The female foal was born at the zoo April 10th.

The Somali wild ass is a critically endangered wild member of the horse family.

The zoo says fewer than a thousand exist in desert areas of northeastern Africa.

The Saint Louis Zoo has seven of the 27 Somali wild asses in North America.

Only one other zoo in North America has bred the species.
