That will leave an adult pair of pronghorns - antelope with black pronged horns - at the Hutchinson Zoo. The pair have produced previous progeny, and it is common for a zoo to sell animals to another zoo. In the case of theses babies, the Hutchinson Zoo's asking price was $600 for the female and $500 for the male, according to zoo curator Kiley Buggeln.

"They pay us for the animals, and they pay transportation," said zoo director Charlotte Poepperling.

Usually animals fly on commercial flights, but the Minnesota party arranged for a private plane to pick up the little pronghorns.

"They are doing wonderful," Buggeln said of the newborns.
