SUMMER RESIDENT BIRDS OE BREWSTER COUNTY, 



TEXAS. 1 



BY THOS. H. MONTGOMERY, JR. 



The present paper embodies the avifaunistic results of a 

 collecting trip in Brewster County, from June 14 to July 5, 1904, 

 when it was my good fortune to accompany the State Mineralogi- 

 cal Survey. To the director of the Survey, my friend Dr. William 

 B. Phillips, I am greatly indebted for all the facilities placed at 

 my disposal. 



The region is one very little known to zoologists, though 

 Messrs. Oberholser and Bailey have collected in the Chisos 

 Mountains which lie at the southern part of the county. The 

 County of Brewster is situated in the southwestern part of Texas, 

 between the 103rd and 104th degrees of longitude, and the 29th 

 and 30th of latitude. Its southern border is the Rio Grande. A 

 detailed topographical map of this region is in process of prepara- 

 tion by the Mineralogical Survey. The trip commenced from the 

 town of Alpine, in the northwest, on the Southern Pacific Rail- 

 road ; we reached Altudo, about 12 miles to the east, June 14 and 

 remained there until the 19th; Altudo has an altitude of 4750 

 feet. From there we proceeded due east to the town of Mara- 

 thon, with an altitude of a little more than 4000 feet, where we 

 spent two days ; thence south, spending one night at Garden 

 Springs (3750 feet), one at Miller's Wells, then south to Marley's 

 Wells (4000 feet) where we camped from the 24th to the 27th of 

 June; then south again to Chisos Pen (3120 feet) where I 

 remained to July 6, from there making a trip of two days to Green 

 Gulch (4700 to 6000 feet) in the Chisos Mountains. 



The country traversed may be said to be characterized by high 

 and abrupt sierras, of volcanic rocks and limestones, bordering on 

 high plains thrown into series of what now appear as rolling hills. 

 Everywhere are the heavy marks of erosion. There is but little 

 water, here and there at long distances a rain pool in the moun- 

 tain sides, or a marshy spring in the plains ; water is so scarce
