ZOOLOGY-BIRDS. 
BUBO VIRGINIANUS, Gmel.—Great Horned Owl. 
Bubo virginianus, Nutt. Ora. vol. I, p. 124 — DeKay. N. Hist. N. Y part I, p. 24, pi. 10, fig. 22. —Aud. B of A. Oct. 
vol. I, p. 143, pi. 39 .—Cassin, Gen. Rep. IX, 49. 
Slrix virginiana, Aud. Fol. pi. 61.—Wins. Am. Ornith. vol. VI, p. 52, pi. 50, fig. 1. 
While encamped in the mountains bordering the Tejon valley, I occasionally heard the cry 
of this species at dusk and during the night. In 1849 it was very abundant around Sacramento 
City, but is now rare in that locality, from the same causes which have also driven almost 
entirely away the Slrix pratincola. 
SCOPS ASIO, Linn .—The Little Screech Owl. 
Slrix asio, Nutt. Orn. vol. I, p. 120 .—Aud. B. of A. Fol. pi. 97 .—Wils. Am. Orn. vol. V, p. 83, pi. 42, fig. 1. 
Slrix naevia, Wits. vol. Ill, p. 17, pi. 19, fig. 1. 
Bubo asio, Aud. B. of A. Oct. vol. I, p. 147, pi. 40.— DeKay, N. Hist. N. Y. part I, p. 25, pi. 12, figs. 25 & 26. 
This species is not rare though not easily procured, inasmuch as it leaves its covert only at 
night in search of prey. 
ANTROSTOMUS NUTTALLI, Aud.—Nuttall’s Whip-poor-will. 
Caprimulgus nultallii, Aud. B. of A. Oct. vol. VII, p. 350, pi. 495. 
Antrostomus nultalli, Baird, Gen. Rep. IX, 149. 
I saw two specimens of this bird in the mountains bordering the Tejon valley. They started 
from the ground, flew a few yards, and alighted almost immediately, as if blinded by the too 
glaring light of the sun. I shot one to assure myself of the species, but being on a grizzly bear 
hunt, with only my rifle in hand, it was so mutilated as to be worthless as a specimen. Dr. 
Milhau, U. S. A, at Fort Yuma, informed me of a small species of Caprimulgus very abundant 
around the fort during the spring and summer seasons. I procured none, being there during 
the winter, and am unable to say if it be the present species or not. 
CHORDEILES POPETUE, Y i e i 11 o t .—Night Hawk. 
Chordeiles virginianus, Aud. B. of A. Oct. vol. I, p. 159, pi. 43. 
Caprimulgus virginianus, Nutt. Orn. vol. I, p. 619 .—Aud. B. of A. Fol. pi. 147. 
Caprimulgus americanus, Wils. Am. Orn. vol. V. p. 65, pi. 40, fig. 1—2. 
Caprimulgus popetue, Vieill. Ois. Am. Sept. vol. I, p. 56, pi. 24. 
Chordeiles popetue, Baird, Gen. Rep. IX, 151. 
Not rare during the spring and summer seasons. I met with this species quite abundantly 
in Texas. 
PANYPTILA MELANOLEUCA, B a i r d .-White-bellied Swift. 
Cypselus melanoleucus, Baird, Proceed. Ac. N. Sc. Phil. vol. VII, p. 118 .—Ib. Gen. Rep. IX, 141. 
I saw this bird on several occasions, but always flying so high as to be beyond or on the 
extreme limit of gun-shot range, and was not fortunate enough to procure one. 
PROGNE PURPUREA, Linn .—The Purple Martin. 
Ilirundo purpurea, Aud. B. of A. Oct. vol. I, p. 170, pi. 45.— Ib. Fol. pi. 22 .—Nutt. Orn. vol. I, p. 598 .—Wils. Am. 
Orn. vol. V, p. 58, pi. 39, fig. 1—2. 
Yery abundant, breeding in large numbers in the hollow trees which are still left standing in 
the city of Sacramento.
