47. Apr. 11 San Antonio, Bexar Co., Texas I returned to the city via the same route - little land along the 8 miles of highway remains in brush, being either cultivated or in residence use. This evening I talked with Mr. R. W. Guillen over the telephone. He has not been active in bird work for a dozen years or so but earlier had worked in large areas of southern Texas, often with A. J. Kinn. He told me that the Guadalupe River was a pretty accurate general dividing line between eastern and western faunas in Texas and that many of the eastern birds found in the Austin region played out between San Marcos and New Braunfels. He spoke of changes in local distribution, the House Finch appearing here about 1933 now a common nester. Cassin Sparrow common in some years, often with Black-throated Sparrow - now exceedingly rare Chimney Swift a recent addition to the local fauna Curve-billed Thrasher now here, not listed by A. J. Kinn Mr. Guillen said that he had known Mr. Athwater, an Englishman, and thought him exceedingly reliable. He mentioned no other local bird workers in addition to Kinn. He told of having shown a series of oddly-plumaged Bennett's Titmouse to Oberholser who stated, "Roy, don't bother about those accursed hybrids" Mr. Guillen also opined that the White-rumped Shrike did not make up more than 25% of the local population, the others being California or sonoriensis.
