"1 Bailey, Summer Birds of San Miguel County, N. M. 443 



ADDITIONS TO MITCHELL'S LIST OF THE SUMMER 

 BIRDS OF SAN MIGUEL COUNTY, NEW MEXICO.^ 



BY FLORENCE MERRIAM BAILEY."^ 



In the course of our Biological Survey work in the summer of 

 1903, when on our way from the Staked Plains to the southern 

 Rocky Mountains in June, and afterwards in rounding the south- 

 ern end of the mountains and following up the eastern side of the 

 range in July and August, Mr. Bailey and I spent nearly two 

 months in San Miguel County, crossing a large part of its terri- 

 tory. From the Staked Plains we drove north almost half way 

 across the county to the Canadian River, where we were only 

 about twenty-five miles from the eastern boundary of the county, 

 when we turned west, crossing to the extreme western boundary, 

 between Pecos and Glorieta. Through the northwest corner of 

 the county we made two sections, following north into Mora 

 County on the Pecos River Forest Reserve, and after our return 

 to Pecos making another north and south section, driving from 

 Bernal up through Las Vegas and across the northern line of 

 San Miguel into Mora County. 



In this way we worked the most marked types of country that 

 the county affords, crossing the plains, climbing the mesas that, 

 in the breaking down of the Rocky Mountain plateau are left as 

 river-cut blocks on the plains, following along the rich fertile bot- 

 toms and narrow canons of the Pecos River, and exploring the 

 mountains of the county on the way to the head of the Pecos. 

 The plains and mesas of the northeastern part of the county, 

 however, we did not visit at all, and work in that section should 

 be done to complete the county records. 



In the breeding season the birds of the treeless plains which 

 we crossed in the south central part of the county were Horned 

 Larks and Meadowlarks. the Meadowlarks being found only in
