Dr. Cooper found a nest of this species, but without eggs, built in a yucca, and similar to that of _H. redivivus_. In his Report on the Birds of California, Dr. Cooper speaks of finding this bird common on the deserts, along the route between the Colorado Valley, wherever there was a thicket of low bushes surrounded by sand-hills. Its notes, habits, and general appearance were like those of _H. redivivus_. Harporhynchus redivivus, CABAN. CALIFORNIA THRASHER. _Harpes rediviva_, GAMBEL, Pr. A. N. S.

The California Thrasher appears to have a somewhat restricted distribution, being confined to the coast region of California, where, however, it is quite abundant. It was first met with by Dr. Gambel, near Monterey. The specimens were obtained on the ground where they were searching for coleopterous insects. Dr. Heermann afterwards found this bird abundant in the southern part of California. It was difficult of approach, diving into the thick bushes, running some distance on the ground, and becoming afterwards unapproachable. He speaks of its song as a flood of melody equalled only by the song of the Mocking-Bird (_Mimus polyglottus_). Colonel McCall also describes its song as of exquisite sweetness, “placing it almost beyond rivalry among the countless songsters that enliven the woods of America.” He also states that it is as retiring and simple in its manners as it is brilliant in song.
