. vol. I, p. 167, pi. 59, fig. 136. 



Chrysomitris pinus, Baied, Gen. Rep. IX, 4'25. 



Found in the mountainous districts during the winter season, feeding on the young buds of 

 plants or extracting the seeds from the pine cone, to which it often hangs with its back down- 

 wards while thus occupied.
