the red-slmftcd flicker and the ant-eating woodpecker, and in south- 

 ern Texas with the golden-fronted woodpecker. The thin voice of 

 hairdi betrays his presence when he is hidden, but he is often in 

 evidence, peeking around a post or tree trunk at you. 



Where there are trees he nests in them, where there are none he 

 accommodates himself to circumstances and nests in yuccas, fence 

 posts, and telegraph poles. On throwing open a gate the traveler 

 is sometimes surprised by the screams of a brood in the gate post,
