ZOOLOGY — BIRDS. 57 



SBLASPHORUS RUFUS, G m e 1 .— Nootka Sound Humming Bird. 



Sdasphamx rufus, Gould's Monog. of the Trochil. part III.— Anc. B. of A. Oct. vol. IV, p. 200, pi. 254. — Baihd, Gen. 

 Kep. IX, 134. 



This diminutive species migrates to the higher northern latitudes, although some few pairs 

 breed every year in the neighborhood of San Francisco, where I observed them during the 

 whole summer, but was unable to discover their nests. I also noticed in this same locality the 

 white-crownad finch {Z. atricapilla) and the chesnut-backed tit, {Parus rufescens,) which birds 

 I have seen breeding in no other part of the country, the masses migrating north, while 

 probably these few stragglers, arriving late in the season, stop at this point. The cold sea 

 winds, which blow strongly every afternoon during the summer at San Francisco, give to this 

 locality very much the climate we might expect in higher latitudes. 



CEEYLE ALCYON, Linn .—Belted Kingfisher. 



Alcedo alcyon, Aud. B. of A. Oct. vol. IV, p. 205, pL 255.— Wils. Am. Orn. vol. Ill, p. 59, pi. 23, fig. 1.— Ndtt, Oru. 



vol. I, p. 594. 

 Ceryk alcyon, Baird, Gen. Rep- IX, 158. 



Abundant on all the principal lakes and water courses. 



PIOUS HAERISII, Aud.— Harris' Woodpecker. 



Pima harridi. Add. B. of A. Oct. vol. IV, p. 242, pi. 261.— Baird, Gen. Rep. IX, 87. 

 Occasionally observed during the survey, but a somewhat rare species, though procured in 

 northern California and at Tejon Pass. Its clear trumpet-like notes, uttered as it climbs the 

 trees, betrays its locality and it is then easily shot. 



PIOUS MERIDIONALIS, Swains .—Little Georgian Woodpecker. 



Picus meridionalis, Rich. & Sw. F. Bor. Am. vol. II, p. 308. 

 Fiem gairdnerii, Aud. B. of A, Oct. vol. IV, p. 252. 



Neither common or especially rare. I obtained several specimens in the mountains of northern 

 California. 



PICUS NUTTALLI, Gamb .— Nuttall's Woodpecker. 



Picas nuilallii, Gambel, Proceed. Ac. N. So- Phil. vol. I, p. 259. (1841. ) 



Picus scalaris, (Wagl.) Gambel, Jour. Ac. N. So. Phil. vol. 1, 2d series, p. 55, pi. 9, figs. 2 & 3. (Not of Wagler.) 



Occasionally found in the same localities as the preceding species, but much more abundant in 

 the valleys. 



PICUS SCALARIS, W a g 1 e r .—Barred Woodpecker. 



Picas scalaris, Wagler, Isis, 1829, p. 511. — Baird, Gen. Rep. IX, 94. 



I procured this bird first at Yallecitta, but found it abounding in the woods about Fort Yuma. 

 This species is new to the California fauna though frequently seen in Texas, several expeditions 

 sent having collected it. 



PICUS RUBER, G m e 1 .—Red-breasted Woodpecker. 



Picas ruber, Gk. Syst. Nat. vol. I, p. 429.— Lath. Ind. Orn. vol. I, p. 228.— Add. B. of A. Oct. vol. IV, p. 361, pi. 



266. 

 Sphyropieia ruber, Baird, Gen. Rep. IX, 104.
