1915 BIRDS OF CALIFORNIA 135 
Status—Common summer visitant to semi-arid Transition, breeding chiefly 
in this zone on desert ranges and along the eastern slope of the Sierras from the 
Warner Mountains, Modoc County (Mus. Vert. Zool.) south to the San Jacinto 
Mountains (J. Grinnell and Swarth, Univ. Calif. Publ. Zool., x, 1918, p. 283). 
Breeds locally on the western slope of the Sierras, especially southerly ; also west 
in the mountains of southern California to Mount Pinos (J. Grinnell, Auk, xx, 
1905, p. 389). Occurs in migration widely east of the Sierras, and sparingly 
west of the Sierras. Recorded west to Mount Shasta (Feilner, Ann. Rep. Smiths. 
Inst., 1865, p. 426), head of Bear Creek, Trinity County (Mus. Vert. Zool.), 
South Yolla Bolly Mountain (Ferry, Condor, x, 1908, p. 43), Mount Sanhedrin 
(Stone, Proc. Acad. Nat. Sci. Phila., 1904, p. 583), Clear Lake, Lake County 
(Baird, Brewer, and Ridgway, Hist. N. Amer. Bds., m1, 1874, p. 517), San Fran- 
cisco (Emerson, Orn. & Ool., rx, 1884, p. 93), and San Jose (Van Denburgh, 
Proe. Amer. Philos. Soc., xxxvi, 1899, p. 174). Winters rarely in the San 
Diegan district: Santa Ana River bottom near San Bernardino (Thurber, Auk, 
xi, 1896, p. 265) ; San Diego (J. G. Cooper, Orn. Calif., 1, 1870, p. 248). 
408 (595) Zamelodia ludoviciana (Linnaeus) 
ROSE-BREASTED GROSBEAK 
Status—Rare sporadic visitant: Several individuals obtained by C. H. Gil- 
bert and party at Myer’s, Humboldt County, July 1, 1897 (Mclain, Auk, xv, 
1898, p. 190) ; immature male taken by M. F. Gilman at Palm Springs, Riverside 
County, September 10, 1897 (J. Grinnell, Pac. Coast Avif. no. 3, 1902, p. 59). 
Both records verified: basis of the former in collection of Stanford University, 
the latter in Grinnell collection. Sequoia and General Grant National Parks, 
Tulare County, ‘‘very rare’’ (Fry, U. S. Dept. Interior, General Information Re- 
garding Sequoia and General Grant National Parks, Season of 1912, p. 14). 
409 (596, part) Zamelodia melanocephala capitalis (Baird) 
Pactric BLACK-HEADED GROSBEAK 
Synonyms—Guiraca melanocephala; Coccoborus melanocephalus; Gonia- 
phea melanocephala; Hedymeles melanocephalus; Habia melanocephala; Zame- 
lodia melanocephala, part; Zamelodia melanocephala microrhyncha; Hedymeles 
melanocephalus var. capitalis. 
Status—Abundant summer visitant almost throughout the state, both east 
and west of the Sierras. Breeds chiefly in Upper Sonoran and Transition zones, 
preferably in riparian or deciduous growths of trees; but otherwise the species 
oceurs indiscriminately without regard to relative humidity of climate; for ex- 
ample it is recorded from Humboldt Bay and the Panamint Mountains. The 
focus of abundance is in the willow bottoms of the interior valleys. Occurs most 
widely in migration. Reported away from the mainland only from Santa Cruz 
Island (J. Mailliard, Bull. Cooper Orn. Club, 1, 1899, p. 45), and the Farallones 
(W. E. Bryant, Proc. Calif. Acad. Sci., 2nd ser., 1, 1888, p. 47).
