General Notes. 93 



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. Very 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 inesquit. 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 buds have the head uniform in 

 color with the back. 



7. Dendrceca blackburniee. I killed a female, near Fort Bayard, 

 N. M., in May. 



8. Vireo vicinior. Rare. Found in rough broken localities in the 

 bluffs bordering the Gila, keeping in the scrub oaks. They are very shy. 

 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. Very 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.
