black tail always disappearing in the bushes ahead of the horses as 

 you pass. 



When we were camped on the arid mesa of the Pecos River, 

 among the sounds that were ofteuest in our ears were the songs of 

 the mockingbird and nonpareil, the iterant pe-cos' of the scaled quail, 

 and the calls of the verdin and roadrunner, while, mingled with them, 

 always tinkling from the bushes, was the cheery little tune of 

 Amphispiza. Tra-ree' -rah, ree'-rah-ree was one of the commonest of 

 its varied modifications, and it was generally given with a burr like 

 that of the lark sparrow. On all our walks through the thorn brush 

 and climbs over the agave-speared hills we found the lovely little 

 bird everywhere, sitting on top of the bushes singing with head 

 thrown back in fine enjoyment of his bright lay. 



One small father bird, trying to attract us when we were taking 

 notes on the first plumage of his brood, after twittering and calling 

 in vain, flew excitedly to a bush top and fairly burst into song while 

 his mate was trailing over the ground beside us, with the result that 

 the brood grew so unmanageable that they popped out of the nest 

 faster than we could put them back!
