About 15 Swamp Sparrows were found on the coastal slope, with another at C.L. 11 Dec–9 Jan (SLS) and at least 3 at S.E.S.S. during the period. Two-thirds of the 68 coastal slope White-throated Sparrows were in the two n. counties, San Luis Obispo and Santa Barbara; 3 more were in the Kern River drainage of Kern 17 Dec–21 Jan, and 7 others were on the des - erts.
