10. & 11. Pronghorn antelope--Wyoming (left)  New Mexico (right)

map showing range of pronghorns in the US from the Rockie Mountains west to the midwestIn the 1920’s we only had 20,000 pronghorns, but today, thanks to hunting laws and wildlife management paid for by hunters, there are 35 million antelope now living in the western United States. Pronghorns live in open prairie and desert country. Both the male and females have true bony horns, although those of the female are small. The horns are covered with sheaths of fused hairs, which are shed annually. The black horn that you see is the sheath. Pronghorns are known for their speed and have been clocked up to 50 miles per hour. The hair of the pronghorn is hollow, allowing it to be comfortable in the sun at over 100 degrees, and warm in the cold western winters.

When comparing these record-book bucks to the huge Alberta pronghorn, the scoring difference is mass. When scoring antelope, there are five mass measurements on each horn and one length measurement. When you see lots of “black” at the base of the horns, that’s a big pronghorn. The New Mexico antelope has long horns, but they are not heavy, compared to the Alberta pronghorn in the small conference room. The Wyoming buck barely made the record book. Just not a big antelope.
