Habits and hahltat. — Though greatly reduced in number, peccaries 

 are still common in southwestern Texas. They prefer rocky walls of 

 canyons and the vicinity of streams or hilltops where caverns and 

 hollows afford protection, to which they retire during midday. On 

 Las Moras Creek, in Kinney County, Texas, they often join herds of 

 domestic sAvine, feeding on roots, acorns, and pecan nuts in company 

 with the half-wild pigs known as '* razor-backs.'"
