Toxostoma rediviva, Gambel, Journ. Acad. N. S. Phil. 2d series, vol. I, p. 42. 
Harpes redivivus, Gamb. Proceed. Acad. N. S. Phil. vol. II, p. 264 
Harporhynchus redioivus , Baird, Gen. Rep. IX, 349. 
Abundant, not only having procured it in northern California, hut also as far south as Texas, 
on the borders of the Rio Grande. Shy and wild in its habits, when startled it flies low 
some distance, and plunging into a thicket alights, runs on the ground, and so conceals itself 
that it is not again easily found. Its notes are equal in harmony to those of our mocking bird, 
and among the miners it is well known as the California mocking bird. It incubates in the 
country, hut the only nest I found, composed externally of coarse twigs and lined with fine roots, 
contained young, it then being the month of July. 
TURDUS MIGRATORIUS, L i n n .—The Robin. 
Tardus migratorius, Aud B. of A. Oct. vol. Ill, p. 14, pi. 142.— Nutt. Ora. vol. I, p. 339.— Wils. Am. Ora. vol. I, 
p. 35, pi. 2, fig. 1. 
Abundant, hut only appearing in the mining regions of California during the winter season. 
Several flocks of these birds were observed at Fort Yuma in the month of December. 
TURDUS NAEV1US, Gmel .—The Varied Thrush.

Orpheus meruloides, Rich. & Sw. F. Bor. Am. part II, p. 1S7, pi. 33. 
Abundant, being found in the mountainous districts in large flocks, frequenting the moist 
hill sides in search of food. It does not incubate in the country, but migrates north in early 
spring. 
TURDUS NANUS, Aud.—Dwarf Thrush. 
Tardus nanus, Aud. B. of A. Oct. vol. Ill, p. 32, pi. 147. 
Abundant. I found this species breeding in the stunted oaks covering the sand hills around 
San Francisco.

Anthus ludovicianus, DeIvay, N. Hist. N. Y. part I, p. 76, pi. 64, fig. 99.— Aud. B. of A. Oct. vol. Ill, p. 40, pi. 150.

Abundant.

Abundant. Congregating with the two preceding species, they form together large flocks, 
covering the plains during the fall season, engaged in gleaning the seeds of grasses and small
