K Dixon 1951 Parus atricristatus Apr 17 Barton Creek, 4 mi SW Austin, 500 ft, Travis Co, Texas Partial overcast observed sun; calm. Titmouse called see see sa set set set from near buildings at edge of hill territory where I had watched pair previously). Was impressed with the nasal quality and sharpness of this call. I walked N along the base of the hill to the vicinity of stake # 41 (the only Titmice heard were at the base of the hill N of the path I descended). In this area which lay to the east of the draw where I had seen the pair in territory N a pair taken Apr 8 (538,539), I followed an individual ♂ for half an hour. I found him very wary as he sang in answer to ♂ NE. However this bird sang steadily as an unmated ♂ often will. I finally took a shot at him but apparently the distance was too great for a half load. I think he may have been the mate of the ♀ 537 taken Apr 8. From 8:00 - 10:00 I hunted in areas farther N with no success. I wounded 2 ♂♀ which escaped and found others difficult to stalk. This area seemed to have more live oaks than those I had worked in previously; perhaps because they were on higher ground of different drainage properties. At 10:00 I worked down the draw to where I had seen the pair N of 538-539's territory on Apr 8 but I did not hear any titmice in this area. I worked N again along that trail where I had wounded the first ♂ and encountered a pair of titmice in a grassy clearing
