Under this heading I give a number of original notes, also additional and interesting information on the 
nesting habits of various specics. Many of these are from my correspondents and collectors in different 
parts of the United States. 
4. HAylocichla ustulata. 
Russet-backed Thrush. 
This species is recorded as having a very limited distribution, being 
mainly restricted to the Pacific coast region. The number of eggs in a 
set is usually five. A set of four collected by W. O. Emerson, near Hay- 
wards, California, is in my collection. They are of a light green, spotted 
variously with yellowish brown. They measure as follows: .gt by .69, 
.89 by .69, -g1 by .60, .83 by .66. 
These were taken from a nest which was placed in the forks ofa 
willow that overhung a running stream. The nest was composed of dead 
leaves and drifted straw, matted together with mud. 
10.  Oreoscoptes montanus. 
Sage Thrasher. 
The following, under the title of ‘‘ Notes from Colorado,” by D. D. 
Stone, I take from the December number (1882) of the ‘‘ Ornithologist 
and Oologist.”’** It undoubtedly refers to this bird: 
‘* Mountain mocking birds are quite plentiful in open places, but 
are seldom seen in the timber. 
‘« June 20.—Took two sets of four eggs,—one fresh and the other 
containing large embryos. The nests are a large, bulky affair, and were 
placed under a cverhanging rock in a deep railroad cut. Composed out- 
wardly of dead twigs loosely laid together and lined with fine dry grass 
and weeds. Dimensions outside: height 4% inches, width 9g inches, 
inside depth 2 inches, breadth 4 inches. 
‘‘June 25.—Found a nest under a rock in an old prospect hole far 
above timber line containing four fresh eggs. The parent bird when on 
the nest will allow itself to be nearly touched by the hand when it will 
slip off the nest and out of sight. The eggs average .68 by .g5. Ground
