7. Harporhynchus curvirostris palmeri Ridgw. Palmer’s Thrasher.—During the present trip this Thrasher was met with at various points in the desert region about Tucson and Camp Lowell, where it was one of the most abundant and characteristic summer birds. Its favorite haunts were barren wastes covered with cactuses and stunted mesquites; but, like many other desert species, it occasionally visited the more fertile valleys to drink at the springs and water-holes. At these latter places specimens were obtained without much difficulty, but on all other occasions they were exceedingly shy and wary. In February, 1880, Mr. Stephens found Palmer’s Thrasher at Phœnix, and he also took winter specimens along the San Pedro River.[[41]]
Numerous nests were taken. The one before me was placed in a cholla at a height of about seven feet. It is composed outwardly of large twigs, and is lined with bleached grasses. Although by no means a rude structure, it suffers by comparison with the nest of H. bendirei, its construction being simpler, and all the materials much coarser. The three eggs which it contained were only slightly incubated on June 14. They measure respectively 1.05×.82, 1.09×.82, and 1.08×.83. They are pale greenish-blue, finely and very evenly spotted with brown and lavender. The number of eggs making up this set was not exceeded in any of the others examined by Mr. Stephens.
