General Notes .

2. Mimus polyglottus. Abundant in summer. Nesting in low 
bushes, grape-vines, etc. 
3. Harporhynchus crissalis. I saw this species on the Gila in New 
Mexico, and in Arizona, in brushy broken localities. Not common. 
4. Sialia mexicana. Abundant in winter. A few stay in the high 
mountains all summer. 
5. Sialia arctica. Yery scarce in winter. I saw not more than a 
dozen in the season. They frequent the low valleys. 
6. Auriparus flaviceps. Sparingly found in summer in broken 
localities along the Gila in New Mexico, usually in the mouths of canons at 
the edge of the river bottom. In Arizona frequents the mesquit. Nests 
in a low bushy tree, called there “ hackberry.” The nests are bulky, com- 
posed of thorny twigs on the outside, and lined with grass, with a small 
hole in one side. June 2 I found a nest containing four young birds able 
to fly ; June 16, another nest containing three eggs. The eggs were green, 
much blotched with brown. Very young birds have the head uniform in 
color with the back. 
7. Dendrceca blackburniae. I killed a female, near Fort Bayard, 
N. M., in May. 
8. Vireo vicinior. Bare. Found in rough broken localities in the 
bluffs bordering the Gila, keeping in the scrub oaks. They are very sh}' - . 
Their song is similar to that of V. plumbeus , but the pauses between the 
notes are not as distinct. 
9. Vireo pusillus. Common on the Gila. Nests in willow thickets, 
the nest being placed in a fork of a twig, usually about two feet from the 
ground. 
10. Hesperiphona vespertina. Sparingly found in piny districts in 
New Mexico, both summer and winter. 
11. Pipilo aberti. February 11, I saw several birds of this species in 
the cottonwoods on the Gila bottom near old Fort West, N. M. They 
were clinging to the bark of the larger trees like Nuthatches, searching 
for insects in the crevices. I never saw these birds away from the imme- 
diate bottom of the Gila or its larger tributaries. They usually nest in 
the thick willows, although I found one nest in a cottonwood-tree, thirty 
feet or more from the ground, concealed in a thick bunch of the mistle- 
toe, so common in such trees. They are abundant, but very shy at all 
times. 
12. Pipilo megalonyx. Yery abundant all through New Mexico and 
Arizona, in brushy districts. 
13. Pipilo • fuscus. Common over the same region as the last, but 
more partial to rocky localities. 
14. Pipilo chlorurus. Observed on the Gila during the early spring 
migration. 
15. Junco oregonus. This species, and var. annectens, are plenty in 
timber everywhere.
