The Fox Sparrows 



demure, so even-tempered, and so kindly a bird-person, with such a 

 preserving air of gentle breeding, I have not often seen. It was an hour 

 to be long remembered. 



No. 65i Warner Mountains Fox Sparrow 



A. 0. U. No. 585c, part. Passerella iliaca fulva Swarth. 



Description. — Very similar to P. i. schistacea, but bill larger and differently 

 shaped, with notable increase of basal dimensions: culmen 12. 1 (.476); depth of bill 

 at base 1 1. 1 (.437), width at base 9.5 (.374); tail longer than wing, 82.2 (3.236), as 

 against 80 (3. 15); other dimensions about as in schistacea. 



Range of P. i. fulva. — As at present defined is wholly included within the limits 

 of California. Breeds in the Warner Mountains, Modoc County. Winter range 

 not yet defined, but a specimen (M. C. O. coll.) taken at Santa Barbara, Jan. 11, 

 1913, is referred by Swarth to this form. 



Authorities. — Swarth, Proc. Biol. Soc. Wash., vol. xxxi., 1918, p. 162 (Sugar 

 Hill, Modoc Co.; orig. desc); Univ. Calif. Pub. Zool., vol. xxi., 1920, p. 158, figs, 

 (occurrence in Calif., distr., desc, crit.); Bendire {Passerella iliaca schistacea, part), 

 Auk, vol. vi., 1889, p. 113 (eastern Oregon; nest and eggs, habits, etc.). 



No. 65j Thick-billed Fox Sparrow 



A. O. U. No. 585c, part. Passerella iliaca megarhyncha Baird. 



Description. — Similar to P. i. fulva, but browner, amounting to an olivaceous 

 cast over upper plumage; bill much stouter, intermediate in this regard, as in brownness 

 of plumage, between fulva and brevicanda. 



Range of P. i. megarhyncha. — Breeding range undefined; may prove to be the 

 breeding bird of the Cascade system in Oregon and Washington, or at least of the south- 

 ern portion of that system. Winters commonly in the San Diegan district north at 

 least to Fort Tejon, Kern County, and west to Santa Barbara (M. C. O. coll.). 



Authorities. — Baird, Rep. Pac. R. R. Surv., vol. ix., 1858, p. 490 (Passerella 

 schistacea, part); idem, p. 925 (Passerella megarhynchus, Ft. Tejon, orig. desc.) ; Swarth, 

 Univ. Calif. Pub. Zool., vol. xxi., 1920, p. 161, figs, (occurrence in Calif., distr., desc, 

 crit.). 



No. 65k Yolla Bolly Fox Sparrow 



A. O. U. No. 585c, part. Passerella iliaca brevicauda Mailliard. 



Description. — Similar to P. i. megarhyncha, but darker and browner with fur- 

 ther increase of bill dimensions, comparable in this regard to P. i. stephensi, from which, 

 however, it differs markedly in color-pattern and in shape of bill, which is constricted 

 distally. Measurements: wing 83 (3.27); tail 84 (3.31); culmen 13.3 (.52), depth 

 14. 1 (.55), width at base 11. 8 (.465); tarsus 23.8 (.937). 



Range (Possibly wholly included within California). — Breeds in the northern 

 interior and coastal ranges (the Trinities, Yolla Bollies, etc.) of California; winters 

 from Marin County south (at least) to Santa Barbara. 



Authorities. — Oberholser (Passerella iliaca stephensi), Proc. U. S. Nat. Mus., 

 vol. xxii., 1900, p. 233; /. Mailliard, Condor, vol. iv., 1912, p. 63; ibid., vol. xx., 1918,
