 Harporhynchus redivivus, BAIRD, Gen. Rep. IX, 349. 



Abundant, not only having procured it in northern California, but also as far south as Texas, 

 on the borders of the Rio Grande. Shy and wild in its habits, when startled it flies low 

 some distance, an&amp;lt;f plunging into a thicket alights, runs on the ground, and so conceals itself 

 that it is not again easily found. Its notes are equal in harmony to those of our mocking bird, 

 and among the miners it is well known as the California mocking bird. It incubates in the 

 country _, but the only nest I found, composed externally of coarse twigs and lined with fine roots, 

 contained young, it then being the month of July.
