Habits Hud habitat. — 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 swine, feeding on roots, acorns, and pecan nuts in company 

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

 bordered by blackish on either side. The muzzle, cheeks, and space 

 in front of the eye are brownish gray, annulated with darker. There
