Cassin's Kingbird, at the nesting season, barely exceeds the upper limit of the Lower Sonoran faunal zone; and it is not even mentioned in the exhaustive reports on the San Jacinto and San Bernardino mountain regions. It is apparently of very irregular dis- tribution over the two California deserts, and in the lowlands of the San Diego-Santa Bar- bara region. I have found what I believe to be its local center of abundance in the sparse- ly timbered valley of the Estrella, in northern San Luis Obispo Coun- ty, and in the connecting tributaries. Here its close and all but invari- able association with T. verticalis is worthy of special notice. In this region of scattering oak trees and of stream beds lined with cottonwoods, both birds are exceedingly com- mon. As surely as a pair of oak trees boast some degree of isolation from their fellows, one will be occupied by a pair of Cassin Kingbirds and the other by a pair of Westerns. Or if the trees are only members of a ser- ies, next door neighbors will be. Taken in San Luis Obispo County Photo by the A uihor 860 CASSIN KINGBIRD IN LIVE OAK 1 Life Histories, Vol. II., p. 250.
