Little attempt is made to paw away the snow to get these plants. Cedar is used throughout the winter where available in large quantities. Four of the most important winter foods are cutleaf daisy, paper flower, fleabane, and wild buckwheat. In late February, early annuals become available. Early spring flowers, which appear about the middle of March, are eagerly sought.
More grass is taken when new green growth appears in spring.
The breeding season of the pronghorn in Trans-Pecos Texas extends from the last week in August to the first week in October. The most vigorous bucks gather small harems of two to 14 does. Young bucks frequently linger at the outskirts of the harem herd and at times attempt to steal a doe or even to interfere with a mature buck in his mating activities. The master of the harem has an endless task in keeping his does together and warding off intruding bucks. The female hides her young ones, and at first the fawns are active only a small part of the day.
