The curve-billed thrasher is abundant and tame as you go through 

 the thorn brush of southern Texas, especially as you approach 

 Mexico. Its big clay-colored figure is largely in evidence, perched 

 on the brush Dr flying on short wings with long tilting tail across the 

 road. Cactus, yuccas, and thorn brush are all liberally supplied 

 with its big thorny nests. When we were photographing one the 

 owner came so close that we could see the bright red of its eyes. As 

 the birds watched us they gave their liquid two-syllabled call, which 

 is one of the loud, dominant notes of the country. In a dr}- wash in 

 southern New Mexico, when we were preparing to photograph one 

 of the yucca nests, the brooding bird, who had been entirel}^ hidden 

 by the yucca spears, quietly slijiped out of the nest and disappeared 

 in the brush.
